Abstract: PURPOSE: A space informing system using a GPS(Global Positioning System) for a mobile phone and a method therefor are provided to add a space unit informing function, which is operated by only a time unit, to an informing system of the mobile phone by geographic information on space. CONSTITUTION: A plurality of GPSSs(GPS Satellites) successively transmit navigation message signals necessary for calculating position to a mobile phone(10) through a carrier. A base station including an ES(Earth Station), a WMS(Wide area Master Station), and a WRS(Wide area Reference Station) receives signals from the GPSSs, calculates and corrects a position with respect to a reference point, and transmits calculated position information to a GS(Geosynchronous Satellite). The GS transmits correction position error information about the base station to the mobile phone(10). The mobile phone(10) calculates the signals received from the GPSSs to obtain its current position information, re-corrects its current position information with reference to correction position error information to obtain accurate its current position information, and performs a corresponding operation when the obtained position is within a radius of a specific point.
