Garage TinyTracker

TinyTracker is a device that can be used to relay AIS messages from a ship, including its own position, speed, etc. to land using its regular (satellite) internet connection, giving land based personnel the same view available on the on-board ECDIS.



  • Same data about own ships that can be purchased from Marinetraffic, but cheaper
  • “ECDIS”-like on shore view of ships nearby own ships

  • Installation requires read-only access to NMEA bus on the bridge, and network connectivity with two ports on a specific IP open.
  • Main risk: The device does not deliver any data to land, for whatever reason.
  • The longer we can test, and on the more diverse ship routes, the better.


Data validation
The data collected from TinyTracker will be validated for consistency by our onshore pipeline:
  • Does any self-reported points and points reported by nearby vessels disagree about location at a certain time?
  • Does two consecutive points imply an unrealistic speed by their times and positions?
    • When taking only self-reported points into account?
    • When taking only points reported by nearby vessels into account?
    • When taking all points into account?
  • Is the distance between two vessels that can see each other greater than realistic reception ranges?

About test driving

  • All test driving is done on your own risk. There are no warranties, not even for fitness for purpose.
  • We can not make any guarantees what so ever that the prototype will even actually work... After all, it is a prototype, not a product
  • That said, we will do everything we can to make sure the prototypes do not affect your other systems negatively in any way
  • Our normal support contracts and response guarantees do not cover prototypes under test driving.
  • However our developers will be very interested in solving & figuring any problems with the prototype and will communicate directly with your staff.
