Does China have its own satellite navigation system?

Since the development of Beidou system was started in the 199s, it has gone through three stages: Beidou No.1 system, Beidou No.2 system and Beidou No.3 system. From active to passive, from regional to global, the service positioning accuracy, system stability and comprehensive functions have been continuously improved, and it has become an important national space infrastructure, fully supporting the needs of national security and economic and social development. After the Beidou-3 is networked, the positioning accuracy is 2.5-5 meters, the service life of a single satellite is 1-12 years, and the service scope can cover the whole world. Together with American GPS, Russian Glonass and European Union Galileo, it constitutes the four major satellite navigation systems in the world.

Beidou application

It is understood that the service capacity of Beidou-3 system is 1 times higher than that of Beidou-2 system, and it will provide universal services in the fields of communication, electric power, finance, surveying and mapping, transportation, fishery, agriculture and forestry.

The Beidou No.3 positioning module supported by p>SKYLAB in B1C frequency band is divided into L1+L5 dual-frequency Beidou No.3 positioning modules according to the frequency band of receiving satellite signals, and the models are SKG122S and SKG122Y； respectively; L1 single-frequency Beidou No.3 positioning module, the models are SKG1223 which only supports Beidou positioning and SKG122C and SKG123Q which support single-mode and multi-mode positioning.
