【摘要】 不同的卫星应用系统对轨道设计提出了不同的要求。文中提出的算法,能够自动生成卫星轨道参数,保证回归轨道卫星过顶地面某指定区域时,位于轨道的近地点,以满足卫星近地探测、侦察的一类仿真应用需求。该算法通过已知的近地点星下点坐标和随机的升交点经度确定出轨道面的空间位置;通过回归周期和近地点卫星高度确定出轨道形状和大小,进而求得满足条件的轨道方程。该算法在VC++中得到实现。文章最后给出了一个验证算法,通过输出数据和卫星星下点轨迹图验证了原算法。实践表明,文中提出的算法有效地支持了整体系统的仿真。更多还原

【Abstract】 Different satellite applications require different design of satellite orbit.This paper proposes an arithmetic which can generate random regressive orbits to ensure that the satellite is at its perigee when passing the given area of earth in order to meet the simulation needs of detection and recon at satellites’ perigee.The plane of the orbit is determined by sub satellite point of perigee and randomly generated longitude of ascending node;the shape and size of the orbit are determined by regressive period combining with the height of satellite at its perigee.This arithmetic is implemented in VC++.At last,a test arithmetic is given,which validates the arithmetic by data and sub-satellite track maps.Practice indicates that the arithmetic supports the system simulation application effectively.更多还原
