3.0 Operation
After assembly of the antenna has been completed, it is time for it to be made operational. It will be necessary
to first direct it to the desired satellite in order to begin operating the Earth Station Antenna, adjusting both the
Elevation and Azimuth angles appropriately. The procedures in the following sections provide details on how to
correctly position the antenna on the desired satellite.
NOTE:
Ensure that the proper feed system and all electronics have been properly installed before proceeding.
3.1 Acquiring a Satellite
Steps 1 through 7
below are for initial satellite signal spotting:
Step 1 of 7:
Evaluate and determine the required Elevation and Azimuth angles for the satellite of interest.
IMPORTANT NOTE: Steps 2 through 6 below are intended for use with Pedestal Mounted Antenna systems ONLY
Step 2 of 7:
Loosely attach the Manual Actuator Assembly (207882) to the Elevation strut using appropriate
hardware, as shown in Figure 100b.
NOTE:
The drain hole should be positioned downward for proper water drainage.
Step 3 of 7:
Ensure that the locking strut support setscrew is firmly tightened on the Strut Assembly, as shown
in Figure 100b.
Step 4 of 7:
Remove the two indicated strut support setscrews, and attach base angle to corresponding strut
support using the supplied ½ Inch clamping nuts and previously removed strut support setscrews, as shown in
Figure 100b.
Step 5 of 7:
Securely tighten the remaining mounting hardware to achieve sufficient clamping force.
Step 6 of 7:
Repeat the entire process for the remaining Strut Assembly
IMPORTANT NOTE:
DO NOT loosen the Azimuth drive bearings
Step 7 of 7:
If the antenna is on a Pedestal Mount
, move the antenna to the desired Azimuth angle by
adjusting the manual actuator until the satellite signal is spotted.
If the antenna is on a Tripod Mount
, adjust
the Azimuth strut length through the Fine Adjustment Assembly until the satellite signal is spotted.
There are a number of possible procedures for acquiring a satellite.
Kratos
recommends that a Spectrum
Analyzer of some type be used, regardless of your chosen procedure. The following procedures
provide explanations as to how a Spectrum Analyzer is used.
While viewing any Spectrum Analyzer screen, a pure noise signal will likely be observed, as shown below in
Figure 3-1
. Additionally, some transponder signals may be observed above the noise signal, as shown below
in
Figure 3-2
.
