【摘要】：月球重力场的研究是实施探月工程的前提和基础,但由于目前探月技术不足及月球特殊的物理环境,现有远月面重力场的精度难以保证探测器远月面登陆,而已在地球重力场研究方面得以成功实施的卫星跟踪卫星(SST)技术为解决这一难题提供了可能。本文通过模拟数据研究卫星跟踪卫星视线加速度确定月球重力场方法的可行性和可靠性,计算GRAIL卫星轨道参数下的月球全球重力异常。结果表明,卫星跟踪卫星视线加速度能较好地展现月球全球重力场的精细结构。
[Abstract]:The research of lunar gravity field is the premise and foundation of lunar exploration project. However, due to the lack of lunar exploration technology and the special physical environment of the moon, the precision of the present lunar gravity field is difficult to guarantee the landing of the probe on the far moon. The satellite tracking satellite SST, which has been successfully implemented in the study of the Earth's gravity field, provides the possibility to solve this problem. In this paper, the feasibility and reliability of the method for determining the lunar gravity field are studied by using the simulated data to study the acceleration of the line of sight of the satellite tracking satellite, and the global gravity anomaly of the moon under the orbit parameters of the GRAIL satellite is calculated. The results show that the acceleration of the line of sight of the satellite tracking satellite can well show the fine structure of the global gravity field of the moon.
