For the problem of long telecommunication signal transmitting time from the long distance in Mars exploration mission, the time spent of TT&C communication link rebuilt when interrupted is very large, the acquisition process design of near-Earth satellite and deep space spacecraft is analyzed, and emergency disposal acquisition process is proposed which can satisfy the requirement of sending telecommand immediately. Combined with the characteristics of uncoupling between uplink and downlink signals in the deep space spacecraft acquisition process, an emergency disposal is proposed in which the telecommand can be sent when the uplink acquisition process is accomplished under long-time delay condition, which can reduce the disposal time significantly. For the common malfunction of deep space TT&C equipment in practical application, the emergency disposal case of transmitter klystron malfunction is designed, with which the emergency disposal method is tested by local simulation and then successfully applied in the first Mars exploration mission. This case may give the references to the cooperative departments for malfunction disposal in deep space mission such as Mars exploration under long-time delay condition. [ABSTRACT FROM AUTHOR] |

针对火星探测任务中测控距离远、信号传输时延长、测控通信链路中断后重建双向链路时间 开销大的问题,分析了近地捕获与深空捕获的流程,提出了满足快速发令需求的应急处置捕获流程。 结合深空航天器捕获流程中上行与下行信号处理解耦合的特点,提出上行捕获流程完成即可发送遥 控指令进行应急处置,大幅缩短了处置用时。 以深空测控设备实际工作中常见的发射机速调管故障 为案例,对长时延条件下的测控系统捕获应急处置方法进行了模拟测试,并在首次火星探测任务中 成功应用。 此案例可作为火星探测等深空任务中测控链路异常故障处置时各单位协同工作的参考。 [ABSTRACT FROM AUTHOR] |
