GC80 & GC85 IMO type approved for use aboard standard and High Speed Craft respectively, Simrad GC80 and GC85 gyrocompasses are available with Compact, Dual or Expanded control units forinstallation as part of a single- or multi-gyro system. These control units offer a range of stepper and NMEA 0183 heading outputs for direct connection to heading repeaters, ECDIS, radar, autopilot and other navigation systems. Easily incorporated into new vessels or retrofits, the GC80 and GC85 suit a variety of applications from navigation for merchant vessels to dynamic positioning for OSVs. These gyrocompasses were designed to meet the requirements of demanding offshore applications, and combine sophisticated technology with low-RPM rotation to eliminate the need for regular annual service or oil changes. In the event that service is required, the fully-sealed sensitive elements are field-swappable to allow for onboard service – minimizing or eliminating vessel downtime. RGC50 Smaller and lighter than IMO-approved equivalents, the Simrad RGC50 brings the reliability and performance benefits of a gyrocompass to smaller non-SOLAS workboats, passenger ferries and commercial fishing vessels. The RGC50’s integrated control unit offers a single 1:1 synchro electrical output; the optional GI51 Gyro Interface module translates this into stepper and NMEA 0183 outputs for direct connection to heading repeaters and other navigation equipment. Pendulum Ferry function Essential aboard double-ended ferries with interchangeable bow and stern, the RGC50 and GI51 offer a switchable 180-degree heading offset that allows either end to be configured as the bow quickly and easily during vessel operation.
