Introduction to American Approaching Operation Satellite MiTEx in Geostationary Orbit and Its Inspiration

MiTEx（Micro-satellite Technology Experiment） is an American satellite deployed on a quasi-geosynchronous orbit, which includes MiTEx-A and MiTEx-B. The mission of MiTEx is to conduct approaching operations to the geostationary orbit satellites. In the paper, the develop- ment situations of MiTEx plan are presented. According to the orbit elements that can be ac- quired currently, the whole flight process of MiTEx is deeply studied, the flight stages of MiTEx-A and MiTEx-B satellite are partitioned, the flight tracks of each stage described, and the important track data provided. The flight mission of MiTEx satellites are analyzed. On the basis of flight mission analysis, and incombination with the literatures about MiTEx, the probable ca- pabilities of MiTEx are conjectured. Based on the MiTEx mission, inspirations for the applica- tions and required key technologies of approaching operations on non-cooperative GEO targets are proposed.
