Mission Planning of Spacecraft Forced Fly-around and Implementation in Proprietary General Software
Targeting the increasingly complex space security situation and the demand for on-orbit service,a trajectory design method of spacecraft forced flyaround and the corresponding planning scheme in proprietary general software were proposed.It was assumed that the spacecraft used multi-pulse maneuvering to complete the forced flyaround missions and the task flow was analyzed first.Then the trajectory design schemes for forced flyaround mission were given.In addition,taking the target spacecraft orbit as circular or non-circular,the parameters of all target sequences in the over-all mission were given respectively.The position of each waypoint was calculated simultaneously.Finally,the trajectory planning of the forced flyaround mission was realized by using the proprietary general software,and the parameters were analyzed.The simulation results showed that the fuel con-sumption decreased with the increase of the task time and the maximum transfer flight angle of the entry section,and increased with the increase of the radius,number of points and time ratio of the flyaround section.
