Rate Sensor Bias
NOTE
: The rate values of the azimuth, elevation, and cross-level axes were
calibrated to the optimal condition at the factory prior to shipment. If the
additional rate adjustment is required, make sure that the antenna is placed on
a rigid and flat platform. During the calibration process, the antenna must avoid
any motion as it can affect the antenna's performance.

to modify settings manually.
Calibrates DC voltage output from the three rate sensors used to sense antenna
motion in azimuth, elevation and cross-level axes. These are used to sense
antenna motion that corresponds to the ship's motion (roll, pitch, and yaw) for
stabilizing the pedestal. The DC voltage output from each of the rate sensors
may vary by an amount which is directly proportional to the direction and rate of
motion induced on it.
• Rate Sensor Calibration: click the
Rate Sensor Calibration
button to
calibrate the rate sensor automatically. The indicator left of the help button
shows the rate sensor calibration status. (Black: the calibration is ready to
start. Blue: the calibration is completed. Red: the calibration is failed. Green:
the calibration is in process.)
• Save Sensor Bias: click the
Save Sensor Bias
button to save the calibrated
value of the rate sensor to the system.

LNB Pol Sensor
Calibration
(Skew)
Calibrates the LNB pol angle when the control board, the skew motor or belt is
replaced.
• Sat Skew Offset: Displays the skew offset value.
• Mechanical Offset: Displays the skew offset value.
The indicator right of the value box shows the skew offset status.
- Blue: Mechanical skew offset value is less than ±10 degrees.
- Red: Mechanical skew offset value is greater than ±10 degrees.
• Consolidated Offset: Displays the consolidated offset value.
• Pol Sensor Calibration: Calibrates the skew motor and checks the skew
range.
• Mechanical Skew Offset Reset: To reset the mechanical skew offset value
to 0, click on the
Mechanical Skew Offset Reset
button. The mechanical
skew offset is pre-set with a factory default value (0, 1 or 2) depending on the
assembly condition. You may need to reset the mechanical skew offset when
the satellite skew offset is unknown (consolidated skew offset = satellite skew
mechanical skew offset). Mechanical skew offset is set automatically
by moving the Pol Angle left or right in the search or tracking mode.
NOTE
: Each satellite has its own skew offset. Intellian recommends you to
contact your service provider or satellite operator to get the satellite skew offset
value. To set the satellite offset value, go to

Sets the motor to idle mode to check the antenna's balance.
• Set Idle Mode: Enter

to modify settings. Releases the elevation
and cross-level motor.
• Reboot: Reboots the system.
