METHOD FOR CALCULATING THE POSITION OF A GPS RECEIVER, RECORDING MEDIUM FOR STORING A PROGRAM IMPLEMENTING THE METHOD, AND GPS RECEIVER

摘要

A method of calculating a position of a GPS receiver, a recording medium having recorded thereon a program for performing the method, and a GPS receiver are provided. The method of calculating a position of a GPS receiver includes the steps of causing a control unit to combine a plurality of satellite signals received through the use of a receiver unit and to create a plurality of satellite signal groups; selecting a low-error satellite signal group not including any GPS satellite signal causing a reflection error or including the GPS satellite signal causing a reflection error as little as possible by the use of pseudoranges based on the GPS satellite signals included in the satellite signal groups; detecting the GPS satellite signal not included in the low-error satellite signal group as a reflected satellite signal; and calculating a positional coordinate of the GPS receiver by the use of the GPS satellite signals other than the reflected satellite signal. As a result, by excluding the GPS satellite causing a reflection error to remove the reflection error, it is possible to more accurately calculate the current position of the GPS receiver.
