摘　　要：针对航天测量船标校经纬仪设备航向测量的局限性以及新装备的投入使用现状,分析了海上动态条件下静电陀螺监控器标定过程外界的影响因素,提出了静电陀螺监控器设备导航数据质量的分析方法。在此基础上,进行了试验数据的分析,通过与标校经纬仪测星计算的惯导航向误差比对,充分说明了该设备的良好性能,从而解决了测量船多云天气下标校经纬仪无法测星为惯导系统校准提供航向差的问题,实现了与标校经纬仪数据的互补,进而保障了航天测量船全天候海上测控的精度。In view of the limitations of TT＆C ship calibration theodolite equipment for heading measurement and the present situation of new equipments in use, this paper analyzes the external influence factors on electrostatic gyro monitor calibration under dynamic conditions, and puts forward the analysis method for electrostatic gyro monitor equipment navigation data quality. Based on these, the test data were analyzed and compared with the INS heading errors from the calibration theodolite＇s calculation by measuring star. It is shown that the equipment performance is high enough to solve the problem that the calibration theodolite of measurement ship can not provide heading difference for INS under cloudy weather, and realize the complementation with the calibration theodolite data, thus grantees the all-weather sea control precision of astronautic measurement ship.
