Azimuth and Elevation Trim
Use the ‘Azimuth and Elevation Trim’ when it is necessary to adjust the heading offset
and cage offset while the antenna is tracking the satellite. (C
ondition for trim: Valid GPS data,
Tracking of correct target satellite (Correct satellite longitude), Correct heading angle)
Azimuth Trim: When the operator selects the ‘Azimuth and Elevation Trim’ function, the
PCU calculates the discrepancy between the calculated azimuth angle and the current
azimuth angle. Then, the PCU changes the heading offset to the new heading offset.
Discrepancy of Azimuth Angle = Calculated Azimuth Angle by PCU – Current Azimuth Angle
New Heading Offset
= Current Heading Offset – Discrepancy of Azimuth Angle
Elevation Trim: When the operator selects the ‘Azimuth and Elevation Trim’ function, the
PCU calculates the discrepancy between the calculated elevation angle and the current
elevation angle. Then, the PCU changes the cage offset to the new cage offset.
Discrepancy of Elevation Angle = Calculated Elevation Angle by PCU – Current Elevation Angle
New Cage Offset
= Current Cage Offset – Discrepancy of Cage Angle
