“…The definition of N-hour repeating equatorial orbit is: starting from the current longitude of subsatellite point, the satellite returns to this longitude for the first time after N hours [5]. Therefore, the design process of a retrograde N-hour repeating MEERO is given below [6].…”

“…On the basis of previous work of authors [5] [6], this paper introduces a new design scheme of GEO objects monitoring satellite system based on the concept of 180° inclination retrograde Medium Earth Equatorial Repeating Orbit (MEERO). This satellite system could achieve a 2-hour revisit capability of GEO belt objects by a single satellite, with a maximum spatial resolution better than 2m based on the current optical remote sensing payload technology.…”

The observing, tracking, and monitoring of space debris in Geostationary Orbit (GEO) belt have become one of the key issues in space situational awareness. It is impossible to achieve observation of GEO belt by a single ground station, since the GEO objects are relatively stationary with respect to the Earth's surface. In this paper, a new design scheme of GEO debris monitoring satellite system is proposed based on the concept of 180° inclination retrograde equatorial orbit. This satellite system can achieve a two-hour revisit capability of GEO belt, with a spatial resolution better than 2 m for 0° GEO objects based on the current optical remote sensing payload technology. The relationships among orbital elements, spatial resolution performance, and con-stellation size are analyzed and evaluated.
