Digi-PS positioning method and system using wireless call network

摘要

The present invention relates to a GPS, which is a positioning device using satellites, and to a radio call network that can precisely take a position measurement value required by a navigation system by positioning a moving object or a specific point using a GPS and a GPS. It is an object of the present invention to provide a DGPS positioning method and a system thereof.;In order to achieve the above object, the present invention compares the position value of the reference station itself obtained from the base station GPS receiver with the reference value that has been actually registered and registered, and generates the position correction signal of the DGPS reference station. The base station of the wireless call network transmits the subscriber's position value in the subscriber GPS receiver connected to the wireless call terminal by transmitting it to the subscriber's wireless call terminal in the base station's administration area through the wireless channel of the wireless call network.
