An information center apparatus has a communication section, a motion information calculating section, a communication delay time calculating section, a communication cycle waiting time calculating section, an error estimating section and a correcting section. The communication section acquires reported current position information of a first moving body apparatus and reports a corrected current position information to a second moving body apparatus. The error estimating section estimate an error in the reported current position information with respect to an actual current position of the first moving body apparatus based on motion information calculated by the motion information calculating section, communication delay times calculated by the communication delay time calculating section, and a communication cycle waiting time calculated by the communication cycle waiting time calculating section. The correcting section corrects the reported current position information using the error estimated by the error estimating section to obtain the corrected current position information.
