1. A system for improving accuracy of a position correction data in a differential global positioning system (DGPS) through vehicle to vehicle (V2V) communication, comprising:

  • a global positioning system (GPS) reception unit configured to receive a GPS data from a satellite;

    a V2V communication unit configured to transmit and receive a DGPS correction data, while communicating with a road side unit (RSU) or other vehicles within a communication coverage;

    a sensor configured to detect a distance between the vehicle and another neighboring vehicle within the communication coverage;

    a multi-hop data processing unit configured to retransmit the DGPS correction data received from the RSU or the other vehicles within the communication coverage as multi-hop information, through the V2V communication unit, according to a control data; and

    a control unit configured to compare and calculate information output from the GPS reception unit, the V2V communication unit, and the sensor installed in the vehicle to calculate a correction position of the vehicle and correction accuracy, compare the calculated correction accuracy to a predetermined reference value, and control the multi-hop data processing unit based on a compared result to retransmit the DGPS correction data.
