solve the problem of dynamic calibration for gyro navigation system, the high precision carrier phase GPS receiver is a-dopted to measure vessel heading. At the same time, the heading information of gyrocompass is captured in synchronization. Gyrocompass heading data is compared with GPS heading data in the data processing centre for gyrocompass calibration. The heading accuracy of dynamic calibration system is compared with INS. The dynamic experiment result shows that the heading accuracy of dynamic calibration system can satisfy the requirement for gyro navigation equipment calibration.%针对罗经等惯性导航装备的动态标校问题,采用高精度的GPS载波相位测姿定位接收机对舰船真实航向信息进行实时动态测量,同时对罗经等导航设备的航向信息进行同步采集；通过对传送到标校信息处理中心的采集数据进行分析比对,实现对陀螺导航设备动态性能的评估、测试和标校；通过与某型惯性导航系统进行海上航向精度对比试验,系统航向动态测量精度与惯性导航系统精度相当,可满足罗经等中低精度导航设备的动态标校需求.
