Abstract
In a position measuring method, GPS ranging data obtained at a reference stationand an observation stationis inputted to four solution calculating sections, RTK solutions such as a fix solution at the observation stationare calculated in the solution calculating sectionsaccording to the RTK system, and the RTK solutions are inputted to a solution obtaining unit. Further, it is decided whether or not the RTK solutions include multiple fix solutions. When it is decided that the RTK solutions include multiple fix solutions, deviations between the fix solutions are determined and it is decided whether or not the deviations exceed an allowable value. When it is decided that none of the deviations exceed the allowable value, predetermined arithmetic processing is performed on the fix solutions to obtain a normal fix solution. Moreover, the solution calculating sections are sequentially restarted at predetermined time intervals.
