Abstract
A method of detecting a location of an opposing vehicle using Global Positioning System (GPS) information in which pieces of GPS raw data and pieces of GPS post-processing data of a driver's vehicle and of an opposing vehicle are received. It is determined using the received GPS post-processing data whether the opposing vehicle is a vehicle that has entered a predetermined range. If it is determined that the opposing vehicle is a vehicle that has entered the predetermined range, it is determined whether common data is present in the pieces of GPS raw data of the driver's vehicle and of the opposing vehicle by comparing the pieces of GPS raw data with each other. A degree of proximity to the opposing vehicle is using the common data in the pieces of GPS raw data of the driver's vehicle and the opposing vehicle.
