Common GPS could help better track airline flights

Get lost in the woods and a cell phone in your pocket can help camping buddies find you. Drive into a ditch and GPS in your car lets emergency crews pinpoint the crash site. But when a transcontinental flight is above the middle of the ocean, no one on the ground can see exactly where it is — in the air, or worse, in the water.

The disappearance of Air France Flight 477 and its 228 passengers over the Atlantic Ocean this week has critics of radar-based air traffic control calling on the U.S. and other countries to hasten the move to GPS-based networks that promise to precisely track all planes. Current radars are obsolete more than 200 miles from land.

"The technology's there — we've had this stuff for 15 years and little's happened," said Michael Boyd, a Colorado-based airline analyst. "My BlackBerry can be used to track me, so why can't we do it with planes?"

U.S. officials have discussed setting up such a network since the 1990s and the technology is being tested in parts of the country, including Alaska and off the Gulf Coast. A few carriers, like Southwest, already use GPS to help planes make quicker landings that burn less fuel.

But full implementation, estimated at a cost of $35 billion, has languished amid funding delays and disputes over technical complexities. Although Transportation Secretary Ray LaHood has said the project will be among the Federal Aviation Administration's top priorities in the Obama administration, the existing radar system is likely to remain for at least another decade.

"It's a crude system they're using now," said Robert Poole, an aviation expert with the free market-oriented Reason Foundation. "For 100 dollars, you can run down and buy a GPS system, put it in your car and know exactly where you are. But planes don't have it."

Some European and Asian countries are moving more quickly toward establishing pricey satellite systems. But many other countries lag behind, including Brazil, where the ill-fated Air France took off Sunday.

Current air traffic systems do not allow controllers to see a transoceanic plane on radar until it is within about 200 miles of land. Instead, controllers often estimate a plane's location based on flight plans and departure times. Such imprecision leaves planes vulnerable in emergencies, such as water landings, Boyd said.

"If a plane ditches and there are survivors, you may not be able to get to it fast enough," he said. "And if an airplane was hijacked in the middle of the Atlantic Ocean, we wouldn't know until it pops up somewhere else."

A reported electrical system failure aboard Flight 477 likely would have knocked out any GPS devices even if the flight had been equipped with that technology. But under a satellite system, rescuers would have known the aircraft's precise location when the failure occurred, presumably making the search area much smaller and helping authorities locate the wreckage faster. That timeliness that can also be crucial in determining a cause of a crash.

Radar quality varies from country to country. For example, many U.S. control centers at least enable planes to send more frequent updates about their location, even when beyond radar's reach.

But over oceans, including vast blind spots in the middle of the Atlantic on U.S.-European routes, pilots usually have to resort to calling controllers with estimated positions every hour or so. The call-ins can frustrate pilots, especially in and around South America, where radio and radar coverage can be patchy, said retired airline pilot Vaughn Cordle, who lives in the Washington area.

"There's nothing worse than going through the painful exercise of trying to talk to someone and letting them know where you are," Cordle said. "The South American region can be more dangerous because pilots are sometimes on their own."

A plane failing to check in after more than two or three hours can be an air traffic controller's worst fear, said New York-based controller Pat McDonough.

"It's very disturbing to the controller to lose an aircraft — you feel responsible," he said. "I sympathize with those guys watching the Air France flight."

GPS proponents say satellite-based air traffic systems provide another benefit that could have directly affected Flight 477, which disappeared into a band of towering thunderstorms. Such systems would collect information from around the globe and allow for real-time weather maps to appear on cockpit displays, giving pilots a tool to better determine how to navigate oncoming weather.

"The point is if we have GPS to monitor airplanes, could it save lives?" Boyd said. "The answer is clearly yes."

Intel unveils chip for ultra-thin laptops

SAN FRANCISCO (Reuters) -

Intel Corp on Monday launched a lighter, power-saving microprocessor intended for use in ultra-thin laptops, a move by the top chip maker to shore up its lead in mobile computing.

The new processor, dubbed the Pentium SU2700, comes amid investors' fears that cheaper processors such as the Atom, designed for use in ultra-cheap netbooks, are cannibalizing the market share for higher-margin, more expensive chips.

Acer and Asustek have said they will build laptops with the chip, and Microsoft will ensure its software supports it.

Intel expects that by the fourth quarter of 2009, about a fifth of its consumer shipments will be for the new-generation laptops, slimmer and more energy-efficient.

