Structure of vehicular active antenna system of mobile and satellite tracking method with the system

摘要

This invention relates to a structure of an active antenna system of a mobile and a satellite navigation method using the system. The present invention provides a structure of an active antenna system of a mobile and a satellite tracking method using the system, in which beams are formed and then directed by using sub-array concept, the tracking accuracy becomes to high by using double beam satellite tracking mode for tracking the satellite, tracking loss is reduced and positions are more accurately tracked during movement using an absolute steering sensing mode.
