alt Hacker NewsI see ships crossing land. Does that mean that they turned off their transponder or whatever after leaving port and turned it on upon arriving at the destination port? I suppose the software just shows the straight line path at the calculated average speed. Look at the Eastern US for May 3-4.
There needs to be an AIS receiver to pick up the ship's transponder, which is why most of the free ship tracking sites only work near the coast.
This seems unusual if you're used to ADSB tracking sites, since the line of sight goes much further due to elevation. There's also more receivers feeding them.
