at the zeroed A/D value.
vi. You will then be prompted to enter the Platform ID Number prior to
finishing the Calibration Process.
Calibrate AZ
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
range of motion for the Mobile Platform, the AZ Pot Factor is
calculated.
iv. Antenna will center itself and attempt to locate the cut-off edges of
the Azimuth Stow Switch.
v. After detecting at which angles the ST Switch turns OFF, the
Azimuth zero position is calculated and the AZ 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.
Calibrate EL
The iNetVu™ Mobile Software will move the Mobile Platform through its
entire range on the Elevation Axis in order to calibrate the Elevation
Current Limits. This function is typically never used, and is not
recommended for use unless under the supervision or direction of a C-
COM Technical Support Team Member.
Check CP
Tests the compass’ heading and accuracy by rotating the antenna at
90° intervals and comparing the compass readings with the actual
antenna’s movement.
i. Antenna will center itself; move to the proper Elevation for reading
the compass, then read the compass heading.
ii. Antenna will rotate 90° to each of the following positions and read
the compass at each: 0°, 90°, 180°, -90°, 0°
iii. iNetVu™ Mobile Software will compare the compass heading
values read at each position, and determine if they differ by
approximately 90°.
iv. The Compass Check will display a message regarding the
accuracy of the compass.
Calibrate CP
Automatically calibrates compass
i. Ensure that there are no metallic objects that could interfere with the
Compass, and that the Mobile Platform is on level surroundings.
