Aug. 19 (UPI) -- A deep-sea exploration company said it has new data that reveals the likely location of lost aviation pioneer Amelia Earhart's missing plane and will launch a fourth expedition to find it.

The new research from Nauticos offers the "most precise information yet" about Earhart's and navigator Fred Noonan's final position before their disappearance on July 2, 1937.

After restoration and analysis of an identical radio system used by Earhart and Noonan, Nauticos has determined their approximate location at 8 a.m. on the day they vanished, a press release said. This discovery significantly refines the search area near Howland Island, the intended next stop of Earhart's flight.

"Our latest radio communication analysis is a major leap forward in solving one of the most enduring mysteries in aviation history," said Dave Jourdan, president of Nauticos, in a statement. "We have narrowed the search area dramatically, and this new expedition presents our best chance yet to finally locate Amelia Earhart's plane."

Earhart went missing in 1937 during her attempt to be the first female pilot to circumnavigate the earth. Her plane went missing while she was over the Pacific Ocean, flying from New Guinea to Howland Island. The next day, a flight to Howland Island in a Navy seaplane by intended rescuers was grounded because of a rare snow and sleet storm over the Pacific.
