便携式卫星图像接收终端的研究

随着经济技术的发展,现代战争是信息化与电子化的时代,军用手持终端日益受到军方的重视。根据手持终端接收卫星图像的高效性,提出了士兵在野外作战利用"北斗"定位系统获取当前三维信息,并且通过数传电台将三维信息发送回指挥中心同时通过指挥中心获取当前位置的卫星图像,从而准确获取当前作战地理形势。提出利用ARM+Linux架构,设计一款用于接收卫星图像的手持终端。其中基于S5PV210处理器和BDS定位模块为便携式卫星图像接收终端的核心。实现具有图像预览、无线数据传输和BDS定位等特点的硬件平台。

Research on the Portable Satellite Image Receiving Terminal

With the development of economy and technology, modern warfare has arrived the era of information and electronic technology, more and more attention to military handheld terminal has been received from the military. Ac-cording to the efficiency of the handheld terminal receiving the satellite image, the soldiers in combat with the "Big Dipper" positioning system is put forward to obtain the current three-dimensional information,and transmit 3D informa-tion back to the command center through the radio satellite image and get the current position through the command center,so as to obtain the current operational Geographic situation. Using ARM+Linux architecture,a hand-held termi-nal for receiving satellite images is designed,which based on S5PV210 processor and BDS positioning module for por-table satellite image receiving terminal core. The image preview, wireless data transmission and BDS positioning, such as the characteristics of the hardware platform are realized.
