卫星与测站钟差支持条件下的GEO卫星精密定轨
Precise Orbit Determination for GEO Satellites Based on Both Satellite Clock Offsets and Station Clock Offsets
摘要
Abstract
Because of its dynamical features, orbit parameters of the Geostationary satellite （GEO） are strongly correlated with clock offset parameters in Precise Orbit Determination （POD） when using the L-band pseudorange data. In order to solve this problem, clock offsets of the satellite clock as well as the receiver clock are introduced, which are obtained by unattached observation technology. Therefore, the psendorange data could be converted to ranging data. This paper discussed the GEO POD principle based on pseudorange data with the support of clock offsets, and analyzed the POD accuracy using simulation data from China regional tracking network. Influences from the clock offsets a2 item and errors of the satellite clock offset, stations＇ clock offsets and systematic errors were analyzed both theoretically and quantitatively.关键词
