Abstract:
According to the present invention, a GPS reference station generates and transmits compensation information on GPS deviations for each wireless AP, and a user terminal recognizes and uses the information to compensate for information received through a GPS receiver of the user terminal, in order to deliver precise GPS performance. In particular, a precise GPS system of the present invention comprises: a GPS reference station for receiving a first satellite signal from a GPS satellite to generate navigation compensation information on a wireless AP, and transmitting the generated navigation compensation information to a wireless AP; a wireless AP for receiving the navigation compensation information from the GPS reference station, and transmitting the information to a user terminal; and a user terminal for receiving a second satellite signal from a GPS satellite, recognizing the navigation compensation information from the wireless AP, and generating precise user position information based on the second satellite signal and the navigation compensation information.
Abstract:
PURPOSE: A multiple navigation signal receiving method and a receiver for GNSS are provided to increase data processing speed and efficiency by processing data with high accuracy. CONSTITUTION: A multiple positioning signal receiver of a global positioning system comprises a plurality of receivers(110,120,130), a data processing block(140), and file generators(160,170,180). A plurality of receivers receives a navigational data signal. The data processing block extracts data integrity. The data processing block determines the priority of the data integrity. The data processing block extracts GPS data by priority. The file generators generate an RINEX file.
