摘　　要：针对地球静止轨道(GEO)卫星全天时全天候高精度的监测需求,考虑传统甚长基线干涉(VLBI)测站高成本、高投入和GEO卫星专用观测时段有限等制约条件,研发了简易型VLBI观测系统,并组建了包括上海、都匀和乌鲁木齐三站的微型VLBI网(micro VLBI network,MVN),开展了并置站测试以及对GEO卫星亚太6C的连续监测,并评估了当前MVN的观测能力。结果表明MVN扣除系统差后的单站接收精度为2 ns,各基线观测时延拟后残差约几纳秒,GEO目标实测位置精度为百米级(内外符精度分别约100 m和400 m)。不同于传统VLBI和其他GEO监测手段,MVN还具备全天时、全天候、低造价、易布设及易推广等特点,充分表明了其在GEO卫星监测领域的应用价值。According to the requirements of all-time,all-weather and high precision geostationary orbit(GEO)satellite monitoring,a simple very long baseline interferometry(VLBI)observing system was developed and a micro VLBI network(MVN)including Shanghai,Duyun and Urumqi was built.Debugging in collocated stations was performed and GEO satellite named as Apstar6 C was monitored by MVN,whose observing capability was evaluated.The receiving accuracy of single station without systematic errors was 2 ns.The results show that the post-fit residuals of different baselines are about several nanoseconds.Moreover,the accuracy of observed GEO satellite orbit is in the level of 100 m(internal and external accuracy of about 100 m and 400 m respectively).Unlike traditional VLBI or other GEO monitoring techniques,MVN has features including all-time,all-weather,low cost,easy deployment and convenient marketing,showing its great application value in the field of GEO satellite monitoring.
