As you have only just joined the thread let me bring you up to speed as I understand it.
yes they are pings
MAS did not subscribe to acars on satcom
MAS adverts say 1st class has sat phones
PAx, engineers etc say this aircraft does not have sat phones
It does not use the newer satcom aerials which were subject to AD for corrosion but has the older two aerials.
"established" opinion and understanding over the read says that it was obviously on and pings include the unique airframe code as that is embedded into all data transmitting devices (If that is not the case there will be loads of aircraft in a similar config where satcom keeps pinging with unidentified sources.)
Not being rude can you tell us what your filed is to make your statement so emphatically, if it is sat comms pls read my post #5173 page 259
