一种新的高动态GPS载波跟踪算法
Novel high dynamic GPS carrier tracking algorithm
摘要
Abstract
A high dynamic GPS carrier tracking loop based on Unscented Particle Filter(UPF) algorithm is proposed. The simulations, which are taken under both Gaussian and non-Gaussian noise environments, not only analyze its tracking performance for high dynamic GPS signal but also compare with the tracking loops based on Extended Kalman Filter(EKF), Unscented Kalman Filter(UKF), Particle Filter(PF) and Extended Particle Filter(EPF) algorithms. The result illustrates this new tracking loop has superior tracking performance in high-dynamic, weak signal or non-Gaussian noise environments. The use of UPF algorithm improves the tracking accuracy, and also solves the problem caused by non-Gaussian noise. The effectiveness of this scheme is verified by experiments.关键词
