an exclusive look inside inmarsat, the british satellite company solely responsible for pinpointing the search. reporter: this is inmarsat, the company which for 35 years has been used by ships and planes to keep in touch. we were given exclusive access to the network s operation center. here in the satellite control room in london that you see the technology involved, and you start to understand how they came to the conclusions. the satellite involved is inmarsat 3-f1. one of 11 satellites in the inmarsat collection. it s in stationary orbit just over the indian ocean and it was to this satellite that mh-370 sent the signal, the so-called handshakes. leading the team here was mark
arcs. they then factored in the frequency differences. the so-called doppler effect. the team concluded mh370 had to have flown south in the opposite direction. it was a startling conclusion. what did you think when you got the data and you started to model it and you put it in and you suddenly realize where this plane probably went. let s check it again. you want to make sure you come to a conclusion like that that you have done the right work and data is as you understand it to be. was there a moment of disbelief? having messages for six hours after the plane is lost is probably the biggest disbelief in terms of what you have. reporter: immarsat quickly realized analysis of data from mh370 to the satellite produced an extraordinary result and needed to be tested. so they round the model against
frequency offset, the doppler effect. that s convinced them it s gone south. what i don t see in these numbers, carol, we ve been looking at them very closely, is a clear understanding of how that math works. now, the officials at inmarsat sat down with our richard quest and explained to him how they went through the process, but even there when he said to them, specifically how did you get this? they kept saying, it takes people with very, very high levels of mathematical and physics training to understand how we got here. that s why even if they re releasing all the right information here, carol, it s going to be very hard for anyone to look at those numbers and say, ah, i ve rebuilt it, recalculated it and i also get this path down by australia. until enough numbers are released to the right experts for them to re-create this on their own independent of the malaysian government, and inmars inmarsat, i think you ll have people unsatisfied that this is
flight diverted hundreds of miles off course and why the semp was then shifted to the southern indian ocean. today s release comes after two months of angry demands from the families of those aboard. they want their own experts to verify that conclusion, but immediately after the release, critics say the report is incomplete, and missing key information that independent experts would need. chief complaint today s release shows the communication logs but does not explain exactly how the british satellite company estimated the plane s last known location. according to inmarsat s ceo, it s malaysia s government keeping those details secret. we have absolutely no problem putting our model in the public domain, and that is a decision for the leading country to put out there. it s clearly information and materials and workings that we contributed into the inve investigati investigation. the proper decision-making around that lies with the malaysian government. okay. so what exactly is
costello. overnight officials released satellite data from the airliners final hours. it s the very information that wildly diverted the search to one of the most remote areas on earth, the southern indian ocean where not a single piece of wreckage has been found. today s release comes after two months of angry demands and accusations from families of those aboard and no sooner did this data go public before even more criticism that key information was being withheld. we ll talk to the partner of one american passenger in just a moment. first, richard qwest has this exclusive look inside immarsat, the british satellite company solely responsible for pinpointing this search. reporter: this is immarsat. the company which for 35 years has been used by ships and planes to keep in touch. we were given exclusive access to the network s operation center. it s here in the satellite
