System for determining position of mobile communication terminal and method thereof

A system for determining the position of a mobile terminal, comprising:

• a mobile terminal, in which a GPS engine is loaded;
• a signal measuring apparatus for measuring the reception angle and the delay time of a mobile communication signal;
• a GPS receiver for receiving the transmission signal of a GPS satellite and measuring the error correction data and the GPS satellite data of a GPS satellite signal;
• a pseudo range corrector for correcting the pseudo range measured by the GPS engine using the error correction data;
• a first position calculator for calculating the position of the mobile terminal by the corrected pseudo range;
• a second position calculator for calculating the position of the mobile terminal using the reception angle and the delay time of the mobile communication signal;
• and
• a position calculation filter for calculating the optimal position of the mobile terminal on the basis of the calculation results of the first and second position calculators.
