| 摘 要： | 卫星钟差预报在实时高精度导航定位中具有重要作用,Kalman滤波模型是预报卫星钟差的重要方法之一。为了进一步提高Kalman滤波模型预报卫星钟差的精度,本文提出了基于小波降噪的Kalman滤波模型预报卫星钟差。该模型使用小波降噪后数据,在保留Kalman滤波模型特点的基础上,明显地提高了短期卫星钟差预报精度。 |
| 关 键 词： | 卫星钟差 预报 Kalman滤波 降噪 精度 |

| Abstract: | Satellite clock prediction plays an important role in the real-time high accuracy navigation and positioning,and Kalman Filter(KF) is one of the important models for the satellite clock prediction.In order to improve the prediction accuracy,Wavelet De-noising Kalman Filter(WDKF) was put forward in the paper.WDKF model used the data which are de-noised by wavelet.While the characteristics of KF remained in WDKF,which could obviously improve short-term prediction accuracy. |
| Keywords: | satellite clock prediction Kalman filter de-noise accuracy |
