X903-X Synchro Retransmission Unit

NMEA to Synchro Converter

The X903-X is a synchro retransmission unit, converting NMEA 0183 heading data into a legacy synchro signal. As standard the synchro output voltage is 55V Reference and 45V Phase, ideal for retrofitting for older Anschutz systems. Using the optional step up transformer allows for a higher voltage synchro output.

With new gyro systems offering only NMEA 0183 data output the X903-X is a cost effective solution for older repeater systems, autopilots, and navigation equipment that require a synchro gyro signal.

Various synchro ratio are available – 1:1, 9:1, 10:1, 30:1, 36:1, 90:1, 180:1 and 360:1 – and can be selected at the time of installation


  • NMEA 0183 input
  • Various Synchro Ratios Selectable
  • Synchro Output – 55V/115V Ref – 45V Phase @0.2A per phase
  • Step Up Transformer Available for High Voltage Synchro Retransmission

Also available – X903-P Synchro Retransmission Unit
