摘　　要：用于深空测控任务的干涉测量天线的高精度站址测量对于深空航天器的高精度导航具有重要意义。为此,结合国内外对干涉测量天线高精度站址测量技术的研究、试验及成果,对2种站址测量方法——测地VLBI(Very Long Baseline Interferometry,甚长基线干涉测量)方法和归心测量方法的原理、现状进行了总结与比较:测地VLBI方法最为直接有效,且测量精度高;归心测量方法能反映参考点的本地变化,可提供站址初值,且便于连续监测;2种方法优势互补。在此基础上,对高精度站址测量技术未来的发展方向进行了展望。该领域技术的发展现状对我国深空测控网的后续建设具有重要的借鉴意义。Determination of the precise station position of interferometry antennas for deep space tracking has great significance to deep space spacecraft navigation. Following a review of research, experiments, and results on station position determination home and abroad, two methods, i. e. geodetic Very Long Baseline Interferometry （VLBI） method and local survey method, are compared with emphasis on their principle and applications. Geodetic VLBI is the most effective method and can achieve very high precision while local survey can continuously reflect local posi-tion changes conveniently, which usually provides initial position for a newly-built station. Therefore, they have complementary advantages. On this ba sis , the prospect for development of station position determination of interfer-ometry antennas is studied. The overview and prospect provide an important reference for the follow-up construction of China’s deep space network.
