摘要

PROBLEM TO BE SOLVED: To perform highly precise position measurement and miniaturize a GPS position measuring device without necessitating a known point side GPS position measuring device (base station) and a relay station. ;SOLUTION: This GPS position measuring device is provided with an input part 24 used to input known point position information, an approximation part 28 which approximates a plurality of pseudo-distance information (propagation distance between GPS antenna 21 and a GPS satellite) obtained by a GPS receiver 22 at a known point by the least square approximation polynomial and outputs each coefficient as coefficient information, and a position measurement processing part 29 which obtains a plurality of pseudo-distances at an unknown point from the GPS receiver 22 and predicts a plurality of pseudo-distance predicted values predicting a plurality of pseudo-distances at a known point based on the coefficient information. The position measurement processing part 29 finds a position of an unknown point based on known point position information, a plurality of pseudo-distances at an unknown point, and a plurality of pseudo-distance predicting values.;COPYRIGHT: (C)2000,JPO
