1YH-1星载超稳定晶振的频率稳定性的测试与分析显示文摘中国首个火星探测器'萤火1号'拟定在2011年发射升空。探测器上配备了一组(2个)超稳定晶体振荡器,该组晶体振荡器为X波段发射机提供频率标准,向地球发射下行信号。地面台站采用无线电开环多普勒和甚长基线干涉测量技术,对其进行通信、导航和跟踪。分析处理了'萤火1号'的超稳定晶体振荡器频率实验测试数据,确认晶体振荡器的频率稳定度约为1×10^(12),此结果可以作为火星探测器精密测定轨的有力支撑。王震 简念川 张素君 尚堃 高峰 王娜 平劲松 2011中国科学院上海天文台年刊2011,,1:4
2Results obtained by geodetic instruments of SELENE (KAGUYA)显示文摘Japanese lunar explorer SELENE (KAGUYA) was equipped with 14 instruments for various measurements of the Moon. Three of these instruments took geodetic measurements of the Moon. These were two sub-satellites and a laser altimeter. The main results obtained by the instruments are: (1) precise orbit determination with an accuracy of ten meters by Doppler and same-beam VLBI; (2) the first precise gravity fields on the lunar far side by 4-way Doppler measurements; (3) the first topography in latitudes higher than 86 degrees; (4) a global map of the gravity anomaly by using the global topography and the global gravity fields; (5) a global map of the lunar crustal thickness and (6) an illumination rate map in the north and south polar regions.KAWANO Nobuyuki VRAD/RSAT Team LALT Team 2010Science China(Physics,Mechanics & Astronomy)2010,53,12:1
