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.
Enter "Setup Mode" 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.

Antenna Mode
Sets the motor to idle mode to check the antenna's balance.
• Set Idle Mode: Enter "Setup Mode" to modify settings. Releases the elevation
and cross-level motor.
• Reboot: reboots the system.
