2 Europe navigation satellites in the wrong orbits

PARIS (AP) — European space officials say they're investigating whether the inaccurate deployment of two satellites will complicate their efforts to develop a new Galileo satellite navigation system that would rival America's GPS network.

The European Space Agency and launch company Arianespace say the satellites ended up in off-target orbits after being launched Friday from Kourou, French Guiana, aboard a Soyuz rocket.

Saturday's agency statement did not explain whether their orbital paths could be corrected. Arianespace said the satellites settled into a lower, elliptical orbit instead of the circular one intended, and initial analyses suggested the mishap occurred during the flight phase and involved the Fregat upper stage of Soyuz.

"Our aim is of course to fully understand this anomaly," Stephane Israel, Arianespace chairman and CEO, said in a statement. "While it is too early to determine the exact causes, we would like to offer our sincere excuses to ESA and the European Commission for this orbital injection that did not meet expectations."

Israel said Arianespace along with customer ESA and the Commission will create an independent panel to investigate what caused the inaccurate deployment and to develop corrective actions so Soyuz launches can resume.

The European Union hopes to have its 30-satellite Galileo navigation network operating fully by 2020. The Prague-based program oversaw the launch of its first two satellites in 2011, two more in 2012, and two more Friday.

Jean-Yves Le Gall, president of the French space agency CNES, said the investigation still needed to determine precisely how far off course the satellites were. He said European Space Agency experts in Toulouse, France, and Darmstadt, Germany, were calculating whether small motors inside the satellites would be strong enough to push them into the correct orbit.
