Abstract
The four major satellite navigation suppliers announced by the International Committee on Global Navigation Satellite Systems (ICG) include GPS of the United States, GLONASS of Russia, BDS of China and Galileo of Europe. The development of the four satellite navigation systems not only changes the trajectory of human activities on the earth’s surface, but also provides a cheap and efficient way for the accurate positioning and timing of other aircraft. Due to its low orbit and fast speed, LEO satellite naturally has the characteristics of strong landing power, fast revisit cycle, high ground resolution and fast observation geometry change, which makes it attracted much attention in the fields of mobile communication, remote sensing detection and navigation enhancement, and so on. In addition to the relatively weak irradiation environment, low launch cost and economic advantages, LEO constellation has become a direction that could not be ignored in various fields in recent years. Based on GNSS technology, this paper studied the theoretical method and achievable accuracy of precise orbit determination and time synchronization of LEO constellation. On this basis, the degraded backup effect and application suggestions of LEO constellation under multi-layer architecture including GNSS system were studied.
