ABSTRACT:
A GPS receiver displays information concerning a distance to a destination and a direction with respect to the destination and the like. The information is provided according to a preset operating condition on the basis of data which include position data of the destination which is set in advance and position data of the current position which is obtained from radio waves emitted from GPS satellites orbiting the earth. The GPS receiver includes a memory which stores data of operating conditions corresponding to first, second, third and fourth operation modes. The parameters of the operating conditions of the four operation modes are different from each other in at least a part thereof. The receiver further includes a mode selection section for selecting either one of the operation modes suitable for the actual use of the GPS receiver, an operating section for operating the mode selection section, and a display for displaying various information including information relating to navigation on the basis of the data corresponding to the operating condition of the selected operation mode.
