船舶光学经纬仪能够有效提升船舶导航的精确性，在复杂海况下光学经纬仪的测量存在依赖人工经验且精度低的问题。本文提出一种基于GPS载波相位差分技术结合双矢量定姿技术的光学经纬仪测量误差校准系统，通过实时测量获取船舶姿态角，并将其补偿到经纬仪测量结果中。设计系统整体结构，并对校准前后的测量误差进行对比。结果表明，校准后水平角和垂直角的误差均在10″以内，满足光学经纬仪测量误差校准的使用要求。
Ship optical theodolite can effectively improve the accuracy of ship navigation. In complex sea conditions, the measurement of optical theodolite relies on manual experience and has low accuracy. In this paper, an optical theodolite measurement error calibration system based on GPS carrier phase difference technology combined with double vector attitude determination technology is proposed. The ship attitude Angle is obtained by real-time measurement and compensated into the theodolite measurement results. The overall structure of the system is designed, and the measurement errors before and after calibration are compared. The results show that the errors of horizontal Angle and vertical right Angle after calibration are within 10 ", which meets the requirements of ship optical theodolite measurement error calibration.
