摘要：

In this paper, the solving model of interger ambiguity and the algorithm of satellite selection were studied. The differential observation equation of wide-lane carrier phase was established in intergrated system and the differential interger ambiguity of wide lane was solved based on LAMBDA algorithm.Then, the differential interger ambiguity and coordinate correction parameters of single-frenquency carrier phase were obtained by taking differential interger ambiguity of wide lane into differential observation equation of single-frenquency carrier phase. Meanwhile, the fixed rate of ambiguity was enhanced by the algorithm of satellite selection in the solving of interger ambiguity. Test data on GPS, BDS and intergrated BDS/GPS with or without satellite selection was statistically analyzed. The results show that the intergrated BDS/GPS can significantly enhance the fixed rate of GPS or BDS ambiguity and the intergrated system with satellite selection is more accurate than that without satellite selection. © 2017, Editorial Board of Journal of CUMT.
