The orbit characteristics of the target spacecraft and chaser spacecraft in space rendezvous and docking mission are analyzed. Firstly, the orbit characteristics of the target spacecraft are studied for the rendezvous and docking modes that the target spacecraft and the chaser spacecraft successively launch at the same site in certain interval. The orbit adjustments strategies of the target spacecraft and the precision requirement of the orbit prediction are discussed based on phase error characteristics of the orbit prediction. Then the orbit characteristics of chaser spacecraft during the ground control phase are analyzed. The characteristics of the Hohmann transfer orbit are studies, and the general transfer orbit is analyzed based on that. The relationship between the elements of the orbit design and terminal state of the ground control phase is analyzed, and the effect of orbit control error and the orbit prediction error on the terminal state of the ground control phase is studied, based on the analysis of the precision requirement for the orbit prediction, The analysis could be a reference to the design of the project.
