摘要
为确保船舶航行安全,利用北斗二代卫星导航技术,设计船载定位终端.该终端以S3C2440ARM处理器和Windows CE 6.0嵌入式系统为核心,以外围电路为辅,采用最小二乘算法,实现船舶的导航定位.通过MATLAB软件对可见卫星数目和水平精度因子进行计算和分析,论证方案的可行性和可靠性,进一步推动北斗船载终端在航行中的应用.
In order to guarantee the ship navigation safety, the shipborne positioning terminal was designed based on the Beidou-2 satellite navigation system. The S3C2440 ARM processor and the Windows CE 6.0 embedded system were taken as the core parts of the terminal which is assisted by the peripheral circuit. And the least square algorithm was used to realize the ship navigation and positioning. Then, the numbers of visible satellites and horizontal dilution of precision were calculated and analyzed by using the MATLAB software. The results show that the design is feasible and reliable, which can further promote the application of the Beidou shipborne terminal in the ship navigation.
