| Abstract | 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。 |
| Other Abstract | As an important milestone in the exploration Of Mars in China, "YingHuo-1" , Chinese first Mars probe, is planned to be launched in 2011. The kernel payload of "YingHuo-1" is Ultra Stable Oscillator (USO) which provides frequency standard and transmits downlink Signal. The ground-based radio Open-Loop-DoppIer technology and VLBI system will be used to receive radio signal and support communication, navigation and tracking. In this article, the experimental data of YingHuo- 1 's USO is presented. Results show that the frequency stability Of USO is about 1 × 10^(-12) which can support real-time precise orbit determination. |
