6.2 Calibration
Before the SAILOR 900 VSAT High Power 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 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 SAILOR 900 VSAT High Power
fixed gain feature. See
Fixed TX gain principle on page 6-17 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
6.2.1 Heading mode and position mode
You must set the heading mode and the position mode before you start the calibration
procedure.

Important
You must log on as an administrator to do a calibration. See Administration
on page 6-41.
Note
If you change the heading settings from external to fixed
or vice versa you must make a new azimuth calibration.
