Abstract:
1. A military wireless communication terminal for a soldier, comprising: a global positioning system receiver for receiving global positioning system signals and outputting location information of the terminal based on the received global positioning system signals; a terrestrial magnetism sensor for sensing azimuth of the terminal; a memory in which map information of an operating area is stored; a location transmitting unit for periodically transmitting terminal location information output from the global positioning system receiver; a radio communication unit for transmitting and receiving signals from a designated originating place; a military force location information processing unit for generating military force location information from a signal received from the radio communication unit; an absolute azimuth calculator for correcting sensed azimuth by the terrestrial magnetism sensor based on the terminal location information and outputting azimuth information; a map information reading unit for reading map information based on the terminal location information; a location information overlaying unit for overlaying the azimuth information, the military force location information on the read map information; a display for showing the read map information with the azimuth information and military force information overlaid; and a display screen rotating unit for dynamically rotating a displayed image such that true north is directed upward according to a user's instruction.
