Simulation of the Lunar Gravity Field Recovery Based on Lunar Solo and Bi‐Orbiters

Abstract

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's an important research content of Chinese lunar exploration mission “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 together, in each case the results from arc in time span of 30 days, 60 days, and 90 days are given combining with actual engineering environment. The computation shows that low and medium gravity field coefficients can be improved more remarkably in the case of double lunar satellites than single lunar orbit satellite
