UPDATE: Today’s the day. Check back to the Inside GNSS website for updates on today’s launch.
A European Ariane 5 rocket followed dual rail tracks across the Guiana Space Center in South America on Monday on the way to its launch complex Monday, a day before today’s scheduled blastoff with four satellites to expand the Galileo navigation network. Also, you can follow the launch live at Spaceflight.com.

At the lavish European Satellite Navigation Competition Awards Ceremony, we caught up with Carlo des Dorides, general director of the European GNSS Agency (GSA), who updated us on the status of the much-anticipated Galileo Commercial Service (CS).
“On the CS, we are dialoging extensively with EU member states, because there is a more and more consolidated view that there could be an advantage to providing the service for free,” des Dorides said.

Four of the latest set of Galileo navigation satellites will be launched on Ariane 6 rockets as the European Space Agency has announced it will become Arianespace’s first customer for Europe’s new vehicle.
The launches are scheduled between the end of 2020 and mid-2021, using two Ariane 62 rockets – the configuration of Europe’s next-generation launch vehicle that is best suited to haul the two 750-kilogram navigation satellites that operate in a 23,000-kilometer medium-Earth orbit.

Trimble announced that its Trimble VRS Now networks — powered by Trimble Pivot Platform software — can now process Galileo observation data in its network-modeled Virtual Reference Station (VRS) solution. As a true five-constellation technology using GPS, GLONASS, BeiDou, QZSS and now Galileo observations, Trimble VRS Now delivers even better real-time positioning performance for customers using Trimble networks throughout much of Europe, the company stated.

The Federal Communications Commission is being asked to choose between the immediate benefits of officially improving U.S. satellite navigation receivers and the possibility that, in doing so, it may raise interference levels in a neighboring band or make it harder to develop alternative uses for those adjacent frequencies.

Europe’s satellite navigation system, Galileo, is about to go operational on December 15 when the European Commission makes a Declaration of Initial Services at a special event in Brussels. With that, European satellites will provide users with global positioning, navigation and timing information for the first time.

The navigation sensors for location-based services (LBS) are complex technical systems. Modern technical science can answer most questions about the optimality of particular position determination methods, signal processing algorithms, electronic circuits or similar well-defined problems, but the rigorous answer to the questions concerning the optimal LBS positioning sensor are still a big problem.

CorvajaSpeaking at his annual press conference in Paris last Friday (January 17, 2014), European Space Agency (ESA) Director General Jean-Jacques Dordain was cool, collected and, importantly, positive, as he laid out plans and parried questions on a whole range of ESA issues. From the Rosetta mission to manned space flights, Swarm, Gaia, Sentinel and Copernicus, and of course Galileo, he set the stage for an ambitious 2014.
