TELECOMMUNICATION DEVICE, POSITIONAL INFORMATION ACQUIRING SYSTEM, AND POSITION INFORMATION ACQUIRING METHOD

摘要

PROBLEM TO BE SOLVED: To solve a problem that the all terrestrial positional information cannot be detected about a device set up in the interior parts building, since positional information from the satellite cannot be received in interior parts of a building.

SOLUTION: The positional information acquiring system is provided with at least two position receiving devices 12, 13 outside a building 100, for receiving positional information through antennas 10, 14 and broadcasting the received positional information inside the building 100. At least one telecommunication device 21 is set up in the place where positional information from at least two position receiving devices 12, 13 can be received internally in building 100. The telecommunication device 21 receives at least two positional information and detects the distance between the position receiving devices and itself relating to the broadcasting origin of the positional information. The telecommunication device 21 detects the positional information by using the detected distance and registers it.
