Outline
To counteract the influence of the Earth's non-spherical perturbation, Geostationary Earth Orbit (GEO) satellites must periodically execute longitude drift control to maintain their position in the east-west direction. East-west station-keeping is typically achieved via pulse ignition. During this process for geostationary orbit satellites, continuous telecommand must be sent, severely restricting payload applications closely coupled with satellite telecommand. This paper devises a decentralized control approach for the east-west station-keeping of GEO satellites, constructs a mathematical model, formulates control strategies and implementation details, and validates the control effectiveness using two distinct types of in-orbit satellites. This method efficiently exploits fragmented resources during payload task intervals, enhancing the availability of satellite tracking, telemetry, and telecontrol command resources.
