多项式预测GNSS信号矢量跟踪算法
Polynomial prediction GNSS vector tracking algorithm
摘要
Abstract
A polynomial prediction Global Navigation Satellite System(GNSS) vector tracking algorithm is proposed, which is independent of the prior information of the receiver’s kinematic parameters. It is different from traditional Kalman filter which requires a proper dynamic model and adjusting its state noise according to the target’s kinematic status. The adaptive measurement noise estimation is also applied to guarantee a more robust tracking process. Numerical simulations validate that the algorithm proposed is able to track the target’s status accurately, and performs well in situations with different accelerations. It can also keep tracking when there occurs abrupt change in acceleration, thus avoiding the problems caused by traditional Kalman models which require proper parameter selections.关键词
