Looks to be that Elon's jet is headed to Europe
You may notice that tracking is more sporadic. This is because ADS-B is ground-based, over the water we rely on ADS-C and ACARS, which is satellite-based. An example below is from one of the hobbyists that feed satellite signals to ADSBExchange. The one in the back has been picking up signals for the current flight, this is a California-based ground station. In about 2 hours we will be picking up a signal from the UK one.
@elonjet Hej, I'm running ADSB-B to
#Adsbexchange. Do you have some pointers how to extend to ADSB-C and how to feed?
@Morgennebel @elonjet Contrary to ADS-B which is broadcast by the airplane, ADS-C is transmitted only on request (about every 10mn or so) and goes over inmarsat, I believe it would be rather complicated to listen in...
