对萤火一号(YH-1)火星探测器有效载荷分系统设计进行了研究。根据YH-1科学探测任务、约束条件和特点,确定了探测器有效载荷配置为等离子体包、磁强计、掩星接收机和光学成像仪。各有效载荷采取单一工作模式,以简化控制。介绍了各有效载荷的控制和数据处理方式,以及有效载荷分系统的巡航段自检、火星空间环境探测、星星掩星实验、拍照、星地掩星实验等工作模式。对有效载荷的数据量进行了分析和设计。分析表明:YH-1火星探测器有效载荷的配置和设计能满足科学探测任务的需要,且具协调性、可操作性和资源利用充分性。
The firefly one (YH-1) Mars rover payload subsystem design was studied. According to the YH-1 scientific exploration mission, constraints and characteristics, the detector payload was configured as plasma package, magnetometer, occultation receiver and optical imager. Each payload takes a single mode of operation to simplify control. This paper introduces the control and data processing methods of each payload, as well as the working modes of cruise section self-test, Mars space environment detection, star occultation experiment, photographing and star-base occultation experiment in payload sub-system. The amount of payload data was analyzed and designed. The analysis shows that the configuration and design of the payload of the YH-1 Mars probe can meet the needs of scientific exploration tasks, and its coordination, operability and adequacy of resource utilization.
