The command station 20 is provided with an area setting part 205 setting prescribed area data for each of mobile stations 10 and the area data set based on the command from a control part 206 is transmitted from a radio antenna 201 via a radio equipment 202. The positional data from the mobile stations 10 is received by the radio equipment 202 and is outputted from an output part 209.
