Mathematical Preliminaries
摘要
The five coordinate systems used in the studies are: the selenocentric inertial (Moon-centered), the selenocentric local (Moon-fixed), the selenocentric platform, the guidance and the body coordinate systems. Note that the Y-axis completes the right-handed triad in all these coordinate systems [1]. In this work, the subscripts or superscripts L, P, G, B, I will indicate the local, platform, guidance, body and inertial systems respectively. These systems are depicted in Figures 4.1, 4.2, 4.3.
