应用DGPS和平台罗经建立对地速度基准的方法研究

Method of Establishing Speed Reference with DGPS and Platform Gyrocompass

给出了一种海上试验时建立速度基准的方法,它是利用试验舰上已有的DGPS和平台罗经。这种方法在一定的海域和RBN/DGPS基准站几何尺度内可以满足测试对速度基准精度的要求。文中对各种对精度影响因素进行了定量分析,并给出了应用时的约束条件。

This paper presents a method of setting up a speed-reference during sea trial, which uses the DGPS and stabilized gyro compass onboard ship. In certain sea area and within the range of RBN/DGPS reference stations, it can meet the requirements of trial for speed reference accuracy. This paper makes a quantitative analysis on all kinds of factors that influence the accuracy and gives the applied restrictions.
