哈萨克斯坦的通信卫星KAZSAT-2和我国的气象卫星FY-2D定点于同一位置,基于卫星安全因素,文章对两星轨道特性进行了长期分析,研究了影响两星距离计算的多种因素,建立了共位卫星的距离计算模型,给出了偏心率和倾角联合隔离的共位方法,并利用STK进行了仿真验证,对后续两星共位策略的制定有一定的参考意义。 Kazakhstan’s communications satellite KAZSAT-2 is located at the same location as China’s meteorological satellite FY-2D. Based on the satellite security factors, the article analyzes the characteristics of two-star orbit for a long time and studies various factors that affect the calculation of the distance between two stars. The distance calculation model of the co-located satellites is given. The co-location method of co-segregation with eccentricity and inclination is given. The STK is used to verify the co-location method, which is of certain reference significance for the formulation of the co-located two-star co-located strategy.
