| <b>Novel</b> analysis helped narrow <b>Malaysian</b> jet search | CTV News Posted: 25 Mar 2014 05:32 AM PDT The Associated Press Investigators are closer to solving an international aviation mystery thanks to a British communications satellite and classroom physics. A masterful analysis of a handful of faint signals sent from Malaysia Airlines Flight 370 to an Inmarsat satellite led officials to conclude that the Boeing 777 crashed in a remote part of the southern Indian Ocean. More precise information about the plane's position when it sent the last signals is helping authorities refine the search being undertaken by planes and ships in seas 2,500 kilometers southwest of Perth, Australia. Investigators had precious little information to examine otherwise because the transponder, identifying the jet to air traffic controllers, was deactivated about the same time the jet veered off course from its original destination, Beijing, early March 8. THE PINGSEven with other communications shut down, the plane sent an automatic signal - a "ping" or a "handshake" - every hour to an Inmarsat satellite. The pings did not show the jet's location, speed or heading, but an initial analysis showed the last ping came from a position along one of two vast arcs north and south from the Malaysian Peninsula. For its more detailed analysis, Inmarsat studied the pings sent from Flight 370 on the ground at Kuala Lumpur airport and early in its flight. It considered aircraft performance, satellite location and other known factors to calculate the possible positions, direction of travel and speed of the plane. It then compared its predictions to six other Boeing 777 aircraft that flew the same day, and found good agreement, according to Malaysian Defense Minister Hishammuddin Hussein. Inmarsat did not respond to repeated requests for comment from The Associated Press. DOPPLER EFFECTThink of a horn being honked in a passing car. To an observer, the sound is high pitched as the car approaches and is lower after the car passes. That's because on approach, each successive sound wave is sent from a slightly closer position to the observer. The sound waves get compressed, resulting in a higher frequency. The opposite happens as the car moves away. It's called the Doppler effect for Austrian physicist Christian Doppler, who first put forward the theory in 1842. The same effect applies to "pings" from the plane to the satellite orbiting in a fixed position, which would arrive at a higher frequency if the plane was moving toward the satellite and decrease in frequency when moving away. "By analyzing that you can determine speed and direction," said Joseph Bermudez Jr., chief analytics officer and co-founder of AllSource Analysis, a commercial satellite intelligence firm. And by determining the area from which the last signal was sent, then estimating fuel left, it "could give you an approximate area of where the aircraft impacted." MORE ANALYSISInmarsat sent its data to investigators days after the plane went missing. But it continued to run its own analysis to see if it could wring out any more clues. The company's engineers were dealing with a "totally new area," Inmarsat's McLaughlin told the BBC. "This really was a bit of a shot in the dark." However, the latest information could only go so far in pinpointing the jet's location. "We can't help you with any closer data," he said. Satellite specialists were impressed by Inmarsat's analysis. "They exploited a digital trail that was never intended for that use. It was just a shadow that somebody spotted and made use of," said David Cyganski, dean of engineering at Worcester Polytechnic Institute. Gregory D. Durgin, a professor who teaches satellite communications at the Georgia Institute of Technology, said that because Inmarsat was using a different kind of satellite in a novel way, he expects it would locate the last ping from the Malaysia Airlines plane within "around 100 miles of precision."

It became a private company in 1999 and listed its shares in London in 2005.

| <b>Malaysia</b> assessing possible plane wreckage claim (Update) Posted: 29 Apr 2014 09:55 AM PDT Apr 29, 2014In this aerial photo taken April 29, 2014 provided by the Australia Defence Force, multinational air-crew and aircraft involved in operation "Southern Indian Ocean" are assembled for a photo at RAAF Base Pearce, in Perth, Western Australia. Seven nations, including Australia, New Zealand, the U.S., South Korea, Malaysia, China and Japan, have flew daily search mission out to the southern Indian Ocean in the massive multinational hunt for the missing Malaysia Airlines Flight 370. (AP Photo/Australian Defence Force, Cpl. Colin Dadd) The countries searching for the missing Malaysian jet are assessing a claim by a resource survey company that it found possible plane wreckage in the northern Bay of Bengal, Malaysia's defense minister said. The location is far from where the underwater and surface search has been concentrated for weeks. Australia-based GeoResonance Pty Ltd. stressed that it is not certain it found the Malaysia Airlines plane missing since March 8, but it called for its findings to be investigated. The company uses imaging, radiation chemistry and other technologies to search for oil, gas or mineral deposits. In hunting for Flight 370, it used the same technology to look on the ocean floor for chemical elements that would be present in a Boeing 777: aluminum, titanium, jet fuel residue and others. GeoResonance compared multispectral images taken March 5 and 10—before and after the plane's disappearance—and found a specific area where the data varied between those dates, it said in a statement. The location is about 190 kilometers (118 miles) south of Bangladesh. Malaysian Defense Minister Hishammuddin Hussein said Tuesday that China and Australia were aware of the announcement. "Malaysia is working with its international partners to assess the credibility of this information," a statement from his office said.

(AP Photo/Australian Defence Force, Cpl. Nicci Freeman) The Joint Agency Coordination Center, which is heading up the search off Australia's west coast, dismissed the GeoResonance report, given that the arc of ocean search crews have been scouring for weeks is well south of the Bay of Bengal. "The joint international team is satisfied that the final resting place of the missing aircraft is in the southerly portion of the search arc," the center said in a statement. GeoResonance said it began trying to find the plane before the official search area moved to the southern Indian Ocean. "The only motivation is to help the families of the missing passengers and crew, knowing the company has the technology capable of the task," it said. Flight 370 was carrying 239 passengers and crew from Kuala Lumpur to Beijing when it disappeared the morning of March 8. Radar tracking and communications from the cockpit showed the plane reached cruising altitude without incident, but it veered off course for unknown reasons and flew west across the Malay Peninsula. India, Bangladesh and other countries to the north have said they never detected the plane in their airspace. The jet had contact with a satellite from British company Inmarsat for a few more hours, and investigators have concluded from that data that the flight ended in the southern Indian Ocean. An underwater signal consistent with an aircraft's black boxes was detected in that search area off western Australia on April 8, but no conclusive evidence has been found. GeoResonance said it gave its preliminary findings to investigators on March 31 and was surprised by a lack of response. That claim could not be confirmed.
