Science education is based on inquiry.

Science education for primary and middle school students should conform to children’s cognitive characteristics, care for their innate curiosity and imagination, and help them appreciate the wonderful fun of observing, thinking and experimenting like scientists.　　　　

Although there are many opinions on how to add science education in the "double reduction" of education, there is a consensus that strengthening science education is not only to increase the teaching of scientific knowledge, but also to cultivate scientific literacy. Scientific literacy has the characteristics of multi-factor and multi-dimensional organic integration, including not only scientific knowledge and methods, but also scientific thinking, scientific attitude and scientific spirit. From the perspective of education, every subject, every scene and every link related to literacy cultivation cannot be separated from inquiry. Whether it’s questioning, model building, hypothetical experiment, problem solving, system discovery, innovation and development … The whole process of exploring with the germination, jointing, flowering and results of scientific literacy is filled in the life experience of every subject of science education. It can be said that science education is alive and smart because of inquiry. Facing the future, science education for teenagers should be based on inquiry.

As a biological term, "root" is an important organ of plants, which is mainly responsible for absorbing water and minerals, fixing plants and storing nutrients. Its morphological structure can be changed according to plant species and growth environment. In the Chinese culture, which highly values understanding things, "root" has long gone beyond its original meaning and has multiple meanings such as root, root, root cause and basis. No matter how complicated and ever-changing things are, only by nourishing their roots and guarding their foundations can they be deeply rooted and endless. Science education for primary and middle school students should conform to children’s cognitive characteristics, care for their innate curiosity and imagination, and help them appreciate the wonderful fun of observing, thinking and experimenting like scientists. Only in this way can the seeds of scientific innovation take root in their hearts and grow wantonly, and then become a habit and a state of life. Inquiry is not only a way of learning, but also a scientific attitude, and it is also an innovative quality, which indicates that learners gain happiness, satisfaction and sense of accomplishment in learning, scientific research and creation through self-attempt, thus laying a solid foundation for lifelong enthusiasm for scientific exploration. Inquiry is of great value to science education. The inquiry characteristics of science education are fully demonstrated in a multi-level sense.

One is the premise of the experiment. Experiments in science education must be based on inquiry. Without the examination and discussion of phenomena and previous experience, the birth of research problems lacks cognitive basis and theoretical basis. Inquiry, as the premise of experiment, is often manifested as questioning and questioning. In the process of questioning and questioning, everyone can express their opinions and brainstorm, so that new ideas can be generated and the experimental direction can be clarified. As the saying goes, "the trace of suspicion must be observed", only by finding the driving problem that is really worth exploring and investigating, and roughly clarifying the ins and outs, can we preset the solution to the problem and start the scientific experiment pointing to new discoveries and inventions. Science education is guided by questions, and starts from questioning and exploring.

The second is the learning content. Inquiry does not lie in science education, but stays at the entrance of science education, but advances with science education and becomes a part of science education content. Because the purpose of science education is to "guide students to participate in inquiry practice extensively, combine learning with thinking, entertain and entertain, consciously acquire scientific knowledge, cultivate scientific spirit, improve scientific quality … and weave the dream of becoming a scientist". Guiding students to think, explore and solve problems like scientists is the natural move and practical action of science education.

The third is the way of thinking. If inquiry, as an experimental premise or learning content, is separated from science educators to some extent, then from the perspective of thinking mode, inquiry is really integrated into teaching wisdom. In the design of science education teaching scheme, teachers’ inquiry thinking can’t be absent. On the basis of insight into the learning situation and analysis of problems, teachers can correctly preset various problems that may occur in the experiment and explore solutions. Only in the process of implementation can they meet the river and bridge the ladder, leading students to the other side of science. As the saying goes, "those who teach, grow good and save those who lose", "what is done above, what is done below". When teachers implement science education with inquiry thinking, students will acquire inquiry thinking through immersion experience.

