The document released on Tuesday comprises 47 pages of data, plus notes, from British firm Inmarsat. Flight MH370 went missing on 8 March as it flew from Kuala Lumpur to Beijing. There were 239 people, mostly Chinese nationals, on board. No trace of the aircraft has been found, nor any reason for its disappearance.
The satellite data released includes the hourly "handshakes" between the plane and a communications satellite that led investigators to conclude that the plane ended its journey far off Australia.
"Inmarsat and the DCA have been working for the release of the data communication logs and the technical description of the analysis," Malaysia's civil aviation authority said in a statement."
