Although the basic functions of a satellite navigation system are only navigation, positioning, speed measurement, and timing, the application projects resulting from the secondary development of these basic functions in all walks of life will definitely dazzle you and lament your lack of imagination.

　　If the watch you wear is equipped with a navigation chip and uses the timing function of Beidou, then as long as your watch is not broken, you will never need to adjust the time;

　　If the elderly and children are equipped with Beidou receivers, they can accurately know their location and network with the public security system to provide them with safety protection;

　　In building construction, the Beidou system can be used to monitor the deformation of buildings, bridges and in use at millimeter and sub-millimeter levels to prevent collapse accidents caused by deformation;

　　In the field of forest fire prevention, the Beidou positioning receiver with communication function is installed on the fire truck, which can guide the vehicle and firefighters to the fire point to carry out disaster relief;

　　In the field of geophysics, the Beidou system is used to monitor the movement of the global crustal plates, and earthquakes can be found and predicted;

　　In the field of transportation, the Beidou system will have broad application prospects in intelligent transportation, road condition information management, road congestion control, vehicle monitoring and vehicle autonomous navigation;

　　In agriculture, the real-time precise positioning of Beidou will be applied to the arrangement and management of land and farmland to realize precision farming of farmland;

　　In terms of fishery, combined with the characteristics of fish migrating regularly with ocean currents, the positioning of the Beidou system can help fishermen find the location of the fish.

　　Let me tell you another example, the construction of the Three Gorges Dam, which has attracted worldwide attention, the dam roller is equipped with a Beidou navigation terminal. dam construction quality.

　　Therefore, some people have said that it is not unreasonable to say that the application of satellite navigation is only limited by imagination.
