低成本组合导航系统的海上试验

Sea trial of low cost integrated navigation system

提出由罗经和多普勒计程仪构成自主式导航系统的方案,并对该导航方案的海上试验结果进行了分析.结果表明:多普勒计程仪可以测得较高精度的载体对地速度,从而有效地抑制了推位系统误差的积累,改善了导航定位精度.

The independence navigation method was presented,which consists of a gyrocompass and Doppler velocity log.The sea trial result of this method demonstrates that a doppler velocity log can accurately measure the ground referenced velocity, so that the gyrocompass/doppler systems can eliminate the accumulating errors of dead-reckoning, and improve navigation positioning accuracy.
