Overview
The INTRAC™ 204 Antenna Control Unit
enables satellite earth station antennas to
accurately track geosynchronous satellites with
orbital inclinations up to and beyond 10°. The
unit offers superior tracking integrity with any C-
Band antenna up to 9.6 meters and any Ku-
Band antenna up to 4.5 meters. The control unit
uses the INTRAC (

ontrol) algorithm which has been developed
and refined over a 20 year period. It offers
exceptional
immunity
to
propagation
disturbances and fades, maintaining reliable
pointing accuracy even at low angles of
elevation in regions of high scintillation.
The INTRAC 205 is compatible with INTELSAT
and EUTELSAT SCPC tracking specifications.
It is able to tolerate signal fluctuations that
defeat step track and memory track controllers
and is resilient to loss of tracking signal, the unit
will maintain tracking integrity for blackout
periods up to 72 hours. The non-volatile
memory ensures that accurate tracking is
resumed after power failure.
The unit incorporates 36VDC motor drive
circuits providing a single box solution that is
simple to install, reducing set up costs. It
features full remote monitoring and control via
an RS232 / RS423 serial interface. Average
tracking signal degradation is less than 0.2dB.
The INTRAC 204 features a two-line LCD
display and can be supplied with an integral L-
Band beacon receiver.
