Thanks to the data from a satellite communications provider the satellite Inmarsat, now we have a clear picture of the tragic final destination of the flight 370 of Malaysian Airlines.
Detection of course is approximately plus 100 miles. This location is located at the bottom of the South Indian Ocean. Using a scientific model based on the displacement of the Doppler signals of the MH377 flight (another Malaysian Airlines flight) and other similar aircraft routes, Inmarsat's technicians were able to limit the search area of the missing aircraft to a region of the Indian Ocean west of Perth, Australia.
Ο satellite Inmarsat το κατάφερε από τα “pings” του αεροσκάφους. Ο Inmarsat – 3 F1, λειτουργεί από το 1996. Τα συστήματα του δεν έχουν δυνατότητες εντοπισμού θέσης, αλλά έχουν μια γεωστατική τροχιά στις 64,5 μοίρες ανατολικά του γεωγραφικού μήκους. Βασισμένοι στην σχετικά σταθερή θέση του, οι τεχνικοί κατάφεραν να περιορίσουν τη θέση του αεροπλάνου με μια πρώτη ανάλυση του φαινομένου Doppler από το σήμα από pings της πτήσης και κατά προσέγγιση το ύψος του αεροπλάνου. Η έγκαιρη ανάλυση έδειξε ότι το αεροπλάνο έπρεπε να είναι μέσα σε two possible arcs: one in the north, leading to the land, and one in the south, over the ocean. Following this briefing to Malaysian Airlines employees on March 12, Inmarsat technicians continued to perform data analysis, modeling how the signal might be shifted by the Doppler effect over the northern and southern routes.
To create this model, technicians used data from the signals of other aircraft with similar routes. The company then compared the model and data from MH370 to an "excellent match" of the aircraft's signals with the expected models to the southbound route, according to Chris McLaughlin, senior vice president of foreign affairs at Inmarsat. as reported in the Telegraph.
With base data from the last pings of MH370, US National Transportation Safety Board investigators were able to narrow the search area to 3% of the "southern runway".
"We all think he is in this general position," McLaughlin said. "But we can not give you the exact point of landing, or impact. It's not that kind of system. "
