卫星多普勒定位

在卫星多普勒定位工作中，数据预处理是必不可少的工作之一。

Pre-processing of data is one of the essential works for Doppler satellite positioning .

卫星多普勒定位主要误差源，星历误差和折射误差在同步跟踪一次卫星通过的两测站之间是相关的，因此卫星多普勒的同步观测能提高测站间相对定位的精度。

The main error sources of satellite Doppler positioning , ephemeris error and refraction error , are correlated between stations simultaneously tracking a satellite pass . So satellite Doppler simultaneous observations can improve the accuracy of relative positioning between stations .

在卫星多普勒定位中，抛弃了卫星的仰角低于10°的观测资料，因此，波迹弯曲不影响米级定位精度，可以忽略。

In the satellite doppler positioning , the observations are discarded when the elevation of the satellite is under ten degrees . Thus the buckled parts of wave path do not effect on the positioning accuracy for the order of meter magnitude and then can be neglected .
