ABSTRACT：Unmanned airship need to regularly communicate with the ground base station, in order to enhance the communication from the airship, the application of real-time tracking airship directional antenna is used. The assignment of the project is to research directional antenna tracking technology, to implement rapid solution of the baseline between directional antenna and the unmanned airship, to ensure that tracking antennas can real-time accurately track the unmanned airship, to enhance the distance of communication between ground mobile base stations and the airship.
Key words: global positioning system (GPS), the transformation of coordinates, positioning, orientation