The fourth is the necessary character. The cultivation of scientific literacy is indispensable to interrogation and reflection on existing cognitive schemes and investigation and identification of existing facts. It is an essential feature and character of science education to bring interrogation, reflection and investigation into the thinking process and integrate it into the content of science education. In other words, inquiry is the internal need of the implementation of science education and the driving force for the promotion of science education. Without inquiry, there is no real science education; If we don’t plant the roots of inquiry, it will be difficult to see the effectiveness of science education.

Inquiry contains the spirit of reflection, experiment and identification, which has both negative actions and constructive pursuit. Exploration in a complete sense is the dialectical unity of cracking and constructing, denying and affirming, keeping right and innovating. Healthy, active and scientific exploration should strive to achieve the unity of the following aspects.

The first is the unity of scientific inquiry and value inquiry. Scientific inquiry is an inquiry based on facts, in order to pursue the truth and help to establish the truth. It combs and examines the existing cognition and scheme based on the facts or conditions that have been presented, so as to reveal the essence of things and find the law of things’ operation under the conditions of teaching experiments. Value inquiry is an inquiry based on belief, the pursuit of meaning and the establishment of spirit. Based on the value judgment of rejuvenating the country through science and education and cultivating people through virtue, it discriminates and chooses the existing education and teaching ideas, so as to provide direction and adjust the thinking and behavior of teachers and students and clarify the goal of individual growth. The two are not independent, and scientific inquiry contains the content of value inquiry, and value inquiry must also take scientific inquiry as a reference.

The second is the unity of students’ inquiry and teachers’ inquiry. Guiding students to explore and demonstrating existing knowledge and related experiments is an indispensable link and content of scientific literacy cultivation. But at the same time, this process also needs the follow-up of teachers’ inquiry, that is, to constantly revise, enrich and improve their teaching plans and learning scaffolding in response to students’ questions. Students’ inquiry and teachers’ inquiry in science education are closely related. Only emphasizing students’ inquiry while ignoring teachers’ inquiry, science education will inevitably fall into dogma and rigidity, and cannot effectively deal with students’ problems and challenges.

The third is the unity of cognitive inquiry and fact inquiry. The inquiry of science education itself presents as a cognitive inquiry, which includes the doubt and construction of cognition, the exploration and experience of scientific thinking, scientific attitude and scientific spirit, but the inquiry of cognitive concepts cannot be regarded as the whole of science education. Fact inquiry and material inquiry are the transformation, change and innovation of existing things, and their significance is also extraordinary. Although cognitive inquiry is helpful to the transformation of reality, it can’t replace practical strength and material strength after all. Only in fact inquiry, by transforming matter with practice, can the endogenous energy of inquiry be fully released.

Cultivating young people who have the potential of scientists and are willing to devote themselves to scientific research, and laying a solid foundation for building a socialist modern power in an all-round way, can not be separated from the practice and innovation of science education. Science education needs to strengthen the consciousness of inquiry, attach importance to cultivating inquiry thinking, and make inquiry an internal driving force to support students’ lifelong curiosity, continuous exploration and invention.

Steady start, busy production and full confidence (new economic orientation, vigorously boosting market confidence)

　　The Central Economic Work Conference emphasized that "more efforts should be made to promote the stable scale and excellent structure of foreign trade". In 2022, China’s import and export of goods broke the 40 trillion yuan mark for the first time, increasing by 7.7% to 42.07 trillion yuan; In 2023, it is necessary to maintain a continuous good trend of imports and exports and realize the important supporting effect of stable foreign trade on stable growth.

　　At the beginning of the new year, all localities and departments launched "service packages" and made every effort to achieve a "good start", laying a solid foundation for maintaining stability and improving quality of foreign trade imports and exports throughout the year. Our reporter interviewed this, watching foreign trade enterprises "run up", manufacturing "strengthen" and logistics channels "smooth up", and feeling the vitality and toughness of import and export.

　　Expand the market — —

　　An order to cross the ocean

　　The plane landed in Kuala Lumpur, Malaysia, and the tropical sunshine penetrated through the porthole, but Zheng Yijun’s heart was still uneasy.

