| 摘 要： | 文章介绍多谱勒计程仪测速精度的两种测定方法，实时法与准时法。在实法中，载体的航迹向与对地速度的真值均取自差分卫星定位仪。在准实时法中，利用差分卫星定位仪给出的地理坐标，根据中分纬度法、墨卡插法或波林法算得航迹向与对地速度的真值。两种方法所需的航向均取自于平台罗经。

| Abstract: | Two speed-precision measurement methods, real-time and quasi-real-time method, are described. For real-time method, the real-values of COG and SOG are got from DGPS. For quasi-real-time method, the real-values of COG and SOG are calculated by Mid-Latitude, Mercator or Bowring sailing method, the geographic coordinates obtained from DGPS are taken as the original datum of the three sailing methods. The bearings used by both two method are got from platform- gyrocompass. |
