| 摘 要： | 对流层延迟是GPS定位的主要误差源之一，一直是高精度GPS定位的障碍。本文针对湿分量延迟计算复杂，影响因素多，经模型改正后也不理想的现实情况，巧妙的使用IGS产品推算对流层延迟湿分量，进一步削弱了GPS定位中对流层延迟的影响，得出了一些有益的结论。

| Abstract: | Tropospheric propagation delay is one of the major error sources for GPS positioning,and it is also an obstacle for high accuracy GPS positioning. This paper explains practical things about complex computation,many influencing factors and dissatisfied corrections by models of wet component delay. Wet component of tropospheric propagation delay is calculated by using IGS products subtly,it can further weaken the influence of tropospheric propagation delay for GPS positioning,and draw some useful conclusions. |
