In this research, novel orbit determination system using VLBI (Very Long Baseline Interferometry) is suggested, in which satellites on low earth orbits are observed by clustered small-size ground stations. Firstly, LEO satellites are observed by using existing radio interferometer, and efficient technique of collecting and analyzing observations are studied. Secondly, constructing a small-size ground station, the ability of receiving radio signals is evaluated by analyzing the real observations. Through these works, a basic technology toward a future networked observation system is established.

本研究提出了一种新的VLBI定轨系统，该系统利用小型地面站集群观测低轨卫星。首先，利用现有的射电干涉仪对低轨卫星进行了观测，研究了有效的观测数据采集和分析技术。其次，构建了一个小型地面站，通过对真实的观测数据的分析，对接收无线电信号的能力进行了评估。通过这些工作，为未来的网络化观测系统奠定了基础。
