推导了差分VLBI(ΔDOR)用于月球探测器定位的数学模型,利用嫦娥一号实测数据对探测器的位置和地球自转参数(ERP)同时进行了解算,并分析了ERP先验精度对定位精度的影响。
The mathematical model of differential VLBI (ΔDOR) for lunar probe location is deduced. The location of the detector and the Earth Rotation Parameter (ERP) are solved simultaneously with the measured data of Chang’e-1, and the relationship between the prior accuracy of ERP and the positioning accuracy Impact.
