A navigation system and a method for controlling the same wherein navigation functions are integrally mounted in a mobile communication terminal to enable to guide the travel of a mobile object in real time. A GPS receiving module is integrally mounted in the mobile communication terminal to receive navigation messages transmitted by the GPS satellites and to detect the position of the mobile object, terrestrial magnetic field is detected by a terrestrial magnetic field sensor module to detect an azimuth of the mobile object, an acceleration speed is detected by an acceleration speed sensor, and the travel speed of the mobile object is calculated by a speed detecting module using the acceleration speed thus detected, a current position of the mobile object is determined by an output signal from the GPS receiving module, the terrestrial magnetic field sensor module, and the speed detecting module, and the current position of the mobile object thus determined is matched to a map data stored in a map storage for display in a display unit.
