摘要:
A method of zero-differenced multi-GNSS joint precise orbit determination of BeiDou satellites based on ambiguity fixing was present. The realization of ambiguity fixing was focused on. The real data was analyzed, and the results show that the three dimensional precision of GEO, IGSO and MEO can respectively reach 1.263, 0.241 and 0.134 m. The radial precision of the three types of satellites is averagely better than 10 cm, and that of IGSO and MEO is mostly better than 5 cm. After ambiguity fixing, the three dimensional precision of BDS is improved 21.8 % averagely, and the tangential precision is improved most obviously, especially for GEO.
