From which fields did such a simple and convenient Beidou system begin to be widely used?

First of all, Beidou system has been used in all cities in China. We also quickly judge the changes of satellite attitude and angular velocity telemetry, and compare them with the telemetry changes of several satellites in the same incident before, and finally get? Are the solar wings deployed? And report to the flight control captain at the first time that the flight plan can continue. The solar panel behind is slowly facing the sun, and the temperature telemetry and current telemetry of the solar wing are increasing steadily, which further proves that our previous conclusion is correct.

Secondly, it has been widely used in transportation, agriculture, forestry and fishery, hydrological monitoring, communication timing, disaster relief, public safety and other fields. More than half of the countries in the world began to use Beidou system. The unique role of Beidou system in emergency rescue and disaster relief lies in its? Stunt? The short message communication function is unique among the four major satellite navigation systems in the world. Short message communication is similar to the short message function of navigation terminal. The short message of Beidou-3 system has been upgraded from 120 to 1000, which can transmit more information.

Furthermore, the upstream of Beidou industrial chain is the foundation of satellite navigation industry, which mainly includes satellite manufacturing, satellite launch and ground-based and satellite-based augmentation systems for improving positioning accuracy. The middle reaches of Beidou industry mainly include basic components and Beidou terminals. Among them, the basic components are? Self-control? The most critical part is mainly composed of baseband chip, RF chip, board and antenna. Beidou terminal is the focus of Beidou application in the future, and has been applied to many industries such as transportation, maritime affairs, electric power, civil affairs, meteorology, fisheries, surveying and mapping.

Besides, we should know that satellite navigation system is a huge project. Beidou's 1, 2 and 3 are actually the three steps of Beidou. Beidou-1 is a test system with regional test service as its main goal. Has been completely retired and is not included in the official constellation; Beidou-2 is mainly a regional navigation system, mainly serving the Asia-Pacific region. For example, the clock system of TV station will connect GPS and Beidou to ensure two-way clock synchronization; Beidou-3 is a global satellite navigation system, which provides high-precision, all-weather and all-day navigation, positioning and timing services for the whole world.
