(57) ABSTRACT
An apparatus and method for displaying direction and position information of a portable terminal, wherein geographic position information of the portable terminal itself is displayed on the basis of a compass direction and a global positioning system (GPS). The portable communication apparatus comprises a base station for detecting and transmitting position information of the portable terminal corresponding to received GPS positioning information thereof, and a portable communication device including a sensor for detecting a true north direction of the portable terminal, the portable communication device transmitting the GPS positioning information of the portable terminal, which is received from at least one GPS satellite, to the base station, correcting an azimuth angle of the position information for display of the portable terminal, based on information of the true north direction of the portable terminal detected by the sensor, and displaying corrected position and direction information of the portable terminal.
