| 摘 要： | 提出了一种利用非组合精密单点定位（PPP）提取区域电离层延迟的方法,并将区域电离层延迟内插至用户站实施单频仿动态PPP,以检验电离层延迟的提取精度。结果表明,电离层延迟内插精度受电离层活动变化影响较小,2 d内均能保证优于1 dm;单频仿动态PPP的定位精度在平面方向约为4~5 cm,高程方向优于1 dm;为便于比较分...

| Abstract: | A new method of regional ionosphere delays' calibration based on uncombined precise point positioning(PPP) is proposed in this paper,and the accuracy is assessed by interpolating the calibrated delays at a user station with single frequency simulated kinematic PPP implementation.The results show that the accuracy of interpolation is better than 1 dm and less affected by the ionosphere activity;the positioning accuracy of single frequency simulated kinematic PPP are 4~5 cm for panel and better than 1 dm for ... |
