PROBLEM TO BE SOLVED: To provide an economical and efficient position management system by retransmitting the positional information, dynamic state information, etc., of the other mobile stations from a base station to a mobile station to display the positions, dynamic states, etc., of the other mobile stations on a display device of the mobile station side and simultaneously transmitting positional information, dynamic state information, etc., to a plurality of mobile stations. SOLUTION: The positional information, dynamic state information, etc., transmitted from the mobile stations to the base station are retransmitted from the base station to the mobile station to thereby display the positional information, the dynamic state information, etc., of the other mobile stations on the display device installed on the mobile station. In addition, a digital mobile radio system is used as a means for transmitting the position information, etc. The positional information, the dynamic state information, etc., transmitted from the mobile stations are received by base station radio equipment and displayed on the display device connected to the position management system, and the base station radio equipment retransmits the received data to the mobile station. This enables the mobile station to visually confirm the positional information, the dynamic state information, etc., of the other mobile stations. This also realizes efficient activities when a plurality of vehicles, etc., move cooperatively. COPYRIGHT: (C)2004,JPO&NCIPI
