The data, which was drawn up by the British company Inmarsat, was released 80 days after the Boeing vanished with 239 people on board.
It consists of a 47-page table of satellite logs from 4pm on 7 March when the plane took off from Kuala Lumpur until its last known contact of this type early the next day. Malaysia's civil aviation authority said the raw data was being released for "public consumption".
The data was used by Inmarsat to calculate that the Beijing-bound plane changed course and was likely to have gone down in the southern Indian Ocean. No trace of the plane has yet been found despite an extensive search in the area led by Australia, first on the surface by air and boat, and then underwater using specialist submarines.
Explanatory notes to the newly released data point out that the ping signals were used to estimate the distance between the satellite and the aircraft, but that they do not pinpoint its exact location."
