摘要
Abstract
In the traditional INS- assisted- based carrier tracking loop, the problem is that the assisted performance is determined by the precision of INS. The architecture of INS assisted carrier tracking loop based on the EKF is proposed to solute the previous problem in this paper. The architecture of carrier tracking loop and INS-assisted carrier tracking loop are introduced, the factors influencing the tracking accuracy are analyzed, and the EKF-based loop architecture and the filter model are designed. The simulation results show that, the INS-assisted carrier tracking loop based on the EKF can suppress the noises of the carrier phase tracking errors, improve the assist performance of INS for carrier loop, and lessen the dependence on the precision of INS.关键词
