Has Beidou system entered people's lives?
In 20 19, the total output value of satellite navigation and location services in China reached 345 billion yuan. The integrated development of new technologies such as Beidou, Internet, big data, artificial intelligence, etc. is building an emerging industrial ecological chain with Beidou spatio-temporal information as the main content, and is becoming a new engine and booster for the rapid development of Beidou industry, promoting the change of production and lifestyle and the continuous innovation of business models.
According to China Daily, after the first satellite of Beidou system was launched 15 years ago, its annual turnover for many large enterprises such as China Aerospace Science and Industry Group, Gaode Software Co., Ltd. and China Ordnance Industry Corporation reached as high as 310.5 million US dollars.
By the middle of 2020, the agricultural machinery operation supervision platform based on Beidou has realized remote management and precise operation of agricultural machinery, served more than 50,000 sets of agricultural machinery equipment, increased the output of precision agriculture by 5%, and saved the oil consumption of agricultural machinery by 10%.
By the end of 20 19, China had more than 6.5 million operating vehicles, 30,000 postal and express vehicles, about 80,000 buses, more than 3,200 inland navigation facilities and more than 2,900 maritime navigation facilities in 36 central cities.
At present, a three-level platform of ministries, provinces and cities (counties) has been built, realizing six-level business applications and promoting more than 45,000 Beidou terminals. Disaster-stricken areas use Beidou short message function to report disaster location, sudden disaster information and disaster relief information in time. Civil affairs departments at all levels inquire, manage and monitor relief materials through Beidou terminal, which greatly improves the management and transportation level of relief materials throughout the country.
Mainstream chip manufacturers at home and abroad have introduced integrated chips compatible with Beidou system. According to statistics, in the first quarter of 20 19, there were 1 16 mobile phones with positioning function in China market, of which 82 supported Beidou positioning, and the positioning support rate of Beidou reached 70%.
Smart wearable devices such as watches and bracelets that support Beidou system, as well as special care products such as student cards and old-age cards, are constantly emerging and widely used.
In addition, Beidou system is also widely used in land confirmation in Indonesia, construction in Kuwait, land detection in Uganda, precision agriculture in Myanmar, offshore piling in Maldives, warehousing and logistics in Thailand, airport timing in Pakistan and power inspection in Russia.
Extended data:
After the Beidou satellite navigation test system was put into use in 2000, the positioning accuracy was 100 m, and it was 20 m after calibration by ground reference station, which was equivalent to the civil code of global positioning system at that time. Users of this system can realize their own positioning, report their own position and send messages to the outside world. The timing accuracy is 20 nanoseconds and the positioning response time is 1 second.
Because active positioning is realized by a few satellites, the system cost is low, but the system is limited in positioning accuracy, user capacity, positioning frequency and concealment. In addition, the system has no speed measuring function and cannot be used for precision guided weapons. Therefore, it is necessary to use the formal system in possible conflicts, and it cannot be used as a backup.
