Abstract

For LEO orbit determination based on Bi-satellite Positioning System (BPS), trajectory error of positioning satellites becomes bottle-neck which improves orbit precision of LEO, so we can take combined orbit determination strategy of BPS and user satellites (LEO) to ameliorate precision. This paper integrates whole network adjustment algorithm into satellite precise orbit determination technology, and brings forward multi-LEO combined orbit determination satellite- network conception based on BPS. Then this paper establishes combined orbit determination models and satellites orbit parameters estimation algorithm based on numerical integral fusion algorithm, and emphasizes on discussing partial parameters weighing adjustment data processing algorithm. Simulation computation results show that whole network adjustment algorithm can ameliorate combined orbit determination precision of satellite network effectively.
