摘　　要：基于应急轨道的概念与特点,分析应急对地侦察任务对轨道的需求,并依据光照条件和降低星载相机复杂性的需求选择太阳同步圆轨道,并分析轨道响应时间、重访频率、空间分辨率、单次覆盖持续时间和覆盖范围与轨道高度的关系;最后,综合分析认为轨道高度为300km的太阳同步圆轨道可较好地满足应急对地侦察任务的需求。On the basis of concepts and characteristics of emergence orbit, analyze the requirements of emergency-earth-reconnaissance task; chose sun synchronous round orbit according to light application conditions and requirements of reducing the complex of space-based camera; analyze orbit response time, revisiting frequency, spatial resolution, duration of signal coverage, coverage area, orbit altitude and their relations. Then, comprehensive analysis suggests that sun synchronous round orbit whose altitude is 300km can meet the requirements of emergency earth reconnaissance tasks.
