Terminal device, terminal device control method, and terminal device control program

摘要

A terminal device including: receiving condition information generating means for generating receiving condition information indicating a receiving condition of the satellite signals obtained when the speed vector information was generated; speed vector reliability information generating means for generating speed vector reliability information indicating reliability of the speed vector information, based on the receiving condition information; corrected speed vector information generating means for correcting the speed vector information and generating corrected speed vector information, based on the speed vector reliability information; estimated position information generating means for generating the estimated position information indicating an estimated position of the terminal device, based on the average speed vector information and the current position information output in the previous position calculating processing; current position information generating means for generating the current position information by performing the weighted average processing on the estimated position information and the positioning position information etc.
