Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a system allowing position specification of a vehicle travelling on a determined route. SOLUTION: A system for transmitting a positioning signal has GPS signal generating devices 220, 222 and 224 connected to GPS receiving system 200, 202 and 204 for receiving GPS signals via GPS antennas 230, 232 and 234, and repeaters 210, 212 and 214 for transmitting signals via antennas 220, 222 and 224, respectively. Each GPS signal generating device includes a communication I/F for receiving incoming of the GPS signal, a CPU for controlling an operation inside the GPS signal generating device, a memory, a clock, a GPS signal generating section for generating a false GPS signal based on the GPS signal, and an output I/F for outputting the false GPS signal.
