    摘要:

    伪距误差是影响北斗卫星导航接收机定位精度的关键因素,本文提出一种基于伪距差分和自适应容积卡尔曼滤波(Cubature Kalman filter,CKF)的双级北斗导航接收机伪距误差补偿方法。该方法将伪距误差分为自有性误差和公共性误差两类,首先通过伪距差分方法补偿伪距自有性误差,其次设计量测噪声自适应CKF滤波器,对用户接收机运动系统状态进行估计,补偿伪距公共性误差。实验结果表明:载体静态时,双级补偿方法略优;载体动态时,双级补偿比单级补偿的定位误差减小显著,自适应CKF算法比CKF算法具有更好的对噪声和干扰的适应能力。

    Abstract:

    Pseudorange error is a key factor affecting the positioning accuracy of the BeiDou satellite navigation receiver. A two-stage pseudorange error compensation method based on the pseudorange difference and the adaptive cubature Kalman filter (CKF) for BeiDou navigation receiver is proposed in this paper. Pseudorange error is divided into the self error and the common error. Firstly, the self error is compensated with the pseudorange difference method. Secondly, the measure noise adaptive CKF filter is designed to estimate the state of the receiver moving system in order to compensate the common error. Experimental results show that the the two-stage compensation method is slightly better under static conditions. The two-stage compensation reduces the localization error significantly than the single-stage compensation when the carrier is dynamic, and the adaptive CKF algorithm has better adaptability to noise and interference than the CKF algorithm.
