目前航天器的三程多普勒跟踪技术已经在深空探测的控制与导航领域起到了重要作用。利用包含了对局部洛伦兹不变性(LLI)以及局部位置不变性(LPI)原理有破坏的三程多普勒跟踪理论,研究分析了“火星快车”(MEX)三程多普勒跟踪数据的残差。这些多普勒观测于2009年8月7日和8日进行,利用了欧洲航天局(ESA)在澳大利亚新诺舍(New Norcia)的上行站和三个分别在中国上海、昆明以及乌鲁木齐的下行站。我们发现,这些观测结果给出的LLI上限在10-2的量级。但由于各观测站本身对频率测量的精度有限,这些数据并不适合于检验LPI。
The current spacecraft’s three-way Doppler tracking technology has played an important role in the control and navigation of deep space exploration. Based on the three-way Doppler tracking theory, which contains the principle of local Lorentz invariance (LLI) and local location invariance (LPI), the effects of “Mars Express” (MEX) Tracking data residuals. These Doppler observations took place on August 7 and August 8, 2009, taking advantage of the European Space Agency (ESA) ascent station in New Norcia, Australia and three downstream stations in Shanghai, Kunming and Urumqi, China station. We find that these observations give LLI caps on the order of 10-2. However, due to the limited accuracy of frequency measurements at each station, these data are not suitable for testing LPI.
