In order to effectively deal with outburst of satellites at the end of service lifetime in a timely manner and aiming at preparation for satellite deorbiting,controlling and reducing unexpected hazards and adverse effects,strategy of deorbiting control under different conditions are analyzed based upon requirements of deorbiting control.Under the condition of limited fuel,a control strategy of multiple batch double pulse control referred to as "small step approaching" has been proposed.Under the condition of limited time,a control strategy of a short period of time and large quantity control referred to as "big step away" has been proposed,and the control strategy is verified by simulation.The results show that the "small step approaching" strategy can approach the tomb orbit as much as possible while the fuel is limited,and the "big step away" strategy allows the satellite to travel to the tomb orbit in a shorter period of time.This strategy applies to deorbiting control of Geostationary Earth Orbit (GEO) satellites at end-of-lifetime under abnormal circumstances.
