This paper made use of the locate function of GPS to determine the speciifc spot beam region of the mobile satellite application station in the IP-STAR satellite, the GIS map library kept in the CPU of the signal receiver and the spot beam database of the IP-STAR satellite; in addition it made use of the obtained information to which spot beam it had switched by means of the software of the user’s terminal computer to instruct the satellite antenna’s automatic tracking and the IP-STAR modem parameters’ automatic modiifcation, so that it realized the function of the automatic instruction of the IP-STAR modem’s access network. This paper achieved the automatic satellite-tracking and access network’s closed-loop control equipment and technique of the IP-STAR mobile satellite application station which were low-cost, simple to control, easy to operate, stable and high-precision.
