针对综合导航系统信息种类繁多,测试困难的特点,以Labview为软件开发平台设计了舰船综合导航系统多通道数据采集及精度评定系统。根据系统信息输出协议,设计了系统数据解码和误码检测算法,实现了综合导航系统输出数据的实时、准确采集。针对综合导航系统各分系统的信息种类和误差特性不同,利用采集的GPS卫星导航设备的速度、位置输出为参考,以MS860测姿系统的输出为姿态参考,设计了惯导系统、平台罗经等自主性导航设备精度评定算法,对其精度进行评定。系统成功应用于某新型惯导的精度评定海试试验。
To solve the difficulties of integrated navigation system test, a multi-channel data acquisition and precision evaluation system for integrated navigation system is developed using the Labview. The algorithm is designed to acquire the system data timely. According to the different characteristic of the subsystem of the integrated navigation system, the precision evaluation algorithm for INS, platform compass and such inertial system is designed refered to the positions and velocities of GPS and attitudes of MS860. the test and precision evaluation system is applied to a novel INS test on sea.
