Abstract:
A portable GPS velocity/distance meter comprising: a GPS signal receiving section for receiving a GPS signal from a GPS satellite and outputting positional data including movement velocity data of a carrier of the GPS signal receiving section; a microcomputer having a memory section for controlling the GPS signal receiving section and conducting calculations based on the positional data output by the GPS receiving section in accordance with a stored program; an input section connected to the microcomputer for setting measurement conditions including a predetermined time interval between consecutive GPS signal receiving operations of the GPS signal receiving section; and a display for displaying at least one of a movement velocity and a movement distance of the carrier of the GPS signal receiving section under control of the microcomputer; wherein the microcomputer includes control means for controlling the GPS signal receiving section to intermittently receive the GPS signal and output the positional data at the predetermined time intervals and velocity averaging means for obtaining an average movement velocity of the carrier by averaging consecutive movement velocity data values.
