摘要	PURPOSE:To achieve accurate position detection at a moving body side by receiving information on the absolute address position of the moving body, detected on the ground, by the moving body, and then by correcting it corresponding to continuous detection information on the position of the moving body at the moving body side. CONSTITUTION:The absolute address of a moving body is detected by a ground- side device 50 through an inductive ratio line 10 for absolute address detection, and then transmitted by a data transmission controller 53 and a data signal transmitter 54 through inductive radio line 30 for absolute address position information transmission. Then, it is received by a position information receiver 31 at the moving body side and the pitch of a continuous position detector 21 is corrected by a correcting circuit 41 according to continuous detection information at the moving body side through an inductive radio line 20 for continuous position detection which corresponds to every absolute address. Consequently, an error due to the delay of the reception of the absolute address signal detected on the ground side is corrected, so that accurate position detection at the moving body side is achieved.
