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.
These ground stations pickup signals from Inmarsat satellites that then communicate with aircraft.

@elonjet I originally parsed this as:

"These ground stations pickup signals from Inmarsat satellites that then communicate with witchcraft."

... and thought things had escalated quickly in a psychedelic way. Was disappointed to reread it as "aircraft".

@elonjet I lost him just south of Iceland and am trying to pick him up on HFDL from Reykjavik.
@elonjet I was definitely not expecting Elon Musk's latest temper tantrum to result in, among other things, me learning about aviation communications infrastructure, but it's a welcome side benefit.
@elonjet
You are great ๐Ÿ˜
BTW welcome to mastodon!
@elonjet Can't wait until Musk bans satellites in backyards from Twitter!
@elonjet This is surprisingly educational!
@elonjet watch Musk try to stop this somehow with his starlink satellites
@erictgilmour @elonjet He could try, sure. But considering that ADS is mandatory for a rather large majority of airplanes, and interfering with those signals is a crime pretty much everywhere, well, let's just say I'd LOVE to see that happen :P
@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...
@sxpert @elonjet This exact thread starts with a picture of satellite dishes and the term hobbyists feeders. I am only asking how can I do the same...
@Morgennebel @elonjet you'd need to build something like the NSA was using in the 80's (remember ECHELON ?) to decode the inmarsat traffic, which then may be encrypted

Follow the bitly Adress will open a Google file PDF. Much smaller and a nice new project...
ADS-C support added - Flightradar24 Forum

Hi all, I am happy to announce that we have added support for ADS-C data. One of our members Andrew rch38084 has written a detailed guide on how to start and get your setup going (thank you, Andrew). If you are interested in setting up your ADS-C feed, please take a look and if you have any questions you can ask Andrew for

@elonjet @Morgennebel I would suggest taking a look at @thebaldgeek โ€˜s info. He is the expert on this.
@MrLiftaviation @elonjet
I'm not sure I follow your question here...
@thebaldgeek @elonjet is this a photo of your setup?
@MrLiftaviation @elonjet
My bio photo? Yes.
Since my main interest is ADSC and satcom ACARS I have the primary dish at the back for 98w and the second test dish at the front for 54w and 98w testing. Only the primary dish has tracking motors to keep on the geostationary satellite.
The smaller 98w L-Band dish is not in this photo, its on the other side of the house. The 54w L-Band patch antenna is on the roof of the house.
The #Inmarsat #STDC feeds are scattered around.
