| 摘 要： | 利用中国VLBI网无线电天线和数字信号采集系统跟踪测量了欧洲航天局的＂火星快车＂（MEX）探测器,并研发了相应的三程多普勒信号提取算法和软件。对探测器8.4GHz下行载波1s采样的最终结果显示,多普勒数据随机噪声为1mm/s,这些数据已成功应用于对火星探测器的轨道确定。

| Abstract: | Using the radio telescopes in Chinese VLBI Net (CVN) and sampling board, we have developed algorithms that extract three-way Doppler information from the radio tracking data of Mars Express (MEX)-a Martian probe that belongs to European Space Agency (ESA). Our latest results indicate that Doppler residuals of three-way Doppler are about 1mm/s in 1s integration time, relative to an 8.4GHz carrier. Three-way Doppler data have been used in the orbit determination of Mars Express. |
