| 摘 要： | 文章分析了一种多普勒计程仪速度参照系统的误差源，该系统由差分卫星定位仪和平台罗经所组成。载体动力与航向控制不稳定、流速不稳定、流向不稳定、差分卫星定位仪的定位误差以及平台罗经的定向误差构成了测速参照系统的误差源。文章还给出了计算机仿真分析结果，从而可以了解速度参照系统的测速误差与主要误差源之间的依存关系。

| Abstract: | Error sources of the speed reference system for ADL are analyzed. The speed reference system is consisted of DGPS and a platform gyro. Unstable controls of the driving and steering of the vessel, instability of the ocean current velocity and directions, positioning error in the DGPS and direction error of the platform gyro are the error sources of the speed reference system. Computer simulation results are given. From these results, relations between the velocity measuring error of the reference system and main error sources can be obtained. |
