A method of controlling a positioner antenna for satellite into orbit.

摘要

The invention relates to a method Marksmanship TRACKING ANTENNA FOR SATELLITE STEP. The antenna is mounted on a POSICIONADOR three axis comprising: - SHAFT ACIMUT (11), - a lift shaft (12) mounted perpendicularly on AXIS AZIMUTH (11), - an axis of SEUDOACIMUT (13) mounted perpendicularly LIFTING THE SHAFT 812) and supporting the antenna. The positions of these shafts (11, 12, 13) are controlled by an aiming unit AND PROCEDURE IS TO BE PERFORMED SIMULTANEOUSLY THE FOLLOWING STAGES WHEN satellite position is such that the lift shaft (12) EXCEEDS A VALUE OF LIFTING DEFAULT : -A- MODIFY AZIMUTH shaft position (11) at a constant speed V {SUB, AZ}; -B- reposition the lift shaft (12) and SEUDOACIMUT SHAFT (14) to follow the satellite using the following equations X '= X -ARCTG TG [(T)] / COS [AZ (T) - AZ * (T)] Y '' = arcsin [COSEL (T) .SENO (AZ (T) -AZ * (T))] where X '' and Y '' SONRESPECTIVAMENTE POSICOINES THE LIFTING SHAFT (12) AND SHAFT SEUDOACIMUT (13), AZ (T) and (T) RESPECTIVELY ARE azimuth and elevation of the satellite coordinates with respect to the antenna, IT IS A MOMENT IN THE INITIAL POSITION SATELÑITE is such that the lift shaft (12) exceeds an elevation value DEFAULT being obtained AZ (T) AND (T) cOORDINATES FROM ephemeris tables, BEING AZ * (T) equal to AZ (TI) + V {SUB, AZ *} ( T-TI).
