Antenna Specific Operation
9711QOR-86 C & Ku-Band TXRX
16-4
16.7.
Target a C-Band Satellite
In this example the ship is at LAT 28.0N, LON 140.0W and Heading is 000.0 degrees true.
When power is turned ON the antenna will initialize to Reflector
A (C-Band Reflector). During initialization the C-Band reflector
will be driven to relative azimuth 000.0 (antenna will be parallel
to the bow of the ship) and elevation of 45.0 degrees.
C-Band Reflector
In this example, we want to target a C-Band satellite at 180W.
The calculated target position of this satellite will be true
Azimuth of 240.8 degrees and an Elevation of 35.5 degrees.
Ku-Band reflector
First, if we do not already know the system settings that we will
use for the C-Band satellite at 180W, we should contact our
airtime provider. We need to know:
•
Is this C-Band satellite Linear or Circular mode, to set
the C-Band Linear/Circular selectable feed using the
Band Selection setting.
•
What TX polarity we will be using, so we can set TX
POLARITY to the appropriate setting.
•
Which signal we will use for tracking so that we can
enter the correct band selection and the values for the
MHz, KHz, FEC, SKEW and NID settings.
NOTE: It’s a good idea to record this information for all of the
satellites that you may potentially use in the regions where your
ship will be travelling.
1.
Access the ANTENNA menu to assure REFLECT A is
selected.
2.
Access the STATUS Menu – TRACKING window and
toggle the Band selection to Lin P or Circ P as
appropriate.
3.
Access the SATELLITE Menu – Tracking Receiver
settings and enter the MHz, KHz and SKEW values, for
the desired satellite, in their appropriate entry windows.
Note that the antenna pedestal has not changed its stance; the
C-Band reflector is still pointed at 000.0 relative. Also note that
for azimuth purposes the Ku-Band reflector is 180 degrees from
the C-Band reflector, so it is currently at relative 180.0 degrees.
