应用于复杂电磁环境下的一种新型船艇导航系统

A New Watercraft Navigation System Applied in Complex Electromagnetic Environment

复杂的电磁环境是未来信息化战场最突出的特征,这样的环境将会干扰现有依靠无线电波进行工作的导航系统。为有效解决船艇在复杂电磁环境下的导航问题,提出了一种以陆标定位为基础的新型船艇导航系统。系统通过高清度摄像机和磁航向传感器获取观测物标数据,经过计算机解算,将位置信息显示到电子海图上。海上试验情况表明,与传统的陆标定位相比,本系统在定位时间、定位精度等方面具有明显的优越性,完全满足军事航海的要求,具有良好的军事效益。

Complex electromagnetic environment is the most outstanding characteristic of future infonnatization battle field, and it will interfere with the existing navigation system depending on the radio waves. In order to solve the problem of the navigation under the complex electromagnetic environment effectively, a new watercraft navigation system based on terrestrial fixing is proposed. The system captures the data of positioning objects through high definition camcorders and magnetic heading sensors, and then displays the information on the elec- tronic chart after computer processing. The trial on the sea shows that the system goes far beyond the traditional terrestrial fixing in the aspect of time and accuracy. It can completely meet the requirement of military navigation and will definitely have good benefit.
