Abstract
In the attitude determination system exists not only the high-frequency errors, but also the low-frequency errors related to the satellite orbit latitude and time. The low-frequency errors would affect the location accuracy without GCPs, especially to the horizontal accuracy. In this paper, firstly, the factors that produce low-frequency errors and the solutions are analyzed. Secondly, the low-frequency errors are detected and compensated automatically during bundle adjustment in TH-1 satellite, thus the influence of location accuracy by low-frequency error is eliminated. At last, the verification is tested using data of TH-1. The experimental results show: low-frequency errors compensation can resolve the system error of position without GCP, and has played an important role in the consistency of global location accuracy for TH-1.
