Airplane tracking systems like FlightRadar24 rely on people running radios that receive the ADS-B signal and forward the data on to them. That doesn’t work so well in the middle of the ocean, though: in spots like the mid-Atlantic, there are no islands to speak of.
So, the service is now experimenting with a new approach: putting an ADS-B radio onto an autonomous boat. The boat is a Wave Glider from Liquid Robotics, an autonomous boat that harvests the power of the waves to run propulsion, guidance, and its payload. In this case, that payload includes an ADS-B receiver and a satellite transmitter that uploads the plane data to the service, where it is added to their mix of data sources. The boat is planned to spend the next six to eight weeks cruising about 200 miles off the coast of Norway, listening to the broadcasts of planes flying overhead and relaying them back to HQ. They will then be plotted on the live map in blue.
If you’re interested in building your own plane-trackers, we’ve got you covered, at least on land.
