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. Features .

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.
