  • 摘要: 针对载体运动状态的不同,选择合适的数据处理方法对齐GPS和全站仪两种测量设备测出数据的时间标记,并给出了误差分析公式和试验数据分析结果。结果表明,GPS与全站仪组合测量载体航向时,其静态精度可以达到30",动态精度可以达到2′。模型可以应用于船舶出航前以及进港时的导航设备标校,缩短其出航反应时间,引导其准确进港靠岸。
    Abstract: This paper is on carrier heading determination with GPS attitude determination (equipment) and TPSs. Time synchronization equipment for GPS and TPSs is designed with the help of GPS PPS. Linear interpolation and filtering methods for static data and cubic interpolation and filtering methods for dynamic data are applied. The precision error of the combination model of GPS and TPSs is analyzed. Experimental results show that the heading precision is 30″ in static condition, while 2′ in dynamic condition. The model can help the vessel correct the zero error of navigation devices, reduce the time to prepare to sail, and can conduct the vessel to make harbour.