Intel is upbeat on the ultra-thin market and expects "explosive growth in 2009, very similar to the netbook growth," Intel's director of mobile platforms product marketing Uday Marty said on a conference call.

Asustek, which in 2007 pioneered the successful low-cost, no-frills netbook PC in 2007, is expected to unveil five new laptop models based on the technology this year.

Analysts say Intel's CULV platform may offer a cheaper -- but virtually as powerful -- alternative to the traditional processors it makes for laptops, while enabling laptops to begin to approach the diminutive size of netbooks.

Intel on Monday also released three new Core 2 Duo processors and a new mobile chipset.

Nokia says started deliveries of N97 phone

HELSINKI (Reuters) -

The firm said in a statement the model would go on sale in more than 75 countries this month.

Acer May Be First With Android Netbook

Acer plans to launch a version of its Aspire One netbook with Google's Android mobile operating system in the third quarter of this year, a top executive at the company said Tuesday.

The device carries the same Intel Atom microprocessor as on any Aspire One, and it sports a 10-inch screen. A similar Aspire One is currently available from Acer but it comes with Microsoft Windows XP.

The device could be the first Android netbook available worldwide if Acer can beat some rivals, such as China's Guangzhou Skytone Transmission Technologies, which has said its Android netbook is undergoing final testing.

Android is a smartphone operating system developed by Google that is meant to make communications and Web browsing easy, especially on Google sites such as YouTube and Google Maps. The majority of netbooks today use Microsoft's Windows XP.

"We are seeing that Android is becoming more common," said Jim Wong, president of global product operations at Acer. Acer decided to move more quickly to work with Android because there is a strong development movement behind the software, he added.

The Aspire One netbooks Acer displayed at its news conference on Tuesday at Computex were running a dual-boot system allowing users to switch between Android and Windows XP, but Wong said the device that goes on sale later this year will only have Android and another Linux OS.

He declined to comment on pricing, saying only that it will likely be slightly less expensive than an Aspire One with Windows XP.

But he also said the device will not offer any additional power savings compared to an Aspire One with Windows XP. Companies showing other new Android-based netbooks at Computex have said the battery life will be much better.

Current netbooks with Atom microprocessors and Windows XP have around six or seven hours of battery life, but netbooks with ARM microprocessors and Android at Computex are said to offer eight to 10 hours of battery life before needing a recharge.

The difference is the microprocessor. Acer is the first company to show an Android-based netbook with an Intel Atom microprocessor. Other companies have shown Android netbooks with chips from Qualcomm, Texas Instruments and Freescale Semiconductor that have ARM processing cores. These devices offer better power savings.

Acer worked with a Taiwanese Linux outfit called Insyde Software to port Android over to a netbook with an Atom microprocessor.

Running Android on the Aspire One took a lot of work, said an Acer representative, but they were able to modify the software because it's open source.

Netbooks centre stage at Taipei trade fair

TAIPEI Asia's biggest information technology trade show opened in Taiwan Tuesday, with the spotlight on low-priced notebook computers and advanced broadband Internet mobile technology.

The event was given extra significance this year by the participation of 36 Chinese exhibitors in the Computex Taipei, the first time since its launch 29 years ago.

Their participation has been made possible by the rapid improvement in ties between Taiwan and its former bitter rival China since President Ma Ying-jeou came to power on the island in May last year.

The five-day event will also enable Taiwanese notebook PC companies to grab the spotlight ahead of competitors as they showcase their new "netbook" models -- laptops designed primarily for web browsing and emailing.

With many netbooks weighing less than a kilogram (2.2 pounds) and costing as little as 250 US dollars, the crowded market is heating up as the cheaper products gain traction over higher priced computers in the economic downturn.

Worldwide demand for netbooks is expected to more than double this year to 32 million units from 13 million units last year.

Asustek Computer Inc, known for its popular "Eee PC" family launched in 2007, demonstrated its latest items shortly after the opening of the exhibition.

Equipped with a 10-inch (25 cm) display, Asustek's Eee PC Seashell 1008HA touts a 18 mm profile and weighs only 1.1 kilograms (2.42 pounds), making it easy to carry. Its battery lasts up to six hours.

Asustek's rival Acer Inc, the world's number two PC vendor behind Hewlett-Packard, meanwhile unveiled its first Aspire One netbook featuring the partly Google-developed Android operating system and faster Internet speeds.

Analysts say Taiwanese computer makers are expected to take a 60 percent share of the global netbook market in 2009.
