【摘要】：月球重力場的研究是實(shí)施探月工程的前提和基礎(chǔ),但由于目前探月技術(shù)不足及月球特殊的物理環(huán)境,現(xiàn)有遠(yuǎn)月面重力場的精度難以保證探測器遠(yuǎn)月面登陸,而已在地球重力場研究方面得以成功實(shí)施的衛(wèi)星跟蹤衛(wèi)星(SST)技術(shù)為解決這一難題提供了可能。本文通過模擬數(shù)據(jù)研究衛(wèi)星跟蹤衛(wèi)星視線加速度確定月球重力場方法的可行性和可靠性,計(jì)算GRAIL衛(wèi)星軌道參數(shù)下的月球全球重力異常。結(jié)果表明,衛(wèi)星跟蹤衛(wèi)星視線加速度能較好地展現(xiàn)月球全球重力場的精細(xì)結(jié)構(gòu)。
[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.
