There seems to be a problem with some of the data released by the satellite company Inmarsat.
Specifically, the handshake at 00:10:58 on 7/03/2014.
In the left column the difference in time-stamp between the ground station initiating the request and the receipt of the return signal from the aircraft is given as 1.928 seconds. However, the prior handshakes at 19:41, 20:41, 21:41, and 22:41 took 1.996, 1.997, 1.998, and 1.999 seconds.
This would imply that the round trip distance between the ground station and the aircraft changed by about 13,000 miles in 1.5 hours. What gives?
