EU erhöht GPS-Genauigkeit mit eigenem Satellitensystem

Filed under: Uncategorized — by kinstufues @ 9:20 pm

Die Genauigkeit von GPS-Signalen möchte die Europäische Union (EU) erhöhen.
Sie hat dafür nun drei Satelliten ins All geschossen, die bis auf zwei
Meter genau die Position von GPS-Geräten wie Handys oder Navigationsgeräten
bestimmen sollen. Durch die präzisere Navigation und Ortung erhofft man
sich in Europa neue und verbesserte Geschäftsmodelle, unter anderem könnten
Mautgebühren nun zielgerichteter erfasst werden als bisher. Außerdem
könnten beispielsweise Mobiltelefone via GPS konkrete Informationen zu
nahen Sehenswürdigkeiten liefern, wenn man in fremden Städten auf
Entdeckungstour geht.EU erhöht GPS-Genauigkeit mit eigenem Satellitensystem

GPS-Dienst der EU namens EGN

OS bietet einen Vorgeschmack auf das Galileo
genannte satellitengestützte GPS-System, das nach einem mit dem
EU-Ministerrat ausgehandelten Kompromiss bis zum Jahr 2013 startklar sein
soll. Eigentlich sollte Galileo bereits 2008 an den Start gehen, es hat
jedoch Probleme mit der Finanzierung, der Vermarktung und dem Vertrieb
gegeben. Das voraussichtlich in der Einrichtungsphase rund 3,4 Milliarden
Euro teure Projekt wird nun aus EU-Mitteln finanziert. EGNOS löst
europaweit das System der US-Amerikaner, das bisher weltweit genutzt wurde.
Gegenüber dem EU-Dienst soll es laut dem Magazin "Vnunet"
deutlich ungenauer sein. Signale konnten nur auf rund zehn Meter bestimmt
werden, was jedoch vor allem auf Restriktionen des US-Militärs
zurückzuführen ist.

“Allo, Papou,”

He chatted with his children in French — “Allo, Papou,” a son said; “Je t’aime, Papou,” said a daughter. He put on a red clown nose and wagged an index finger at his audience, stealing the show as he crowded in with the space station’s eight other occupants in zero gravity.

Laliberte also asked one of his children why she wasn’t wearing a clown nose, and she said she had forgotten it.

“We were happy he didn’t get space sick,” Barilla told The Associated Press while cuddling their 2-year-old daughter.

An experienced acrobat, fire-eater and stilt-walker, Laliberte also had put on a clown nose before Wednesday’s launch, and brought several to the station for crew mates to try on. He warned he would tickle them while they sleep.

But he has a serious mission as well. He planned to read a poem dedicated to water conservation in a satellite linkup to be shown in 14 cities next Friday. Former U.S. Vice President Al Gore, pop singer Peter Gabriel and Irish rock group U2 also will participate.

Quebec-born Laliberte, 50, is worth an estimated $2.5 billion.

On his return to Earth, he will accompany two of the station’s current crew members aboard one of three Soyuz crafts now docked at the station.

The former street performer is worth an estimated $2.5 billion and holds a 95 percent stake in Cirque du Soleil, which he founded 25 years ago.

But Laliberte may be among the last space tourists for several years, with NASA planning to retire its shuttle fleet next year and rely on Russia to ferry U.S. astronauts to the station — meaning fewer extra seats on the delivery craft.

Russian space agency chief Anatoly Perminov said Friday that Russia will be unable to send tourists to the station if the United States does not continue its shuttle flights.

Third-time space traveler Williams, 51, and first-timer Surayev, 37, will be in orbit for 169 days.

“We are really proud of him,” said Surayev’s wife, Anna, who watched the docking along with their two daughters. “Glad his dream came true, because it took him 12 years to achieve it.”

Circus tycoon clowns around aboard space station

A Canadian circus billionaire boarded the International Space Station on Friday after a smooth ride up from Earth, and promptly played the entertainer by donning a red clown nose for a camera.

Cirque du Soleil founder Guy Laliberte became the seventh paying space tourist to travel to the station, where he plans to mix clownish fun with a serious message about the growing shortage of clean water on the planet 220 miles (355 kilometers) below.

Laliberte floated onto the orbiting outpost along with American astronaut Jeffrey Williams and Russian cosmonaut Maxim Surayev two days after the three had launched in Soyuz craft from the Kazakh steppe.

Laliberte returns to Earth on Oct. 11, while Williams and Surayev will live on the station for nearly six months.

“I’m adapting pretty good. I love that thing — but I ain’t staying six months,” Laliberte said in a video linkup to Russian Mission Control outside Moscow, where his five children and partner Claudia Barilla watched the Soyuz TMA-16 docking on a big screen.
