That's the archive.org mirror of the openly declared edited from raw logs version released by Malaysia .. so not "my source" which, back in the day, were the raw logs from ground stations.
The specific issue I have with hyper focused attention on these specific logs and hoorah about "weird data" is that I haven't seen much in the way of properly comparative analysis of a super set of broad fleet Inmarsat logs ... these in general are the trailing edge of quality data, riddled with nuls, semi handshakes, line noise, etc.
Transponders are for positioning, black boxes for logging important flight data, diagnostic interfaces for mechanics in hangers ... and component level Inmarsat .. pretty much not more than a curiousity of "because we can" that's occasionally useful when a properly formed messages truly indicates an inflight issue.
Ping routing and ping times were never meant to be consistent nor used for gross "half-LORAN" positioning .. this is all happenstance after event signal engineering hack work.
