ACARS and Pings

IMO, this is how the protocol works.

ACARS <-> A/C Terminal <-> INMARSAT Satellite <-> INMARSAT Ground Station

Partial ping

From what I can infer from the comm protocol, the partial ping was initiated by the aircraft. I won't speculate on why. The satellite did not know to initiate the ping.

U2 overflights

U2 has a synthetic aperature radar (SAR) payload which sees through the clouds. I have wondered why this has not been deployed. I don't know if NASA has this capability, but I know DOD has this...

WRT Pressure vessels

Not an expert in this stuff, but I find it strange that the bottles would rip from their mounting structure without some of the mounting structure being attached to the mounting screws. Looks too...

Possible INMARSAT rf processing

I am not knowledgeable about the rf front end for the INMARSAT, but I am knowledgeable about AEHF and a few other communication satellites, and I would hypothesize they are similar. The comms...

IOR Orbital elements

My experience, working with orbit analysts on many satellites, some geostationary, some geosync, some other, these are the most incredible analysts there are. They, by discipline, leave no stone...
