经纬仪测星法在测量船上的工程化应用研究

移动站缺少稳定的静基座，因此测控精度受到其不同设备间坐标转换的影响。通过分析经纬仪测星法理论和测量船设备组成、信息传输模式，提出将经纬仪测星法工程化应用于测量船上。经过深入的误差分析，其测量误差满足工程应用的需求，可以有效解决海上动态条件下航天测量船执行航天测控任务时因惯导台体不水平度导致的姿态误差以及因无线电设备大盘不水平度导致的测量误差，进一步提高测量船单位定轨能力，有效提升航天器测控精度。

Application of measuring star method with theodolite on TT&C ship

Through analysis of the theory of the measuring star method with theodolite,equipment composition of TT&C ship and information transmission mode,a measuring method with theodolite that can be applied to the TT&C ship is proposed.The error analysis shows that the measurement error of this method can meet the requirements of engineering application,and the measuring star method can effectively eliminate the attitude error caused by the unlevelness of intertial navigation platform and the measurement error caused by the unlevelness of the radio equipment on the sea.It improved the orbit determination ability of TT&C ship and the observe and control accuracy of areospacecrafts.
