用VLBI跟踪数据确定CE-2环月段轨道的研究

Mission Orbit Determination and Analysis of CE-2 with VLBI

利用自主开发的深空探测器定轨软件,用我国嫦娥二号(CE-2)探月卫星环月段VLBI观测数据,解算了CE-2环月段轨道,并从观测数据残差、重叠弧段比较、外符合对比三个方面分析了VLBI用于CE-2环月段定轨的精度。

With the copyrighted software for the orbit determination of deep space probe which was developed independently,the mission orbit of Chang＇E-2 is determined using the VLBI delay and delay rate tracking data of CE-2. The orbit accuracy is assessed with the post residual of VLBI delay and delay rate,the 6 hours of overlap differences of the dynamic orbit and the difference between the dynamic orbit and the precise orbit computed by Shanghai Astronomical Observatory.
