How does the satellite link on the aircraft know to switch from the IOR to the POR satellite. Any sat wiz kids can tell me how it works? Is it signal strength from the Aircraft or is it signal strength from the Sat itself and then send a handshake change Frequency instruction? If this handshake change freq. instruction is not decoded wouldn't it keep talking to the IOR sat and not the POR one. If this is the case then the omitted 40 degree rings need to be joined again. Which incidentally is right over the airways and initial suspected area of the original search in the South China Sea. Which incidentally hasn't be totally covered by either Nation or agency. Now it is going to be cut short.
Also the other pings in between 01:07am and 08:11am have not been disclosed to us yet.
Is there someone out there who can tell me how Immersat works?
