LOCATION-AWARE SYSTEM, DEVICE AND METHOD

PROBLEM TO BE SOLVED: To provide a location-aware system that is formed of a location-aware device mounted on each mobile, suppresses transmitting traffic, and can accurately grasp mutual locations between the mobiles, to provide its device, and to provide a location-aware method. SOLUTION: The location-aware device 10 compares a self location obtained by the location using a self locating device 11 with the self location obtained from the results of a prediction calculation by a prediction calculation device 14 with a decision processing section 15, and, when the error between the both exceeds a tolerance, reports the self location obtained by the location by transmitting it to the other mobile. While, the location of the other mobile is grasped by displaying it on a display section 13 when the locational information is received from the other mobile, or by displaying the location of the other mobile predicted and calculated based on the received location and velocity vector of the other mobile when the locational information is not received, thereby suppressing the transmitting traffic and accurately grasping respective locations of the mobiles.
