Приемник спутникового слежения

Satellite tracking receiver under Ku wave band satellite beacon signal frequency conversion after the L wave band clear signal processing, demodulates for the antenna servo's position, the pitch error voltage, causes in the movement Che Zai, aircraft-borne, the ship carries the antenna accurate alignment satellite to realize the satellite communication. As a result of the above characteristic, causes this tracking receiver to be possible in the satellite communication command car, the airplane, the steamboat, the emergency command car and so on various domains track random satellite. This receiver has used the advanced digitized technology, overcomes the present to simulate the receiver to float warm commonly used in a big way, the precision and the reliability were bad, operating temperature scope narrow and so on questions, and had a higher sensitivity, the nimble display control connection and the ultra small volume. In addition, the consummation shield structure, enables its antijamming, the quakeproof mobility similarly to be also splendid.
