Pointing procedure
summary
The antenna pointing process consists of four main steps:
•
Entering installation parameters
•
Coarse pointing
•
Fine pointing
•
Pointing validation
This section provides a brief overview of each of these processes.
For details, see Chapter 2 –
Entering
installation parameters
After completing physical installation of the satellite modem
hardware, the installer connects a laptop to the satellite modem
and accesses the LUI using a standard Internet browser. The
installer then enters the satellite modem and antenna installation
parameters. These installation parameters include:
•
Terminal site name (satellite modem ID)
•
Satellite orbital location, or
A Code
•
Antenna size, or
B Code
•
Outdoor unit (ODU) power, or
C Code
•
Satellite ID, or
U Code
•
Latitude and longitude of the antenna site
Once the installer submits these parameters, the satellite modem
enters
Pointing
mode. In this mode, the LUI displays the
calculated azimuth, elevation, tilt angle, and antenna polarization
information required for coarse pointing the antenna.
Coarse pointing
After entering the installation parameters, you can begin the
process of pointing the antenna at the satellite. Using the proper
azimuth, elevation, and tilt coordinates obtained from the LUI,
you will point the antenna in the general direction of the satellite
to obtain initial acquisition of the satellite signal.
When the demodulator locks onto the satellite beacon signal, the
signal quality factor (SQF) of the received signal-to-noise ratio
(SNR) pointing signal appears on the DAPT display in the form
of a numerical value from 2 to 255. This value is then used to
coarsely find the peak signal level.
Note:
Azimuth measurements are calibrated relative to
true
north, not magnetic north.
Note:
Do
not
attempt to point the antenna manually by
pulling on the antenna reflector or the feed support arm. This
can cause permanent damage to the antenna.
