Abstract
In light of the problems of too long orbit decay time and collision risk in LEO (low earth orbit)satellite deorbit,an active deorbit disposal strategy based on orbit elevation is pro-posed.In this strategy,the satellite orbit is elevated to safe orbit by several Homan orbital trans-fer.The proposed coordination strategy of"energy maintenance,propellant maintenance,mea-surement and control maintenance"meets the needs of safe operation,emergency treatment and scientific test through the adj ustment of satellite attitude and the angular velocity after deorbit. The test results of a retired LEO satellite show that the active deorbit disposal strategy is reason-able and effective,and satellite data on orbit show that the satellite spins steadily around the main axis of inertia with adequate energy and stable tracking control.The active deorbit disposal strategy proposed in the paper provides useful references for deorbit disposal of LEO satellites in higher orbit.关键词
