Wang Le - Technology of BDS Real-time Precise Orbit Determination Enhanced by LEOs - October 29, 2018 • 387 Views
BDS ground control monitoring stations are unevenly distributed, and most are located in China. Aiming at the problem of low accuracy of orbit determination based on the existing BDS stations, the technology of combining Low Earth Orbit satellites with ground monitoring stations to calculate BDS satellites orbit parameters, LEO satellites orbit parameters and other parameters is proposed. Based on the orbit determination principle, a joint processing mathematical model of LEO satellites and ground monitoring stations data is studied, the calculation strategy is optimized, the data processing flow is designed inthis paper.
