PROBLEM TO BE SOLVED: To control plural airships via a single control station by sending the airship information including the position information on its own airship measured by the airship to the control station, sending the control information on airships to every airship from the control station for the control of airships and adding a biaxial joint and a drive mechanism to an antenna mounted on every airship. SOLUTION: A GPS(global positioning system) receiver 4 mounted on an airship 3 receives the GPS signals 71 from a GPS satellite 7, and a DGPS (differential global positioning system) receiver 5 receives the DGPS correction signals 81 from a stationary satellite 8. Thus, the signals 71 are corrected and the highly accurate position data 61 on its own airship are compared with a prescribed airship stop position. Then the position difference of the airship 3 is corrected by the driving force developed by a drive controller 12. The data 61 are unified into the telemetry data with the state signals of devices including a radio device which are mounted on the airship 3 and sent to a communication satellite tracking device 9.
