用于“萤火1号”火星轨道器的开环电测技术

Open loop tracking for Yinghuo-1 Mars Orbiter

中国首个火星探测器"萤火1号"计划于2011年和俄罗斯的火卫一采样探测器一道发射升空."萤火1号"将探测火星的空间环境,并验证深空导航测控与通信技术.与常规的火星探测任务不同,该探测器的轨道与位置测量主要利用天文甚长基线干涉测量技术、开环跟踪测量技术、差分单程测距测速技术、同波束干涉测量技术以及单程多普勒(Doppler)测速技术.

The 1st Chinese Mars Probe, Yinghuo-1, is planned to be launched in 2011, together with the Russian Phobos-Grunt landing mission. It will explore the space weather of Mars, and test the deep space communication and navigation equipment. Different from common deep space missions, astronomical Very Long Baseline Interferometry （VLBI）, open loop tracking like DOR/DOD, seam beam VLBI and one-way Doppler measurements, will be used to determine the spacecraft orbit and position.
