Figure 1

Definitions of coordinate systems employed in this paper. CIRF, ITRF, satellite body coordinate system, and satellite orbit coordinate system are denoted as O _E-X _CIRFY _CIRFZ _CIRF, O _E-X _ITRFY _ITRFZ _ITRF, O _S-X _BodyY _BodyZ _Body, and O _S-X _OrbitY _OrbitZ _Orbit, respectively. O _E is the geocenter, and O _S is the mass center of satellite.
