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 (INtelligent TRacking Antenna Control) 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.
