How the Parallel Use of GPS and Galileo Benefits Railway Applications

This article focuses on the research project Galileo Online: GO! – which with support from the Federal Ministry for Economic Affairs and Energy (grant number 50NA1510) designs and develops a reliable and high-precision receiver for multi-constellation and dual-frequency GNSS whose suitability and capabilities are tested in railway applications. Project results showcase the advantages of GPS and Galileo if used simultaneously in railway applications.

What is navigation message authentication?

Q: What is navigation message authentication?  

A: As of today, all open civil GNSS signals are transmitted in the clear, conforming to interface specifications that are fully available in the public domain. Receivers will accept any input that conforms to the specifications and treat it as if it came from a GNSS satellite. Combined with the extremely low power levels of GNSS signals this makes it almost trivially simple to spoof a GNSS receiver.

Ariane 5 Mission with 4 Galileo Satellites set for Dec. 12 Liftoff

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.

Fundamental Rethink for Galileo Commercial Service

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.
