Delays Continue to Plague Europe’s Galileo GNSS Program

Paul Verhoef, GNSS Programs Manager, European Commission

At this week’s (March 9–11) Munich Satellite Navigation Summit, Galileo program officials — public and private — acknowledged that it faces delays at both ends of its latest schedule.

At the near end, the lead contractor for the Galileo in-orbit validation (IOV) satellites that it is building with a consortium of companies said the first IOV will not launch in 2010 as per the most recent schedule. Instead, said Mike Healy, director of navigation for EADS Astrium, the satellite will not be ready for launch until probably February 2011.

Sampler Plate from Munich Summit

Tony Russo, U.S. National Office for Space-Based PNT

Ah, another Munich Summit plenary session filled with many already-knowns and former unknowns, the latter mostly conveyed in nuances and bon mots.

More about that in news reportage to come.

But in the event’s venue, a recently restored All-Saints Church under der Residenz, the speakers may have felt a little lingering moral pressure to tell the truth. So, a sampler plate of comments may be in order.

GPS Jamming and Interference Sparks UK Concerns, Technical Solutions

Prof. David Last at DSKTN symposium

The noise floor seems to be rising on the subject of GNSS vulnerability to jamming and interference. Recently, the United Kingdom provided the locus for a trio of initiatives that reflect growing anxieties about the widespread global dependence of critical position, navigation, and timing (PNT) applications and infrastructures on the low-power signals from space.

An Atlas 5 rocket sent NASA’s Solar Dynamics Observatory (SDO) up on February 11 on an $850 million, five-year mission to find out more about the sun’s magnetic field activity and space weather and, hopefully, to improve forecasting enough to make it possible to safeguard GPS and other technologies.
