Study on Ship Orientation System Based on Windows CE System

简述了以GPS载波相位解算船舶定向的原理和实现方法。在利用双差模型求解船舶姿态角的过程中,通过一种快速求解整周模糊度的方法,缩短了初始整周模糊度的求解时间;并在此基础上,构建了基于ARM的双GPS接收机船舶定向装置的嵌入式硬件平台和软件系统。最后,通过静态和伪动态实验证实了本系统的可行性。

This paper introduces the principle and realization of ship’s orientation determination by using GPS carrier phase technologies.In the computing process where ship’s attitude angles is calculated by using the double-difference model,a fast ambiguity resolution（AR） method is applied,so that calculating time of the original integer ambiguity is reduced significantly.Based on above theoretical and methodological considerations,the hardware platform and software of embedded ship orientation system,in which double GPS receivers is based on ARM,are established.At last,the feasibility of the orientation system is verified with both static experiment and pseudo-dynamic experiment.
