2.3.4.
To allow for a variance in AGC delta as a vessel travels from north to south or vice versa, the antenna system
will automatically calculate the tracking threshold based on one of three pre-determined latitude ranges,
“Lower, Middle, Upper”, and their programmed Threshold Offset Parameter. These three ranges are defined
by two adjustable system parameters known as “LOW LAT LIM” and “HIGH LAT LIM”. The Threshold-Offset
Parameter values associated with these ranges are based on an internal lookup table known as the “LAT-
THRESH OFFSET TABLE”. Although set at the factory this table is fully adjustable, either from the ACP or
through the RS-232 serial interface, based on user preference.
