Malaysia is to release satellite data used to narrow down the search for the missing airliner to the southern Indian Ocean.
The country’s Civil Aviation Department and British firm Inmarsat said they would do it “in line with our commitment to greater transparency”.
Some family members of the 239 people on the Malaysia Airlines Boeing 777 have demanded raw satellite data to be made public for independent analysis.
The government says calculations using Inmarsat data showed Flight 370 ended in the Indian Ocean after it went missing on March 8 while flying from Kuala Lumpur to Beijing.
No wreckage has been found and an underwater hunt continues.
Authorities believe the plane was flown deliberately off course, but are still investigating the cause of the disappearance.
