Simrad GC80 Expanded Gyro System MK2: Multi-Repeater Specifications & Spares

The Simrad GC80 Expanded Gyro System MK2 (Catalog P/N 000-15568-001) is engineered for large merchant vessels, container carriers, passenger liners, and integrated bridge systems (IBS) requiring numerous heading repeaters, wing bearing dials, and analog Rate-of-Turn outputs. Pairing the proven GC80 Master Compass (P/N 27102169) with the high-output Expanded Control Unit MK2 (P/N 000-15037-001), it guarantees uncompromised heading signal distribution across the vessel.

1. Expanded Control Architecture • Signal Distribution

The defining capability of the Expanded System is its built-in distribution board. Unlike compact systems that require external step amplifiers or buffer boxes, the Expanded Control Unit MK2 includes:

  • 10 Independent Repeater Drive Lines: Each line is individually isolated and fused with a dedicated 1A fuse (F1 through F10). A wiring short on an exposed bridge wing bearing repeater will never pull down the primary gyro bus.
  • Multi-Channel NMEA 0183 / IEC 61162-1/2: High-speed serial sentences ($HEHDT, $THS, $HEROT) supporting update rates up to 50 Hz for radar, ECDIS, and autopilot.
  • Analog Rate-of-Turn Output: Direct voltage output for analog steering gauges and VDR recording.
  • Step by Step Transmission: Compatible with classic 24V DC stepper repeaters.