　　As the chairman of Zhaotai Trading (Chongqing) Co., Ltd., he received a questionnaire from Chongqing Municipal Commission of Commerce at the end of last year: Are you interested in exploring markets in Southeast Asia? The company specializes in motorcycles, generators and micro-tillers, and goes deep into strange markets. No one takes the lead in organizing, so Zheng Yijun dare not take risks.

　　At the end of the year and the beginning of the year, the economic recovery ushered in a window period, and Chongqing took advantage of the situation to implement the international market development plan. "The survey shows that 96% of enterprises are interested, and 85% are willing to charter flights or assemble air crews." According to the relevant person in charge of the Chongqing Municipal Commission of Commerce, ASEAN is an important trading partner of Chongqing, and combined with the wishes of enterprises, the destination is Malaysia and Thailand.

　　The business group was busy, and Zheng Yijun kept on: the business office of the Chinese embassy, local departments and chambers of commerce visited them one by one; Local market inspection teams, offline matchmaking meetings of enterprises, and field connection … … During the activity, he also met "netizens" — — A motorcycle and agricultural machinery parts supplier, "in the past, online contact was intermittent, and cooperation failed."

　　This time, Zheng Yijun, with product brochures and samples, was finally able to sit down and talk with the other party: "We can provide all technical support and after-sales service; Goods are transported through the new land and sea passage in the west, with short time and favorable price, and can provide a package of logistics services … …”

　　"A thousand emails are not as good as meeting one another." Zheng Yijun said that the two sides signed a cooperation framework agreement on the spot.

　　During the visit, the delegation members of Chongqing Municipal Commission of Commerce introduced the basic situation and development advantages of Chongqing to foreign businessmen, while helping enterprises understand the local trade policies and investment environment. At the centralized signing ceremony of the first stop in Malaysia, nine Chongqing enterprises signed contracts with foreign parties for 11 projects, with an amount exceeding 100 million yuan.

　　This is the significance of "going out to sea in groups", which supports enterprises to meet customers, expand markets, sign orders and stabilize production. According to statistics, the total contracted amount of the business group this time is 30.88 million US dollars, involving the fields of communication, hardware, automobile and motorcycle, access control system, logistics full chain service, etc., and the largest single order reaches 5 million US dollars. The relevant person in charge of the Chongqing Municipal Commission of Commerce said: "This year, we plan to organize more than 100 delegations to support more than 1,000 enterprises to go abroad, participate in exhibitions, conduct business docking and visit customers."

　　Originally planned to talk about a contract of 1.85 million US dollars, but it didn’t happen. When I returned, I had already received a total order of 5 million US dollars. Zheng Yijun is no longer nervous when he first came, and he is full of confidence in his next trip.

　　Catch orders — —

　　A factory running at full speed

　　Dust-proof clothing, hats, masks and gloves … … Workers in full gear are busy and orderly.

　　In Shangyu District, Shaoxing, in the packaging workshop of Zhejiang Axilong Shunhua Aluminum Plastic Industry Co., Ltd., more than 40 production lines and more than 100 injection molding machines are fully powered.

　　Before and after the Spring Festival, Zhejiang foreign trade enterprises organized a delegation to go to sea and gained a lot. Axilong Shunhua, who specializes in the production of lipstick tubes, perfume covers and other cosmetic packaging materials, is ready to grab production and orders early.

　　Since the fourth day of the first month, Zhang Fang, a worker in the injection workshop, has been busy. This year, instead of returning to her hometown in Anhui, she responded to the call to stay in the factory for the New Year. "The government issued a subsidy from 1000 yuan, and our foreign employees also received an additional 1,500 yuan from the company." Zhang Fang said that the heavier the task, the higher the income, and everyone is full of energy.

　　"Not only employees, but also all aspects." Xu Baihua, general manager of the company, introduced that Shangyu Power Supply Company of Shaoxing City, State Grid, together with District Water Group and District Natural Gas Company, jointly inspected and maintained equipment and lines, providing reliable guarantee for enterprises to start construction.

　　On the basis of implementing 12 measures of "seizing the start and stabilizing growth" in the early stage, Shangyu District successively issued 24 policies, and arranged over 2 billion yuan of policy funds throughout the year to encourage enterprises to return to work quickly and stabilize production with "real money and silver".

