Abstract

PROBLEM TO BE SOLVED: To provide a navigator in which the supply of a power supply to a part of circuits is cut off according to the judgment of the stop operation/the nonstop operation of a vehicle and to the capture state of a GPS satellite and which can lower the capacity of a current.
SOLUTION: A GPS apparatus 1 by which the latitude, the longitude and the altitude of a user's present position can be positioned is installed. A receiving-circuit power supply part 7 which controls the supply of a power supply to a receiving circuit 3 in the GPS apparatus 1 is installed. When a stop operation is judged by the observation of a wheel-speed pulse waveform to be input from a vehicle-speed-pulse-waveform input part 11 or when the capture state of a receiving GPS satellite in the GPS apparatus 1 is worsened, the supply of the power supply to the receiving circuit 3 is cut off.
