Installation does not seem to be cheap. If you watch the timelapse [0], it does take a while to do that. Although I know Rolls Royce engines already do send their data to satellite, but I am not sure by which means.

What I am interested, is feasibility this: nowadays you can buy sailor lifejackets with personal EPIRB which pings the satellite with your location. I am sure that is a lot of waste weight, but then, Lufthansa is still serving food with steel utensil, so maybe its not as bad.

Also, randomly searching info about black boxes, I've found they have option for 90 day pinger batteries. Perhaps that could've aided MH370 search.

All the planes that disappeared recently (MH370, Egyptair, or AF447) all already had txt based systems that were sending home txt based maintenance messages. All it would take is to also ping a gps coordonate every minute. Doesn't seem very complicated to me. Probably doesn't even require a hardware upgrade.