　　Axilong Shunhua has a new factory building, which is expected to be put into trial operation in the second quarter. This is a water-based coating production line for cosmetic packaging materials, which can replace high-content volatile organic compounds such as ink and solve the problem of pollutant discharge from the source. "The government encourages source substitution and technology upgrading, and can get up to 30% subsidy for enterprise equipment investment!" Xu Baihua said.

　　Outside the factory, Chen Fengfei, director of the company’s marketing center, is seeing off visiting customers. "We intend to further explore overseas markets." She simply "settled down" in the office and studied the policy package of full dry goods: the company plans to go to Dubai, Monaco and other places to participate in exhibitions, and the booth fee subsidy can reach up to 100%; Inviting foreign businessmen to enter the country for business talks, enterprises can get a reward of 5,000 yuan/person … …

　　"We should take more measures to stabilize production, so that enterprises can gain a stronger sense of gain." According to the relevant person in charge of the Zhejiang Provincial Department of Commerce, this year, Zhejiang will further implement the action of expanding the market to grab orders and attract projects, and plans to hold 600 events, focusing on holding and supporting more than 130 exhibitions; Measures such as increasing special loans for foreign trade industries and speeding up the construction of foreign trade financial system will also be implemented continuously.

　　The policy is strong and the enterprise is confident. Chen Fengfei said: "In early February, we reached a follow-up cooperation intention with two foreign companies." According to the production situation of various factories, the company’s output value in the first quarter increased by at least 5% year-on-year, and the annual sales are expected to return to the peak before the epidemic.

　　Clear the way — —

　　An efficient and fast route

　　The whistle is long and spreads to the shore of Qingdao Port, Shandong Port, with the sea breeze in the morning. This is the sixth largest container port in the world and the largest port with the highest density of routes in northern China, with more than 220 container routes.

　　On February 19th, the "Oriental Belgium" freighter from the RCEP route firmly docked at the 105 berth in Qianwan Port Area, but the operation area was empty — —

　　"This is a fully automated terminal that has set a new world record for loading and unloading efficiency for 9 times. It integrates the Internet of Things, big data, artificial intelligence and automatic control, and runs automatically throughout the process." Li Qiang, deputy manager of Qingdao Port Automation Terminal Operation Department, explained that relying on the intelligent management and control system independently developed by Qingdao Port, the bridge crane automatically scans the outline of the ship and identifies the target position in real time; The guided vehicle is equipped with laser anti-collision system and ultrasonic sensing system to transport containers to the yard without interruption; According to the task issued by the system, the track crane completes the stacking and receiving operation … …

　　After the unloading, the container trucks next to the "Oriental Belgium" freighter came and went, while sending the imported goods to the Qingdao Customs inspection platform, accepting the supervision of customs information checking and machine inspection image inspection, and loading the exported goods for bridge crane loading.

　　The shipment has not been completed, and the customs supervision procedures have been completed. This efficiency is due to the convenience measures for the passage of ships on the RCEP route introduced by Qingdao Customs, and the perishable goods originating from RCEP member countries that have arrived at the supervision workplace and submitted the information completely are released within 6 hours.

　　Export customs clearance procedures can be handled online. "View, download and print online, without running errands and waiting on shore, saving time and reducing costs." Zhao Wenjuan, business manager of Rizhao Jinhe Biochemical Group Co., Ltd., shook the paper in his hand: "Look, the RCEP certificate of origin has also been completed in advance."

　　With this certificate, the tariff rate of the company’s 380 tons of citrate can be reduced from the original 5% to zero, and the tax reduction is over 120,000 yuan. Thanks to RCEP, the company expects export orders to increase by more than 15% this year.

