摘要
对萤火一号(YH-1)火星探测器星星掩星接收机设计实现进行了研究。给出星星掩星探测原理和设计的掩星接收机。性能和地面仿真测试结果表明:掩星接收机各项性能指标优良,灵敏度高,满足中俄联合火星电离层无线电掩星观测试验高精度的探测需求。
The design and realization of satellite-satellite radio occultation receiver on YH-1 Mars probe were studied in this paper. The principle of satellite-satellite radio occultation and the receiver designed were given out. The performance test result and obscuration event simulation showed that the receiver had excellent performances and high sensitivity, which met the requirement of high accuracy measurement in ionosphere satellite-satellite radio occultation of China-Russia joint Mars exploration.
