The satellite radio determination system was used with Geostationary Orbit (GEO) satellites as the navigation constellation, and S, L‐frequency bands as operating frequencies to complete the regional satellite navigation system covering land and sea of our country. This chapter discusses the impact of orbital altitude on the number of satellites, constellation availability, accuracy, and describes the selection for the types of satellite orbits, which is considered based on the integrity of satellite navigation. Global Positioning System (GPS) positioning is divided into authorized users and non‐authorized users according to the user objects: authorized users use precise positioning service PPS, while non‐authorized users use standard location service SPS, and the selective availability (SA) can be carried out according to national security needs. Satellite navigation system presents the motion trail of satellites and users by time, and the satellite navigation can solve the users' location, speed, and time.
