The early warning of single satellite is a necessary process and an important part of the early warning system. As forepart warning, it is very important to give trajectory course information early to radar system for putting a tail on the missile. In this paper, based on the missile momentum equation, taking into account the basic physics’ restrictions in missile’s manufacture and flight, a new method is established to obtain the trajectory course by early warning of single geosynchronous satellite, without prior information supporting. The corresponding simulation computation has been carried on and shows the method’s correctness and value in this paper.
