Trajectory Positioning Based on Kalman Filter BDS/GPS Data Fusion
In global satellite navigation system,high precision positioning is one of the key performance indexes.At present,China's self-developed Beidou satellite navigation system(hereinafter referred to as:BDS)and the US-led global Satellite Positioning System(GPS)are in a leading position in the world.Although its positioning ac-curacy is high,the inherent problems of hardware-level systems still cause positioning errors.Based on the Kalman filter method,the project integrates the positioning data of BDS and GPS through the dual-mode positioning mod-ule,which greatly improves the positioning accuracy and reduces the error.
