Abstract
The terminal apparatus has: positioning vector information generating means for generating positioning vector information which indicates a passing direction and a passing speed, based on the satellite signals used when each item of the current position information was generated; passing speed information generating means for generating passing speed information which indicates a passing speed of the terminal, based on the Doppler shift information and the transmitting frequency information; speed vector information generating means for generating speed vector information which indicates a passing direction and a passing speed of the terminal apparatus with respect to each of the communication base stations, based on the transmitting direction information and the passing speed information; combined vector information generating means for generating combined vector information which indicates a passing direction and a passing speed of the terminal apparatus, based on a plurality of the passing vector information; and current position information selecting means.
