Our on-board system


Who’s listening?
NMEA data is transmitted to the following ‚NMEA listeners’:

  • MINI-ITX PC with extremely low power needs acting as chart plotter by running appropriate software
  • VHF-DSC (Thrane & Thrane Sailor A1 plus RT4901)
  • CETREK NET MULTI and NET NAV displays in the cockpit
  • Autopilot CETREK 609 & 715
  • WIFI RS232 Server to set up a local WIFI for transmission of data to hand-held devices like IPAD/IPHONE or similar.
For overview:

System options available but currently not used/Redundancies:
  • We do not multiplex the AIS signal, this could be done to display AIS data on the handheld devices
  • The two compass units on-board are redundant. As a matter of principle, data from the autopilot’s dedicated fluxgate unit could be fed back to the NAV system.
  • The GPS 120 is an old stand-alone version. It still may display data parallel to the other displays and may hold up to 250 waypoints. We continue to upload waypoint sets from the PC for display and autopilot operation. This data comes directly from the PC.
  • Neither the autopilot nor the hand-held units via WIFI are set to feed back data into the system but may be done to do so.
