摘要：無人飛艇飛行時需要定時與地面基站通訊，為了提高飛艇的通訊距離，應(yīng)用定向天線實時跟蹤飛艇。本文研究了跟蹤天線定向技術(shù)，實現(xiàn)定向天線與無人飛艇基線間的快速解算，保證跟蹤天線能夠?qū)崟r精確地跟蹤飛艇，以提高地面移動基站與飛艇間的通信距離。

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