　　In January 2022, the first RCEP certificate of origin in China was issued here. In January this year, Qingdao Customs issued 7,451 certificates, and the value of export goods was 1.67 billion yuan, up by 62.4% and 16% respectively. A total of 430 million yuan of imported goods were subject to RCEP preferential tax rate, and the tax concession was 24 million yuan, up 3 times and 3.6 times respectively. Bi Haijun, director of the Customs Department of Qingdao Customs, said: "We have also developed a smart collection and management system to accurately locate enterprises that are not enjoying benefits in the jurisdiction and guide them to enjoy dividends such as tariff concessions."

　　With the official entry into force of RCEP last year, the port economy has become more and more active. Qingdao Port has strengthened cooperation with key companies and opened up nearly 100 RCEP routes. Li Qiang said: "Since the beginning of this year, container throughput has increased by 10.4% year-on-year, berth efficiency has increased by 9.9% year-on-year, and the best results have been achieved in the same period."

　　At night, the "Oriental Belgium" freighter whistled again and set sail with full load. The cargo ship imported and exported a total of 1,129 natural containers, and the ship’s hourly efficiency reached 111.77 natural containers, leaving the berth two hours earlier than originally planned and arriving at the destination three days later.

Advanced guide to star wars brain powder： what do experts say about these unsolved mysteries

??1905 movie network exclusive feature For the young audience in China, the memory of Star Wars may be a little distant and vague. Although Jedi Knights, Darth Vader, Storm Soldiers and so on are all named, many people are vague about what the story is and what the role is.

Are you worried that those who don’t know this series can’t understand Star Wars: The Force Awakens?

Director Jeffrey Jacob Abrams said: "It doesn’t matter, the two leading men and women don’t understand Star Wars either. This is a brand-new story and adventure, which is about family and emotion. I believe everyone can find resonance from it."

The new hero and heroine in Star Wars: The Force Awakens

The main characters of the film are two new actors, and the heroine Daisy Ridley plays Lei. She is a scavenger living in the desert. There was a war there, leaving a lot of old spaceships. She lived there by picking up things while waiting for her family to come back hopelessly, but she was self-sufficient and didn’t rely on anyone else. The hero is Fen, played by john boyega. He used to be a stormtrooper of the First Order, which we are familiar with, but then he escaped from this evil organization. Then he met Lei and suddenly realized that he had entered a life-and-death adventure.

Kylo ren (adam driver), the villain they want to fight, is reminiscent of Darth Vader darth vader. He will also fulfill Vader’s mission and throw out the evil red color possessed by the Sith lightsaber, together with two other bad guys, Captain Fasma (gwendoline christie) and General hax (domhnall glesson).

All the alien monsters in Star Wars are actually made.

In addition, there is a new character BB-8 that has to be mentioned. It can roll and turn like a magnet snowball, and there is something similar to eyes on the hemispherical head, which is its sensor. It is said that BB-8 is actually an aerospace mechanic robot, which can be plugged into fighter planes like robots such as R2 and R4. It is reported that it was produced by a Muppet actor in the post-CG stage, and there are four different versions of it in the whole process. I wonder if you can see it when you watch the film.

Other strange alien creatures, however, will not be made in the later stage, but will be performed by operators and actors in various suits. There is a troll with three people hidden inside. ?

Of course, if you are a senior brain-dead fan of the Star Wars series, you will naturally be happier. In this film, the characters you are familiar with have also returned, such as R2-D2 robot and its good friend C-3PO, which appeared in all Star Wars movies, and our familiar captain Han Solo came back with Tshubaka in the Millennium Falcon, as well as various spacecraft such as the triangle spacecraft destroyer, X-wing fighter and TIE fighter, which made you feel good at once.

Anyone who is familiar with Star Wars knows that although this series of movies also tells everything about the universe, it is different from the hard science fiction of Mars Rescue. In its soft science fiction with fantasy and magic characteristics, the authenticity of science and technology and physics is not important.

However, since the first Star Wars was released in 1977, after more than 40 years, it has evolved from American pop culture to a magical cultural phenomenon. The characters, stories, settings and so on in the film have made many people not only hope, but even think that these are true. In the spirit of seeking truth and exploring, three foreign film editors actually visited a large number of scientific people to see how to use real-world technology and knowledge to solve several puzzles that have been bothering everyone in Star Wars-next, let’s walk into the "real" Star Wars world. . .

