v100GX – Marine Satellite Communication System

· Step 4. Press the “Restart” icon to restart the antenna.

- Rate Sensor: is used to calibrate the DC voltage output from the three rate sen-

sors (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 ped-

estal. 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.

Before calibrating the rate sensors located in the Sensor box, make sure that the

antenna is placed on a rigid and at platform. During the calibration process, any

motion of the antenna should be avoided as it can affect the antenna’s perfor-

mance. Proceed with the following steps to perform the calibration.

· Step 1. Enter Setup mode

· Step 2. Press the “Idle Mode” button to release the elevation and

cross level motor brakes while the antenna is in Setup mode.

· Step 3. Check whether or not the bubble is located at the center

of the button level. If not, move it to the center by following the

previous instruction of Tilt Sensor Bias adjustment.

· Step 4. Press the “Bias Check” button to calibrate the rate sensor.

A blue circle will be displayed next to the Bias Check button if the

calibration is completed. A red circle will be displayed if calibration

failed. A green circle will be displayed during the calibration

process.

- Conical Range: The relative force of the motors controlling azimuth and eleva-

tion. Set the conical range while the antenna is in tracking mode.

- EL Adjust: The elevation adjustment is to offset the angle difference between the

mechanical elevation angle and actual elevation angle. If this value is not properly

adjusted, the antenna may take longer time for satellite search or tracking.

- Search Parameter:

· Wait time: set the time-out for automatic initiation of a search after

the signal level drops below the pre-dened threshold value.
