Has the Beidou system entered people’s lives?

It has now entered people’s lives.

In 2019, the overall output value of China's satellite navigation and location services industry reached 345 billion yuan. The integration and development of Beidou with new technologies such as the Internet, big data, and artificial intelligence are building an emerging industrial ecological chain with Beidou spatio-temporal information as the main content, and it is becoming a new engine and booster for the rapid development of the Beidou industry, promoting production and life. Method changes and continuous innovation of business models.

According to China Daily, 15 years after the launch of the first satellite of the Beidou system, it generates an annual turnover of US$31.5 million for several large enterprises, including China Aerospace Science and Industry Corporation, AutoNavi Software Ltd. and China Ordnance Industry Corporation.

As of mid-2020, the Beidou-based agricultural machinery operation supervision platform has realized remote management and precise operation of agricultural machinery, serving more than 50,000 agricultural machinery equipment, increasing precision agricultural output by 5%, and saving agricultural machinery fuel consumption by 10%.

As of the end of 2019, China has more than 6.5 million operating vehicles, 30,000 postal and express delivery vehicles, approximately 80,000 buses in 36 central cities, more than 3,200 inland navigation facilities, and more than 2,900 maritime navigation facilities. The facility has applied the Beidou system.

Currently, 3-level platforms at the ministry, provincial, and city (county) levels have been built to achieve level 6 business applications, and more than 45,000 Beidou terminals have been promoted. Disaster-stricken areas use the Beidou short message function to promptly report disaster locations, sudden disaster information, and disaster area relief information. Civil affairs departments at all levels use Beidou terminals to query, manage and monitor disaster relief materials, greatly improving the management and transportation of disaster relief materials across the country.

Mainstream chip manufacturers at home and abroad have launched integrated communication chips that are compatible with the Beidou system. According to statistics, in the first quarter of 2019, 116 mobile phone models applied for network access in the Chinese market had positioning functions, of which 82 models supported Beidou positioning, and the Beidou positioning support rate reached 70%.

Smart wearable devices such as watches and bracelets that support the Beidou system, as well as special care products such as student cards and senior citizen cards, continue to emerge and are widely used.

In addition, the Beidou system is also widely used in land rights confirmation in Indonesia, construction in Kuwait, land testing in Uganda, precision agriculture in Myanmar, offshore piling in the Maldives, warehousing and logistics in Thailand, airport timing in Pakistan, and power inspection in Russia. different areas.

Extended information:

After the Beidou satellite navigation test system became available for use in 2000, its positioning accuracy was 100 meters. After calibration using a ground reference station, it was 20 meters, which was the same as the global satellites at that time. The civil code of the positioning system is equivalent. System users can realize their own positioning, and can also report their position and send messages to the outside world. The timing accuracy is 20 nanoseconds and the positioning response time is 1 second.

Because it uses a small number of satellites to achieve active positioning, the system cost is low, but the system is limited in positioning accuracy, user capacity, frequency of positioning, and concealment. In addition, the system has no speed measurement function and cannot be used for precision-guided weapons. Therefore, in case of possible conflicts, the use of formal systems is necessary and cannot be used as a backup.
