Antenna – Advanced Info.
This view provides information on the Tilt Sensor Bias, Conical Range, EL Adjust,
Rate Sensor, Search Parameter and Blockage Zone.
• Tilt Sensor Bias: This maintains the elevation and the cross level axes
in order to keep the pedestal parallel to the horizon. Adjust the two solid-state
tilt sensors to provide absolute cross-level tilt of the antenna and elevation
feedback to eliminate long-term pointing drift (error). Tilt bias must be
adjusted when the antenna control board or sensor box is replaced. If the
bubble on the button level located on the sensor box is not centered, please
follow the following steps to adjust the tilt sensor bias.
Step 1.
Enter Setup mode and press the “Ready” button to bring
the elevation and cross-level to 0º.
Step 2. Select “EL” from the drop down list and press the Up and
Down arrow keys to adjust the bubble until it is located in the centerring
of the button level.
Step 3. Select “CL” from the drop down list and press the Up and
Down arrow keys to adjust the bubble until it is located in the center
ring of the button level.
Step 4.
Press the Restart button to reboot the antenna.
• Rate Sensor: is used to calibrate the DC voltage output from the three rate
sensors (azimuth, elevation, and cross-level). 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.
