METHOD AND SYSTEM FOR CONFIGURING ERROR CORRECTION DATA BASE FOR MEASURING GPS POSITIONING COORDINATE AND METHOD AND SYSTEM FOR CORRECTING MEASUREMENT ERROR OF GPS POSITIONING COORDINATE
METHOD AND SYSTEM FOR CONFIGURING ERROR CORRECTION DATA BASE FOR MEASURING GPS POSITIONING COORDINATE AND METHOD AND SYSTEM FOR CORRECTING MEASUREMENT ERROR OF GPS POSITIONING COORDINATE
PROBLEM TO BE SOLVED: To realize a more accurate measurement of positioning coordinate by employing an existing system, e.g. DGPS(differential GPS) in combination at the time of measuring the coordinate value at a fixed point using GPS. ;SOLUTION: The inventive system comprises means 35A for collecting the difference between the coordinate value at a receiving point determined by analyzing radio waves received from a plurality of GPS satellites and the accurate actual coordinate value at the receiving point as an error correction data at a specified time period, means 35B for storing an error collection data collected by the collecting means 35A in an error collection data holding means 31a while being associated with the collection time thereof in sidereal day wherein the error correction data storing means 35B stores the error correction data at each time of one sidereal day in the error collection data holding means 31a.;COPYRIGHT: (C)1999,JPO