Princess Leia appeared again in The Force Awakens.

　　 The Star Wars series has created a whole cosmic framework, and naturally there are a lot of social structures. So, how does the whole Star Wars society work?

1. Is Princess Leia still a princess?

Poor Princess Leia, because she supported the rebellion, she lost her planet, her subjects and her motherland, her territory and her crown. Is she still a princess?

Linxi Wood, an assistant professor at Lancaster University, is studying the female inheritance of Tudor dynasty. He replied that the title of "princess" for a woman "is her birthright, not because of her marriage or meritorious service. It is precisely because of this that this title cannot be taken away. " In history, many heirs to the throne, or princes and princesses, remained princes and princesses after losing their territory. So this is a "bloodline problem" rather than a "property problem", so the tragic fate of Princess Leia does not mean that she is not a princess.

Kylo ren, the villain in this episode, looks like Darth Vader.

2. What criteria do you need to be a stormtrooper?

Well, so far, the only conscription standard we know is Princess Leia’s vicious comment: "Are you too short for a storm trooper?" It seems that the hardware requirement of storm troopers is to have a certain height. However, storm troopers are mostly clones, so it is not difficult to maintain the same height. But in the later period, the empire began to recruit stormtroopers, so there must be hard conditions.

Regarding this qualification, Laurie Cox, a history lecturer at St Andrews University, said: "The number of soldiers needed in Star Wars is astronomical, so the recruitment standard will definitely drop again. At the end of the period, all adult men can get equipment and go to the battlefield. In the middle world and modern history, many emperors and monarchs held amnesties to release some felons from prison and let them go to the front to participate in the war. " Therefore, judging from the history of human society, in those extreme cases, you don’t need any hard qualifications to become a storm soldier, as long as you are willing.

3. How long does it take to become a Jedi?

To be the evil side, Master Yoda put it this way: "Faster, easier and more attractive." So how long will it take for the young Jedi on the bright side to be promoted from Padawan to Jedi?

In the official description of Star Wars, it takes ten years to become a Jedi, and it must be one-on-one training. (This was before the revenge of the Sith destroyed all the Jedi training infrastructure) But on earth, becoming a Jedi is much easier.

In the Jedi Training Camp created by many Star Wars fans, you only need to apply and register to call yourself a Jedi. But if you want to pass four stages of training, it will take six months to a year. So far, this private organization called "Jedi Church" has 500,000 members, and has taught various metaphysical and theological contents — — Of course, lightsabers are not provided here.

BB-8 shouldn’t need decompression either.

4. What do the rebels do to kill time when they are not fighting?

When the rebels put away their wands, what can they do after getting up? Play a game? Or sitting in the coffee shop at the rebel base? Can they also enjoy the SPA? In the world of Star Wars, what are the entertainments like watching movies and chasing plays?

As long as there is no combat mission, the rebels’ leisure style may be similar to that of human beings. A researcher at the British Museum of Natural History explained: "The way for soldiers and sailors to pass the time is to pick up girls. Of course, they should choose carefully. This is the best way to decompress."

Then, the more frenzied question is coming. Do robots like R2-D2 also need decompression? Muri Shanahan, a professor of robotics in Imperial College London, said: "R2-D2 is definitely not what we now call artificial intelligence based on silicon atoms, CPU and software. I believe his processor is biological. If the rebel robot has such a biological brain, just like a computer, then he doesn’t need to rest. "

＂Beidou＂ navigation empowers industrial development to accelerate (new economic direction)

Recently, the "Beidou Travel Application Innovation Plan" initiated by domestic enterprises was launched, and the Beidou innovative application represented by "lane-level navigation" will be popularized nationwide from the current 8 city pilots. It is understood that the plan also includes functions such as dynamic traffic light countdown and equal light status based on Beidou’s core computing power. It is an innovative service launched by Beidou high-precision applications for the public, which will help Beidou in the industrialization of traffic travel scenes.

