Comparison Analyses on the 150×150 Lunar Gravity Field Models by gravity/topography Admittance, Correlation and Precision Orbit Determination



Comparison Analyses on the 150×150 Lunar Gravity Field Models by gravity/topography Admittance, Correlation and Precision Orbit Determination



Advances in Space Research 52(3): 512-520



We analyzed the 150 150 lunar gravity field models, LP150Q, GLGM-3 and SGM150, using the power spectrum on the lunar nearside and farside, the lunar global and localized gravity/topography admittance and correlation, and Chang E-2 precision orbit determination to investigate which model is a more effective tool to estimate geophysical parameters and determine the lunar satellite precision orbit. indicate that all gravity field models can be used to estimate the lunar geophysical parameters of the nearside of the Moon. However, SGM150 is better in such computation of the farside. Additionally, SGM150 is shown to be the most useful model for determining the lunar satellite orbit.
