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 C­Band antenna up to 9.6 meters and any Ku­Band 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 L­Band beacon receiver.

SPECIFICATIONS

Operational modes

Standby Manual (Jog) Search Remote Control
Auto (INTRAC) Go To (Position Designate)

Tracking Accuracy

Typically better than 0.1dB RMS signal degradation after tracking for 24 hours (with tracking signal), for orbit
inclinations up to 10°

Prediction Accuracy

Typically better than 0.1dB RMS signal degradation over 72 hours (after loss of tracking signal), for orbit
inclinations up to 10°

Backup

Model data is stored in EEPROM and the real time clock supported by battery backup against power failure

Configuration Memory

Configuration data is stored in EEPROM

Tracking Signal

May be derived from an external tracking receiver or optionally from the integral IBR-L beacon receiver

External Tracking Signal

Voltage varying directly with received signal strength (in dB).
Sensitivity 0.1V / dB to 1.0V / dB
Offset + / - 10 volts max
Lost Lock input, contact closure when tracking signal is lost.

Display

2 line LCD display giving the areas of information:
Azimuth angle Signal strength Elevation angle
Diagnostics Polarization angle
Mode of operation Operational menus

Drive Outputs

36VDC, up to 8A for direct drive of DC actuator motors

Limit Switches

Limit switch inputs for elevation, azimuth and polarization. Contacts normally closed

Position Transducers

Inputs for standard resolver position transducers

OPTIONS

Internal IBR-L Beacon Receiver
This option accepts an L-Band signal, with an input level of -80 to -45dBm.
The signal voltage and lock lost indicators are generated internally. The need for an external beacon

receiver is eliminated.

Remote Control Terminal

IBM PC compatible software is available to provide a remote control terminal function. The terminal
monitors and controls the INTRAC via the standard serial remote control port and provides facilities for
managing and storing multiple orbit models. Alarm information is still available at the front panel.

Polarisation Option

Option to accept a polarization position transducer and to drive a 36VDC polarization motor.
