An integrated navigation system of Beidou satellite navigation system( BDS)/strapdown inertial navigation system( SINS)/magnetometer/vehicle ECU is designed using STM32 F407 as the core processor of the control system. The output of the control parameters such as longitude and latitude
heading angle and speed is realized. At the same time
the navigation information such as heading angle
speed
position and the navigation information obtained by BDS analysis is combined by using the improved track estimation algorithm. The combination information is processed by Kalman filtering algorithm. Finally
the actual vehicle motion measurement experiment is done and the result is good. The result shows that the design has a certain practical value.
