PROBLEM TO BE SOLVED: To provide a GNSS (Global Navigation Satellite System) receiver that can remove the error of the speed measuring value by oscillation of an antenna without delay, and does not need special setting work.;SOLUTION: The GPS receiver 2 includes a GPS antenna 4, a GNSS position/speed calculator 11, a magnetic azimuth sensor 5, a tilt sensor 6, and an oscillation speed removal unit 15. The GPS antenna 4 is attached to a ship, and receives a signal for positioning from a GPS satellite. The GPS position/speed calculator 11 calculates the GPS speed based on the signal for positioning. The magnetic azimuth sensor 5 detects the absolute azimuth of the bow direction of the ship. The tilt sensor 6 detects the tilt angle of the GPS antenna 4. The oscillation speed removal unit 15, based on the absolute azimuth and tilt angle, calculates the error by the oscillation of the GPS antenna 4 and removes it from the GPS speed.;COPYRIGHT: (C)2012,JPO&INPIT
