GPS GEODETIC CORRECTION DATA DISTRIBUTING SYSTEM, GPS GEODETIC DEVICE, AND MEDIUM RECORDING GPS GEODETIC PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a GPS geodetic correction data distributing system capable of being utilized in a wide range, a GPS geodetic device, and a medium recording a GPS geodetic program.;SOLUTION: This GPS geodetic correction data distributing system comprises a plurality of reference stations provided with GPS reception sections provided at predetermined positions and receiving the radio waves from a GPS satellite, distance calculation sections calculating the distances to the GPS satellite from the signals received by the GPS reception sections, and a means transferring the calculated distances to a base station and the base station provided with a means receiving the distance data transferred from the reference stations, a correction value calculation section calculating the correction values for individual reference stations based on the received distance data, and a transmitting means transmitting the correction data added with the state data of the GPS satellite to the calculated correction values to the reference stations via the down-circuit of a communication satellite on a time division basis.;COPYRIGHT: (C)2001,JPO
