PRECISE POSITIONING SYSTEM USING GLOBAL NAVIGATION SATELLITE SYSTEM AND A CORRESPONDING METHOD THEREOF

摘要

The present invention relates to a positioning system using a GNSS and a control method thereof. In a method for a terminal supporting a GNSS to perform location determination technology related with one embodiment of the present invention, the method includes the steps of: receiving first information from a first receiver; receiving second information from an international GNSS service (IGS); and outputting third information related with a position of the first receiver using the first information and the second information. The first receiver is one, and is a receiver which is not included in an IGS network related with the IGS. The first information may be information related with a radio wave which the first receiver receives from at least one satellite included in the GNSS.
