Accurate carrier phase measurement is an important research focus in precise ranging.Because the traditional extended Kalman filter(EKF) has some limitations in dynamic environments with insufficient priori information,this paper proposes a carrier tracking algorithm based on adaptive extended Kalman filter(AEKF).This algorithm monitors the changes in innovations or residuals to correct the process and measurement noise covariances,and then adjusts the filter gain to control the weights between the predicte...
