iii. The Antenna will now rotate in 90 intervals and attempt to
calibrate the compass.
iv. A message prompt will appear to notify you that the Compass
Calibration has been completed successfully or not.
Calibrate PL
Performs automated Polarization Calibration process.
i. Antenna will completely rotate counter-clockwise to the physical
limit and temporarily record the A/D value from the Potentiometer.
ii. Antenna will completely rotate clockwise to the physical limit and
temporarily record the A/D value from the Potentiometer.
iii. Based on the A/D values of the two (2) physical limits, and the
maximum range of motion for the Mobile Platform, the PL Pot
Factor is calculated.
iv. Antenna will center itself and attempt to locate the cut-off edges of
the Polarization Stow Switch.
v. After detecting at which angles the ST Switch turns OFF, the
Polarization zero position is calculated and the PL Pot Zero is set
at the zeroed A/D value.
vi. You will then be prompted to enter the Platform ID Number prior to
finishing the Calibration Process.
