Abstract :
The design of tracking loop filter for software GPS receiver is flexible, and the performances of different tracking loop filters are analyzed in software receiver. The design methods and characteristics of second-order tracking loop filter, the third-order tracking loop filter, and the second-order IMU-assisted-based tracking loop filter are introduced. The tracking loop filter model based on the Kalman filter is designed, and the simulation result shows that, the Kalman tracking loop filter can accurately track the dynamic signal. Because that the IMU can remove most of dynamics from the incoming signal between the satellite and receiver, allowing for a tightening of the signal tracking loops and a commensurate improvement in noise mitigation.
