摘要
火星科学实验室任务测控通信与导航技术代表了目前该领域的最新方向。在结合火星科学实验室任务特点并对其对测控通信系统设计性能、导航性能进行分析的基础上,以未来的自主火星探测以及火星采样返回任务为潜在工程应用目标,结合我国月球和深空探测测控系统的现状,梳理了我国未来自主火星探测中火星中继网络、火星探测器精密定轨,以及火星大气进入、下降和着陆过程中的信号检测与估计等关键技术。该研究对后续的自主火星探测测控通信系统的设计具有一定的参考价值,对推进我国深空探测测控系统的发展具有重要意义。
The TT＆C （Tracking, Telemetry and Command） and navigation technologies of MSL （Mars Science Laboratory） represent the new direction of the field. Based on analysis of the characteristics of Mars missions, study was done on the characteristics of TT^C and navigation. Taking future Mars exploration and Mars sample return as the objective of potential project application and based on the current state of TT^C systems in lunar and deep space exploration, a comprehensive analysis is given on key technologies of Mars TT^C and navigation, such as Mars re- lay, precision orbit determination and detection and estimation of signals in Mars entry descant and landing. The results of research are of high value to construction of TT＆C systems for China＇s Mars exploration, and it is of great significance for development of deep space TT＆C systems.
