5.2 Calibration
Before the FV-110 can be used you must select a heading input setting in order to make
an azimuth and cable calibration. The azimuth calibration is required in order for the FV-
110 to determine the offset of the ADU zero direction to the bow-to-stern line of the ship.
This procedure is fully automatic. The satellite data for calibration can be entered directly
on the calibration page or you can define a Service profile to be used for the azimuth
calibration. A cable calibration is required in order to record the cable characteristics of
the antenna cable which is used in the FV-110 fixed gain feature. See
Fixed TX gain
principle on page 5-15 for more information.
After the calibration you create the satellite and VSAT modem profiles you want to use
during normal operation, and you can set up blocking zones for the specific installation.
The following sections describe the steps for a successful calibration:
• Heading mode and position mode
• Azimuth calibration
• To set up a service profile for calibration
• Cable calibration
• Operation in gyro-free mode
• Flow chart for calibration (user controlled)
• To make a line up procedure
• Fixed TX gain principle
5.2.1 Heading mode and position mode
You must set the heading mode and the position mode before you start the calibration
procedure.
1. Go to the page SETTINGS > Navigation .
2. Select the desired heading input.
Important
You must logon as an administrator to do a calibration.
See
Administration on page 5-40.
Note
If you change the heading settings from external to fixed or vice versa you must
make a new azimuth calibration.
