摘　　要：立体测绘卫星对星下点轨迹要求较高，轨道维持频繁。目前轨控策略是载荷需在轨道维持24小时之后才能工作，载荷使用效率低；同时，轨道维持需要4个测控弧段，占用测控资源多。本文提出了一种缩短卫星控制窗口的快速轨道维持策略，并从星上实现和满足用户需求两方面论证了该策略的可行性。The stereo mapping satellite imposes strict requirements on the track of sub - satellite points, and the orbit ma- intenance is frequently carried out. According to the orbit control strategy at present, satellite payloads will not start to work until 24 hours after the orbit maintenance which requires four measurement and control segments and occupy much TT＆C （ Telemetry, Tracking ＆ Control） resource. In this paper, a rapid orbit maintenance strategy which can shorten the satellite control window is put forward, and the feasibility of this strategy is demonstrated in terms of satellite realization and fulfillment of user requirements.
