Satellite-Ground Pointing Properties of Constellation with Regressive Common Ground Track

Satellite constellations have important applications in communication, navigation, remote sensing, scientific experiments and other fields. This paper presents a new analysis for satellite-ground pointing properties of constellation with regressive common ground track. This analysis employs the fusion of regressive orbit and common ground track. In this paper, the satellite-ground pointing properties of constellation with regressive common ground track is investigated using "access and link" simulation. First, build data links between satellites and ground stations. Second, according to the dynamics of satellite motion and Earth rotation, combined with communication constraints such as elevation Angle, the access analysis of satellite and ground station is constructed. Third, on the basis of access analysis, link planning is carried out. The period property, access time property and pointing path planning property are weighed based on a set of simulation cases. The analysis of the characteristics of constellation with regressive common ground track provides important reference for engineering application.
