A SATELLITE TRACKING ANTENNA SYSTEM OF CORRECTING TRACKING ERROR DUE TO MOVEMENT OF A VEHECLE AND A METHOD THEREFOR

摘要

The present invention, more specifically, optimum orientation by so as to direct the reflector of the satellite tracking antenna to the target satellite direction receiving the satellite signal, and the tilting in the direction of up, down, left, and right of the satellite tracking antenna with a satellite signal level measurement tracing (tracking) reflection the azimuth direction (right and left) or by the elevation measure the level value of the satellite signal sampled with respect to a specific direction in the direction (up and down), calculating an error signal by using a predetermined formula, and in the error signal based on the generated control command signal in accordance it relates to a satellite tracking antenna system and satellite tracking method of controlling so as to coincide with the center axis of the satellite signal main lobe aiming axis of the reflector.; The satellite tracking antenna system, a target and directed to the satellite direction of the reflection plate for receiving a desired satellite signal in accordance with the present invention; The first azimuth position and the calculating a first azimuth position and a n-th cycle of the second first azimuth measuring a difference between the azimuth satellite signal level values ​​sampled with respect to the azimuth position of the n-th cycle of the trace period of the reflector, and trace period of the n-1 first cycle and the second, and calculating a second azimuth measurement value of a difference between the azimuth satellite signal level values ​​sampled with respect to the azimuth position, the azimuth angle using the first azimuth measurement value and the second azimuth measurement value of the azimuth signal level measuring unit for generating an error signal; Azimuth position / speed control unit for using the azimuth error signal to generate an azimuth control command signal with respect to the azimuthal direction of the reflection plate; And is characterized in that according to the azimuth control command comprises a reflector driving means for driving the reflector in azimuth direction.