The latest data shows that the total output value of satellite navigation and location-based service industry in our country has reached about 470 billion yuan; as of January this year, the global cumulative access to intelligent devices of Beidou space-time intelligent services exceeded 1.50 billion units; Beidou high-precision space-time service was called more than 170 billion times a month, and the service covered more than 230 countries and regions around the world; Beidou became the "standard" of smart phones and wearable devices, and Autonavi maps called Beidou satellites for more than 300 billion times a day.

Beidou, which is "easy to use in the sky and good on the ground", has moved from solving the problem of "presence and absence" to a stage of development of "higher accuracy, more credibility and better service".

Scale applications continue to expand

In the northwest region, planting cotton requires high-precision linear film mulching. If the agricultural machine cannot guarantee the linear accuracy of the operation, it will not only affect the quality of the film mulching, resulting in "film cutting" and rework, but also not conducive to the later topping, harvesting and other links. At the same time, it will cause land waste, reduce production, and affect the income of cotton farmers.

Now, with the Beidou navigation agricultural machinery automatic driving system, cotton farmers only need to set the operation width and other data to ensure that the agricultural machinery is accurate and straight operation, on-demand seeds, ridge mulching and other procedures are completed in one go, and the sowing efficiency and quality are greatly improved. "In recent years, the’Huinong Beidou navigation automatic driving system ‘we have built is widely used in tractors, rice transplanters, harvesters, plant protection machines and some specific self-propelled vehicles, covering the whole operation link of plowing, sowing, transplanting, ditching, plant protection, harvesting, flat ground, etc. The operation accuracy can reach 2.5 cm, and the cumulative operation area of the system exceeds 50 million mu." Shen Jun, chief scientist of Beijing Hezhong Sizhuang Technology joint stock company, said.

Application is the life infra of Beidou development, and agriculture is the key area of Beidou application. In recent years, Beidou has supported the rapid development of precision agriculture in our country, and the agricultural machinery automatic driving system based on Beidou system has exceeded 100,000 units/sets. This year, the No. 1 document of the Central Committee proposes to support the integrated application of Beidou intelligent monitoring end point and auxiliary driving system.

From transportation to agriculture, forestry, animal husbandry and fishing, from smart ports to power inspections, Beidou provides time and space services like water, electricity, gas and other public services, fully integrated into the infrastructure, deeply empowering all walks of life, and gradually entering thousands of households, generating significant economic and social benefits.

In the bustling business center of Beijing, shared bicycles with Beidou high-precision positioning function are parked in the "electronic fence", which is convenient for users to use and convenient for staff to dispatch and clear in time. "These shared bicycles are equipped with Beidou high-precision positioning modules, which can achieve sub-meter-level (less than 1 meter) positioning accuracy in open scenes." According to Dou Ke, head of hardware research and development of Meituan bicycles, in order to further improve the real-time and accuracy of positioning, they have upgraded the smart lock chip of shared bicycles from 2G to 4G, and equipped with more advanced sensors to make vehicle scheduling more orderly.

Data show that as of the first half of 2022, Beidou has been applied in more than 20 industries (fields). The total application of Beidou products has exceeded 15.50 million units/set. At present, the number of shared bicycles equipped with domestic Beidou high-precision positioning chips has exceeded 5 million, covering more than 450 cities; among the smartphones applying for network access in China, the mobile phone shipments that support Beidou positioning account for more than 98%.

"Today, Beidou has become an important spatiotemporal infrastructure in our country and has also played an important supporting role in the development of the digital economy. The spatiotemporal data generated by Beidou is the’blood ‘of the digital economy, and the massive data accumulated by the digital economy provides a vast world for Beidou applications. The industry and the public application field have created more and more digital application scenarios of Beidou, which has effectively expanded the breadth and depth of Beidou applications." Yu Xiancheng, president of China Satellite Navigation and Positioning Association, said.

Deep integration with emerging technologies

To communicate with each other and play an effective empowering role, data needs to have a unified temporal and spatial benchmark for "alignment". Only with accurate and reliable "space-time labels" can an accurate mapping of the real world and the digital world be achieved, and space-time-based perception, calculation and collaboration can be realized. With the combination of Beidou with artificial intelligence, big data, cloud computing, 5G communication, etc., Beidou applications are also extending to emerging technologies.

