摘　　要：针对火星探测任务飞行距离远、通信时延长、器地交互码速率变化范围大的特点,提出了多模式变码率信息系统设计方法,确保了深空机动、制动捕获、进入下降与着陆(EDL)等关键飞行过程的关键遥测实时可靠下行,保障了地面科学有效决策,完成了“祝融号”火星车的无线授时和中继通信任务,对后续其他深空探测任务具有一定的借鉴与参考意义。In view of the characteristics of Mars exploration missions such as long flight distance,prolonged communication time,and large range of device-ground interaction code rate variation,a design method for the multimode variable rate information system is proposed to ensure the real-time and reliable downlink of the key telemetry during the key flight processes,e.g.,deep space maneuvering,brake capture,and entry,descent,and landing(EDL).The method is helpful to ensure the scientific and effective decision-making of the ground.With the method,the wireless timing and relay communication missions of the“Zhurong”Mars rover are successfully completed.The results have certain reference significance for subsequent deep space exploration missions.
