| 摘要: |
| 在高动态与强干扰条件下,卫星导航接收机码跟踪环路与载波跟踪环路会出现异常抖动进而影响卫星导航接收机的授时精度,针对这一问题提出了一种新的基于抗野值Kalman滤波技术的卫星导航接收机授时方法。该方法可以有效消除码环与载波环的异常抖动对解算出的卫星钟差的影响,并且对连续出现的野值也有很好的剔除效果。同时该授时方法还可以有效地对卫星导航接收机的晶振频率误差进行估计,进而对1PPS(pulse per second)信号发生器的频率控制字进行调整,提高系统的授时精度。经过实验验证,该授时方法可以有效提高卫星导航接收机的授时精度以及授时系统的鲁棒性。 |

| Abstract: |
| For the high dynamic and strong jamming situation, the abnormal oscillation of code tracking loop and carrier tracking loop will affect the timing precision of the satellite navigation receiver. In order to solve this prob-lem, we put forward a new robust Kalman filter outlier suppression timing algorithm. This algorithm can eliminate the timing error caused by the abnormal oscillation of code tracking loop and carrier tracking one and can also elimi-nate the continuous outliers. This algorithm can estimate the error of the crystal and control the signal frequency for improving the timing precision. The experimental results and their analysis confirm preliminarily that the algorithm can improve the timing precision and robustness. |