"Lane-level navigation" is a typical application of spatiotemporal intelligence, and it is also the product of the deep integration of Beidou and various emerging technologies. "The so-called’lane-level navigation ‘means that users can obtain extremely high-precision positioning provided by mobile navigation applications during driving. On this basis, when drivers need to change lanes, such as near expressway turning intersections or high-speed ramp,’ lane-level navigation ‘will provide more detailed lane-level voice broadcasts and action guidance." Liu Zhenfei, president of Autonavi Maps, introduced.

Chen Jinpei, chief executive of Qianxun Location Network Co., Ltd., said: "Technically, we observe the navigation satellite signal through the National Beidou Ground-based Enhancement System, and calculate the high-precision calculation engine to provide high-precision differential correction data to the end point of the mobile phone. After that, the mobile phone combines the original satellite observation data to complete the algorithm solution and obtain sub-meter positioning accuracy. Finally, the positioning and navigation application combines high-precision positioning maps to provide users with lane-level fine navigation guidance."

The successful application of "lane-level navigation" is inseparable from the all-round upgrade of positioning antennas, positioning algorithms, positioning chips, mobile phone maps and other technical elements. Since 2019, domestic enterprises have carried out joint research in a number of software and hardware fields, and made breakthroughs in reducing the power consumption of positioning antennas, real-time dynamic measurement technology algorithms, and deep adaptation of mainstream chip manufacturers.

In the opinion of Yang Changfeng, chief designer of Beidou satellite navigation system engineering and academician of the Chinese Academy of Engineering, China Beidou in the new era insists on application in development and development in application, and should follow the concept of "financial network, financial data, financial end point, financial service", expand and strengthen the new business model of "Beidou +" and "+ Beidou", vigorously shape the consciousness of the whole industry chain, create an innovative consortium, realize the integrated development of the industry, and strive to be the first in the world to open up the full link of high-precision positioning of mobile phones.

Yu Xiancheng believes that space-time information, positioning and navigation services, as important information infrastructure, can only continue to maintain the leading and integration of technology, promote the development of application services to depth and breadth, and better and more fully empower space-time.

Industrial development ushered in a period of opportunity

At present, the large-scale application of Beidou has entered a critical period, and it is also an opportunity period for the development of the entire Beidou industry. The "2022 China Satellite Navigation and location-based service industry development white paper" shows that in 2021, our country’s industrial core output value including chips, devices, algorithms, etc. directly related to the research and development and application of satellite navigation technology will reach 145.40 billion yuan, and the related output value driven by satellite navigation applications and services will reach 323.60 billion yuan. The number of enterprises and institutions in the field of satellite navigation and location-based service in our country is about 14,000, and the number of employees is over 500,000.

Yu Xiancheng said that the industrial application of Beidou is in a period of major change, and it is necessary to face the competition, find another way, and strive for advantages. By breaking through the key core technologies of the industry, we can promote the cross-integration of Beidou and digital technology, and promote the deep integration of Beidou and the industry.

Deqing County, Huzhou, Zhejiang Province, is a beneficiary of the development of the Beidou industry. It focuses on the advantageous industries of "Beidou Dixin", expands and forms industrial clusters such as "Beidou Dixin + artificial intelligence", "Beidou Dixin + general aviation", and gathers 2 provincial key laboratories, 2 provincial new R & D institutions, and 22 provincial high-tech enterprise R & D centers. It has successfully created the business card of "Geographic Information Town" and created considerable economic benefits.

"Promoting the development of the Beidou navigation and location-based service industry is an important means to accelerate the process of economic digital transformation and empower the development of the digital economy," Yu Xiancheng said. During the "14th Five-Year Plan" period, our country will further promote the standardization and ubiquitous development of Beidou, give full play to the role of Beidou as an independent time and space benchmark, and provide ubiquitous precise time and space information services, and truly realize the large-scale and market-oriented development of Beidou application services.
