| 摘 要： | 采用自适应选权滤波法,对低动态精密单点定位的解算方法进行研究,并编写了精密单点定位程序。通过合理选择自适应因子参数,对船载动态GPS测量数据进行了事后精密单点定位处理。结果表明:相对于经典卡尔曼滤波方法,采用自适应选权滤波法可大大提高低动态精密单点定位解的精度,X、Y、Z三个方向的RMS分别提高了79.9%、69.7%和92.0%。

| Abstract: | Using the adaptive filtering by selection of the parameter weights method, we study on the low dynamic precise point positioning solution method, and compile the precise point positioning program. Through the reasonable selection of adaptive factor parameter, the ship dynamic GPS measurements are processed after PPP treatment. The results showed that： compared to the classical Calman filter method, the adaptive filtering by selection of the parameter weights method can greatly improve the accuracy of the solution of low dynamic PPP with X, Y and Z directional RMS increasing by 79.9% ,69.7% and 92.0% respectively. |
