Abstract:

With the development of BDS,the global networking process is carried out,BDS/GPS integrated navigation has become an important method to improve the performance of navigation,and the ground augmentation system (GBAS),as a new generation of navigation mode for precision navigation,is the focus of current research.In this paper,through the derivation of BDS/GPS double system combined GBAS model,respectively to BDS,GPS as independent GBAS navigation source and BDS/GPS navigation accuracy as factor GBAS navigation source system (DOP),vertical protection level (VPL) performance are analyzed,and the superiority of GBAS performance in integrated navigation system is verified.The result shows that GBAS based on GPS and BDS are close to each other and have their respective advantages,BDS/GPS combined GBAS outperforms the single system.

Key words: integrated navigation, GBAS, DOP, VPL, integrity
