摘要
文章简要介绍了同波束甚长基线干涉(VLBI)观测法和相位时延推导法,报道了上海-乌鲁木齐基线的误差为0.0005m的差分相位时延的观测结果,介绍了"萤火1号"和"福布斯"探测器的同波束VLBI观测技术及正在研究的相位时延推定新方法,展望了超高精度的VLBI相位时延在中国深空探测中的应用前景.
This paper reviews the methods of same-beam very long baseline interferometry （VLBI） observations and the estimation of high-accuracy phase delay. We report the observation results of the phase delay on the Shanghai-Urumqi baseline, with a measurement error as small as 0. 0005m. We also describe the same-beam VLBI observation teechniques for the Chinese Yinghuo-1 and Russian Phobos-Grunt spacecrafts, and a new method to estimate phase delay. Prospective applications in China＇s future missions are surveyed.
