RMRS and RRR Type Approval Certification

Koden KGC-222 GPS Compass is approved by the Russian Maritime and River Registers of Shipping.

Key features:

  • Built-in electronic compass used as a backup sensor acting as a backup heading output should GPS reception be interrupted, for example when sailing under a bridge
  • Pitch/Roll & heave data output When KGC-222 is used with an echo sounder with a heaving compensation function, you can obtain a stable seabed image without interference from heaves and waves.
  • “Quick Start” Heading data is available in just one minute after powering up.
  • KODEN’s own unique phase measurement technology allows achieving heading accuracy of 1° RMS.
  • Along with the heading data, KGC-222 also transmits the vessel’s speed and positioning data.
  • 3 heading data output ports, can be extended to 5 with junction box connection.
  • Compact size. Koden KGC-222 consists of a display unit, equipped with a processor and receiver, and a GPS antenna.

MTRD-104 universal digital repeater can in conjunction with Koden KGC-222 GPS Compass.

MTRD-104 universal digital repeater is designed to display various data received in NMEA 0183 messages. Built-in LCD display enables users to easily monitor all data.

Data can be displayed in different modes such as graphs, analog (relevant device emulator), or digital values. In a digital mode, up to 4 different data types can be displayed on one screen. Also, the user can choose from 5 virtual screens, which can be individually adjusted.

MTRD-104 universal digital repeater receives and processes following NMEA-sentences (total 27 sentences): $xxAPB, $xxBWC, $xxBWR, $xxDBK, $xxDBS, $xxDBT, $xxDPT, $xxGGA, $xxGLC, $xxGLL, $xxGTD, $xxHDT, $xxHDG, $xxHDM, $xxMDA, $xxMTW, $xxMWV, $xxRMB, $xxRMC, $xxVBW, $xxVDR, $xxVHW, $xxVTG, $xxVWR, $xxVWT, $xxXTE, $xxZDA

If you are looking for a heading device that is approved by the RMRS and RRR and can guarantee precise accuracy and stable operation in all operation modes, we recommend you choose Tokyo Keiki TG-8000/8500 Gyro Compass.
