船用摇摆试验台外环轴的方向标定

摘要

船用摇摆试验台外环轴的方向标定，属于难度很大的超短基线观测技术。本文探讨了其中的几个关键技术，叙述了方位角的传递与观测纲要，分析了方位角的传递误差，为实时精确测量舰船摇摆的姿态参数，对船载仪器设备动态性能试验提供准确数据，建立了基准方向。%The method of calibrating direction of the outer ring in test swing platform system based on technology of ultra-short base-line surveying.In this paper we discuss some key technique of the method:surveying schema and transferring azimuth;Deviations of transferring azimuth.Our ultimate aim is establishing a base direction of the test swing platform in order to survey precise real -time parameters of the swing platform and provide accurate data of dynamic performance test of marine equipment.
