4 –Azimuth Calibration (
AZ
)
This feature will only be available on Legacy mounts. All new generation platforms (i.e.
Ka-75V, 98H/98G/98V, 1201 etc...) will have this option disabled by default.
Performs a complete Azimuth Calibration.
Antenna will move CW to a set point.
Antenna will move back in the opposite direction to locate Stow switch.
Antenna will attempt to locate the cut-off edges of the Azimuth Stow Switch and center itself.
After detecting at which angles the ST Switch turns OFF, the Azimuth zero position is
calculated and the AZ Zero(Pot) is set at the zeroed A/D value.
5 – Polarization Calibration (
PL
)
Performs a complete polarization calibration. On platforms with tilt sensors the
system will complete a PL Zero point calibration and set the Zero point value. Tilt
sensor must be levelled prior to running the Calibrate PL routine on system with
Polarization tilt sensors.
Antenna will completely rotate counter-clockwise to the physical limit and temporarily record
the A/D value from the Potentiometer.
Antenna will completely rotate clockwise to the physical limit and temporarily record the A/D
value from the Potentiometer.
Based on the A/D values of the two (2) physical limits and the maximum range of motion for
the Mobile Platform, the center angle is determined.
Antenna will center itself and attempt to locate the cut-off edges of the Polarization Stow
Switch.
After detecting at which angles the ST Switch turns OFF, the Polarization zero position is
calculated and the PL Zero is set at the zeroed A/D value.
6 – Manual Compass Calibration (
CM
)
Ensure platform is oriented to point North (see Fig 30. below) this compass
calibration is performed manually. It is intended to calibrate the compass by
moving to three angle positions (0, 90, and 180). The compass is manually
calibrated at each angle and then followed by a compass check to validate the
angle readings. Manual Calibration procedure may require to be performed
multiple times before angle readings are acceptable.
7 – Automatic Compass Calibration (
CA
)
Ensure that there are no metallic objects that could interfere with the Compass,
and that the Mobile Platform is on level surroundings.
Orient the Mobile Platform as depicted in the following figure. If Platform is
vehicle mounted ensure front end (windshield window) is pointed north. It is
