PROBLEM TO BE SOLVED: To provide a moving speed measuring instrument and a system therefor capable of eliminating determination for an integer bias, and capable of measuring a relative speed of a moving station with respect to a reference station precisely. SOLUTION: Carrier phase information about each satellite and relatively rough positions of the reference station and the moving station are found respectively in the both stations, a coefficient (speed conversion coefficient) between a relative moving amount with respect to the reference station and a variation of a double phase difference is found based on a positional relation therein, and the relative speed of the moving station is found based on the variation of the double phase difference of a carrier phase and the speed convertion coefficient.
