GPS/BD2 Dual-System Positioning Algorithm Analysis and Test
-
Abstract
This paper analyzed the dual satellite system positioning algorithm based on KALMAN filter and implemented it in a multi-system GNSS receiver.Then a static scenario positioning test in Hangzhou City has been carried out.The GPS/BD2 dual system mode obviously has better performance than the single system mode.Test result also revealed that the positioning precision of BD2 was comparable with GPS.
