<p>The present invention provides a differential global positioning system (DGPS) precise positioning system using an Internet network comprising: a DGPS reference station which is established on a predetermined area and communicates with a satellite navigation device; a user terminal which communicates with the satellite navigation device; and a server which is connected to the DGPS reference station through an Internet network, receives a received current GPS reception value from the satellite navigation device, compares the current GPS reception value with a pre-measured position value to generate a position compensation value, calibrates the current GPS reception value of the user terminal based on the generated position compensation value of the DGPS reference station closest to the user terminal to calculate a precise position value, and provides the calculated precise position value to the user terminal connected to the Internet network. Alternatively, the server is connected to the DGPS reference station through the Internet network, receives a received current GPS reception value from the satellite navigation device, calculates a current compensation compensation value based on the pre-measured position value, and provides the calculated compensation value to the user terminal connected to the Internet network such that the user terminal is enabled to calculate the precise position value.</p> |
