针对交会对接任务追踪航天器从入轨到进入第一停泊点的交会过程,采用解析方法分析了交会过程的能耗问题。首先基于二体运动理论,根据导引终点的机械能、相位和偏心率约束分析了交会过程能耗的特点和计算方法,之后针对交会过程中大气阻力、地球非球形、入轨轨道面偏差和姿控因素,给出了对应的能耗估算方法,最后对空间站运营期间的交会对接任务给出了算例。 According to the rendezvous and docking task tracking spacecraft from the orbit into the first docking point of the rendezvous process, the use of analytical methods to analyze the energy consumption of the rendezvous process. Firstly, based on the theory of two body movement, the energy consumption characteristics and calculation method of the rendezvous are analyzed based on the mechanical energy, phase and eccentricity constraints of the guidance end point. Then, according to the air resistance, the non-spherical shape, The corresponding energy consumption estimation method is given. Finally, an example is given for the rendezvous and docking task during the operation of the space station.
