【摘要】 月球重力场是月球科学研究的重要部分,是进一步了解月球内部结构和构造的基础,也是我国探月计划“嫦娥工程”一个重要的科学研究内容.本文针对“嫦娥工程”,利用GSFC/NASA/USA的GEODYNII/SOLVE轨道分析软件,分析计算了利用单星跟踪数据恢复月球重力场的能力,同时模拟计算了双星跟踪数据在恢复月球重力场方面的能力,结合可能的工程环境我们对两种情况分别给出了30天、60天和90天的计算结果.计算表明双星相比于单星对月球重力场的中低阶位系数有比较显著的改善.更多还原

【Abstract】 The lunar gravity field is one of the key topics of lunar scientific research, and is the foundation to understand the inner structure and conformation of lunar, simultaneously it is an important research content of our lunar exploration projection “Chang’E". Aiming at “Chang’E" and making use of GEODYNII/SOLVE software from GSFC/NASA/USA, the capacity of lunar gravity field recovery from single and double lunar orbit satellites is computed at the same time, in each case the results from time spans of 30 days, 60 days, and 90 days are given considering the possible engineering environment. The computation shows that low and middle gravity field coefficients can be greatly improved in the case of double lunar satellites with respect to single lunar orbit satellite.更多还原
