Abstract

Hill's equations of relative motion are applied to the problem of re-initialising the relative orbit of a cluster of Geosynchronous satellites which have deviated from their nominal relative orbits to such an extent that there exists an unacceptably high collision or telecommunication interference risk. A solution is presented for satellites possessing thruster capability along two perpendicular axes, the longitudinal direction and the latitudinal direction, which correspond to the burn directions used for East-West and North-South station keeping of GEO satellites. Absolute positional recovery with reference to a geocentric inertial frame is not considered. 1 Introduction The World Radio Administrative Conference of 1977 (WARC 77) was held to discuss direct broadcast satellite services. During the conference a plan for the allocation
