Malaysia provides technical details leading to conclusion of MH370's ending

KUALA LUMPUR, March 25 (Xinhua) -- Malaysia's Transport Minister Hishammuddin Hussein said Tuesday that UK Air Accidents Investigation Branch (AAIB) provides further details as how the data is analysed.

He said Inmarsat, a British satellite telecommunications company, developed a second innovative technique in recent days which considers the velocity of the aircraft relative to the satellite. According to his words, the Inmarsat technique analyses the difference between the frequency that the ground station expects to receive and one that is actually measured. This difference is the result of the Doppler effect and is known as the Burst Frequency Offset.

"The Burst Frequency Offset changes depending on the location of the aircraft on an arc of possible positions, its direction of travel, and its speed. In order to establish confidence in its theory, Inmarsat checked its predictions using information obtained from six other B777 aircraft flying on the same day in various directions. There was good agreement,"said Hishammuddin.

Yet he also mentioned that while on the ground at the Kuala Lumpur airport, and during the early stage of the flight, MH370 transmitted several messages. "At this stage the location of the aircraft and the satellite were known, so it was possible to calculate system characteristics for the aircraft, satellite, and ground station," he said.

"This analysis by Inmarsat forms the basis for further study to attempt to determine the final position of the aircraft. Accordingly, the Malaysian investigation has set up an international working group, comprising agencies with expertise in satellite communications and aircraft performance, to take this work forward," said the statement.

Hishammuddin Hussein said as a result of the new data analysis, the search and rescue operation in the northern corridor has been called off, "We have also stopped the search and rescue operation in the northern part of the southern corridor, close to Indonesia. "

He pointed out that all search efforts are now focused in the southern part of the southern corridor, in an area covering some 469,407 square nautical miles, as against the 2.24 million square nautical miles which was announced on March 18.

Hishammuddin further mentioned that no flights from Perth to the search area took place Tuesday, due to the bad weather. "6 Chinese ships are currently in the search area, and are expected to arrive within the vicinity of MH370's last known position by Wednesday morning."

He said that two Korean aircraft left Subang airport for Perth Tuesday morning, to help in the multinational search operation. " HMAS Success is also currently in the search area," he added.

"The American Towed Pinger Locater an instrument that can help find a black box - is currently en route to Perth and will arrive Wednesday. The system will be fitted onto the Australian ship Ocean Shield, which is due to dock in Perth on March 28. The Ocean Shield, fitted with the Towed Pinger Locater, is due to arrive in the search area on April 5," said the statement.

When asked about the investigation on the pilot's flight simulator, Malaysian Police Chief Khalid Abu Bakar said the work was still going on, and the police was also waiting for the foreign experts' report.

Hishammuddin said the Malaysian high-level delegation would leave for Beijing Tuesday night. Ahmad Jauhari Yahya, chief executive officer of Malaysia Airlines, said the delegation would give more details to the families about the announcement of Malaysian Prime Minister yesterday.
