A Multi-GNSS Pseudorange Positioning Method with Inter System Bias
Abstract In this paper, with the derivation of code observation equation, the structure and influence factors of inter system bias are analyzed. We discover that all factors for low precision navigation can be treated as related to satellite number. A new inter system bias parameter estimation solution is proposed. Finally, the new solution is applied to multi-GNSS positioning, providing reliable positioning information for real-time low precision users when only 4 multi-GNSS satellites are visible.
Key words :
