PURPOSE:To contrive the reduction of the required time for acquisition by deciding pseudo acquisition in parallel with a spatial region and a frequency region being two large factors of the pseudo acquisition and applying further correction acquisition control. CONSTITUTION:A spatial region pseudo acquisition decision and correction control section 40 and a frequency region pseudo acquisition and decision control section 50 are rovided so as to allow the pseudo acquisition decision correction control processing to be applied to the spatial region and the frequency region separately, both the sections are interfaced with an antenna system 20 and a reception equipment 30 respectively, thereby forming an interface system sending/receiving pseudo acquisition and decision correction signals 200, 300 and their operating state signals 210, 310. Start signals 400, 500 are outputted simultaneously from a satellite acquisition supervisory control section 60 managing mainly the start and end of the satellite acquisition to pseudo acquisition discrimination control sections 40, 50 of spatial and frequency regions respectively, the functions of each section are processed in parallel and the end of satellite acquisition is attained while the condition of the satellite acquisition is satisfied in receiving both end notice signals 410, 510 from each section.
