A Comparison and Their Inertial Properties of Two Kinds of Geocentral Reference Systems

In this paper, the authors discussed the inertial properties of the geocentral stellar reference system (GSS) and the geocentral innate reference system (GIS), and pointed out that, in the region where, for an arbitrary point P, the distance from P to the Earth's centeris larger than 160 km ,GSS is better than GIS. However, to study some effects in the system of artificial satellite, it is better to choose a satellite stellar reference system whose center is located at the mass center of the artificial satellite.
