结合快响卫星在实际任务中的应用背景,研究了响应时间约束中的敏捷轨道设计方法。首先,根据快速响应卫星的发射点和目标点的位置关系,结合快速响应时间约束,得出了响应时间与轨道高度的不等式关系;其次,针对常见的圆形轨道,根据球面三角形公式,构建了敏捷轨道轨道周期、轨道倾角、升交点赤经的解析设计方法;最后,结合STK软件的典型任务仿真,分别设计了当圈响应与第3圈响应的两类敏捷轨道,使卫星分别在入轨10min与200min时星下点通过目标区域,验证了方法的可行性、易操作性和实用性。
Combined with the application background of fast satellites in practical tasks, the design method of agile orbit in response time constraints is studied. Firstly, according to the position relationship between the launch point and the target point of the rapid response satellite, combined with the fast response time constraints, the inequality relation between the response time and the orbit height is obtained. Secondly, for the common circular orbit, according to the spherical triangle formula, Finally, combined with the typical mission simulation of STK software, two types of agile orbits, respectively, the response of the ring and the response of the third ring are designed respectively, so that the satellites are in orbit The points under the stars passed the target area at 10min and 200min, which verified the feasibility, practicability and practicability of the method.
