The simulation results show that the adopted technical method has the ability to detect data anomalies and ensures that the relative positioning ambiguity of Beidou is fixed. Compared with the reference baseline value, the relative positioning accuracy of Beido

The Application of Global Ionospheric Map in Deep Space Orbit Determinationsets show an obvious similarity and the correlation coefficients are within (0.943?–?0.977). Last, the BAC GIM products’ application in the “Tianwen-1” Mars Exploring Mission is also performed.

BDS-2 Broadcast Ephemeris Orbit Error Compensation Based on ABC-BP Neural Network and the orbit accuracy of broadcast ephemeris of different satellites is improved by 20%–80%. ABC-BP NN has higher accuracy than BP NN, and the results of 3 and 5?days of different orbit types show that it has better ability to control error accumulation, and has better error compensation results f
