6.3 Calibration
Before the SAILOR 600 VSAT Ka can be used you must 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
600 VSAT Ka fixed gain feature. See
Fixed TX IF principle on page 6-13 for more
information. After the calibration you can set up blocking zones for the specific installation.
The following sections describe the steps for a successful calibration:
1. Calibration
2. Service profile for calibration
3. Cable calibration
4. Manual One Touch Commissioning (BUC calibration)
6.3.1 Azimuth calibration
Azimuth calibration is done toward a satellite of a known position. After finding the
satellite, the system can calculate the azimuth offset of the ADU installation. The satellite
and transponder properties for the calibration can be selected from a list of service profiles
or supplied manually.
You can make an azimuth calibration in the following ways:
• Azimuth calibration (user controlled)
• Automatic azimuth calibration with an active satellite profile
• Automatic azimuth calibration with an active satellite profile
Azimuth calibration (user controlled)
1. On the page
SERVICE > Calibration
, in the section
Azimuth calibration (user
controlled)
, select
User defined
in the
Satellite
drop down list.
2. Type in the longitude of the satellite.
Important
Make sure that the modem is switched off at this point. Switch on the
modem after the cable calibration.
Important
You must log on as an administrator to do a calibration. See Administration
on page 6-32.
Note
If you do not want to enter the satellite data on the calibration page you can
select a dedicated satellite service profile for calibration and select it. For
information how to set up a service profile see 6.3.2.
Check that the satellite transponder is visible from the location of the installation
and that it is at an elevation angle between 5 and 70 degrees.
