PROBLEM TO BE SOLVED: To enable a mobile terminal 30 to perform indoor positioning in addition to outdoor positioning, and what is more, to enable highly accurate indoor positioning.;SOLUTION: A plurality of indoor transmitters 10 is installed indoors. The indoor transmitter 10 transmits an indoor radio signal including information indicative of an indoor installation position and having compatibility with a GPS signal for positioning to be transmitted by a GPS satellite 7. A reference station device 20 is installed at an indoor predetermined position, and the reference station device 20 receives the indoor radio signal, generates correction information for indoor positioning, using the information indicative of the received indoor radio signal and the predetermined position, and transmits the correction information. A mobile terminal 30 receives the GPS signal, the indoor radio signal and the correction signal, and enables outdoor positioning, using the GPS signal and performs the indoor positioning on the basis of respective distances to the plurality of indoor transmitters 10, using the indoor radio signal and the correction signal.;COPYRIGHT: (C)2014,JPO&INPIT
