Figure 11- Representative Inclined Geostationary Geodetic Path
As seen in figure 11 the Latitude, and Longitude of the path can easily be described in terms of
sine and cosine. These trigonometric functions then become the basis of the mathematic
tracking model.
The periodic beam pointing optimization (step tracking) moves the antenna to follow the path of
the inclined satellite. Look angle measurements are taken after each completed step track. This
data is used by the IntelliTrack tracking algorithm once enough data points have been collected.
Integrating a step track data table with the IntelliTrack mathematical modeling provides a more
consistent and continuous function during tracking.
4.1.3 IntelliTrack Operation
The IntelliTrack tracking module can be imbedded in the standard AAQ acquisition process. It can also
be manually activated through the AAQ GUI if a full acquisition process is not needed (when the AAQ
has already initialized all sensors and has a SatTant heading). Once the module has been activated the
antenna will perform step tracking at regular intervals
.
The module can be used with any signaling
device configured to be used with the antenna system, but a beacon receiver is suggested for pointing
accuracy.
The IntelliTrack tracking module is integrated for a target satellite profile (via configuration item
settings) and will be activated through the Acquire command on the AAQ GUI. This is
recommended for the first acquisition after power on. When the Acquire command is run, the
