PROBLEM TO BE SOLVED: To realize a simplification of a memory of a navigation device while eliminating the need for purchasing the latest map information periodically by a user of a navigator. SOLUTION: A terminal 3 provided on a vehicle 1 receives a radio wave from a GPS(global positioning system) satellite 12 to accurately compute the position thereof. The information of the current position is inputted into a computer apparatus 9 together with information on the destination through an antenna 4 for orbit communication, a communication satellite 5, a ground base station 6 and a ground circuit 7 to compute a course based on the latest map information or the like inputted in a data base 8. The results of computation are inputted into the terminal 3 again through the ground circuit 7, the orbit communication 6 base station and the like to be notified to an operator by a liquid crystal monitor or a voice generation recognizing device 2. |
