GPS positioning is a complex system that will be affected by various factors during use, mainly divided into four types:
1、 SA
The US government, based on national interests, artificially reduces the accuracy of GPS navigation and positioning for ordinary users by limiting the accuracy of GPS positioning, GPS reference signals, and high-frequency jitter.
2、 Satellite ephemeris error
In GPS positioning, calculating the GPS navigation parameters of satellite position at certain times requires various types of ephemeris tables. However, regardless of the ephemeris method used, the calculated satellite position will be different from its actual position, which is called ephemeris error.
Thirdly, satellite clock deviation
Satellite clock bias includes clock bias, frequency offset, frequency drift, and random clock errors. In GPS measurement, both code phase observation and carrier phase observation require strict synchronization between the satellite clock and the receiving clock. Although all GPS satellites have high-precision atomic clocks (rubidium and cesium), there is still a time difference between them and the ideal GPS.
