| 摘 要： | 舰艇真航向动态测量是利用航向角与方位角、舷角的关系来解算真航向。其中方位角的精确解算是保障动态检测精度的一个重要因素。本文从理论上分析了舰艇航行状态下纵横摇、GPS天线高度对GPS定位和方位角解算的影响及GPS与电子经纬仪安装位置不重合对方位角解算的影响，并进行了仿真分析，为方位角的精确解算提供了有力的理论依据。

| Abstract: | The true course is calculated by utilizing the relationship between heading angle, azimuth angle and board angle in research a- bout dynamic measurement of warship＇s true course. Under the circumstances, azimuth accurate calculating is one important factor on ensu- ring dynamic measurement accuracy. In theory, this paper analyses the impact of pitchroll, GPS antenna and the differ on location of GPS and the transit on azimuth measuring. Further more, this paper is carried on simulation. Importantly, this paper plays a solid theory founda- tion for azimuth accurate calculating. |
