摘　　要：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。The energy consumption of chasing spacecraft during the rendezvous phase, which starts from orbit injection to the first perching point, is derived by analytical method. Firstly, the characteristics and the estimating method of the energy consumption based on two-body theory is provided, with the restriction of the mechanical energy, phase angle and orbit eccentricity. Then, the perturbation factors during the rendezvous phase, such as atmospheric drag and oblateness of the Earth, attitude control, as well as the orbit injection errors, are taken into account, and the corresponding estimat- ing method is also presented. Finally, a calculation example is provided for the R＆D of the space station.
