PROBLEM TO BE SOLVED: To make excellent position detection information obtainable in any place, in a positional information detector using artificial satellite. SOLUTION: This detector is provided with a first positional information detecting means for receiving and demodulating a signal from the artificial satellite to provide the position detection information by all the processing in its inside, and a second positional information detecting means for transmitting a data to an external position processing unit via a communication network to calculate positional information therein, after the signal from the artificial satellite is received and demodulated, and for obtaining the position detection information thereby, and the position detection informations from the first and second positional information detectors are output while being properly switched by a positional information selecting means. |
