Comparison of Two Methods of Precise Orbit Determination of Beidou Satellites
Abstract The principles of and differences between Beidou single-system and multi-system zero-difference precise orbit determination are presented. Their respective precision is compared based on real observation data. The results show that the precision of two methods is comparable in current conditions. The three-dimension orbit precision of GEO can reach about 1 m, and that of IGSO and MEO can reach 0.2—0.3 m. Their radial precision is better than 10 cm.
