J. Borgmanthese two types of ambiguities can be used as a quality index of orbit and clock. After that, three types of BDS precise orbit and clock products, namely final determined products and real-time predicted and filtering products, are collected and produced.

Firstly, MSSA and LS methods are used to analyze the characteristics of the ZTD residual and determine the periodic signals and establish a ZTD residual model considering annual, semiannual, and seasonal period, and then establi

A. Boksenbergved. The accuracy of BDGIM model in the Northern hemisphere is better than that in the Southern, and the correction ratio is better than 75% over China and exceed 65% worldwide. Compared with the SPP results of using BDSKlob model, the positioning accuracy based on BDGIM model is improved by 25% and
