Technology on antenna acquisition for laser communication system between two ground stations

The composition and algorithm theory of acquisition system were elaborated in detail. The acquisition experimental was completed between two pots of 12.5km distances, By using Information of position offered by Two-antenna GPS system and the algorithm of Coordinates transformation matrix, the azimuth and elevation were obtained which can driver two-dimensional turnplate to complete acquisition. The size of area of uncertainty on laser communication between two pots was 25mard, which was elaborated by using Electronic altazimuth.
