COMMUNICATION ENVIRONMENT PREDICTION TERMINAL, COMMUNICATION ENVIRONMENT PREDICTION METHOD AND COMMUNICATION ENVIRONMENT PREDICTION PROGRAM

摘要

A signal receiving means of a communication environment prediction terminal receives a GPS signal via satellite communication from a GPS satellite. A position information detecting means detects position information indicating a position of a vehicle on which the terminal is mounted based on the GPS signal received by the receiving means. Then, a positioning information generating means generates positioning information including the position information detected by the detecting means, that is, the positioning information indicating a travel position of the vehicle positioned by the GPS signal. A communication information generating means generates communication information indicating a communication environment in an area to which the vehicle has moved, based on the positioning information by making use of the characteristics that the GPS signal is difficult to receive in a point with an obstacle or the like.
