The shift towards a multi-constellation GNSS environment

Carlo des Dorides. The shift towards a multi-constellation GNSS environmentWith the launch of Galileo Initial Services and the availability of numerous Galileo-enabled chipsets and receivers, users are benefiting from the stronger GNSS performance that a multi-constellation environment provides.

As the GSA’s GNSS Market Report shows, the global GNSS market remains dynamic. GNSS is used around the globe, with 3.6 billion GNSS devices in use in 2014. By 2019, this is forecasted to increase to over 7 billion – an average of one device per person on the planet. Smartphones continue to dominate, being the most popular platform to access location-based services, followed by devices used for road applications. Other devices may be less numerous, but billions of passengers, professionals, consumers and citizens worldwide benefit from their application in efficient and safe transport networks, in productive and sustainable agriculture, and in surveying and critical infrastructures.

Development, Supply and Testing of Galileo Open Service

Development, Supply and Testing of Galileo Open ServiceBefore full service of Galileo Open Service (OS) can be achieved, a new generation of OS-Navigation Message Authentication-enabled user terminals must be developed, tested and implemented, says the European GNSS Agency (GSA).

Because of this, the GSA has launched a new funding opportunity to support the development, supply and testing of a Galileo Open Service authentication user terminal. The Galileo OS will soon provide a Navigation Message Authentication (NMA) feature, known as OS-NMA. Via this feature, users can verify that a navigation message comes from a Galileo satellite and not a potentially malicious source. The Open Service is the Galileo program’s free service for positioning, navigation and timing. Read more…

New Authentication Method to Make Sending False Galileo Signals More Difficult

Galileo satellite signals will become more difficult to falsifyGNSS systems are based on satellites that send out signals, including their location. The distance to four or more satellites makes it possible to determine someone’s geographical position and time. But this process can go wrong when hackers send out signals of their own that drown out the real ones. As the authentic signals are blocked, the position information for the navigation system is no longer correct. Read more…

Galileo Commercial Service Implementing Decision enters into force

Welcoming the adoption of the Galileo Commercial Service Implementing Decision, the European Commission and the GSA confirm that the first generation of Galileo will provide users with High Accuracy and Authentication services. The Commercial Service will complement the Galileo Open Service by providing an additional navigation signal and added-value services in a different frequency band. Unlike the Open Service, the Commercial Service signal can be encrypted in order to control access to Galileo Commercial Services.

“The Commercial Service is unique in that its services are not provided by any other GNSS programme and thus represents a unique opportunity for Galileo to differentiate itself from other systems and offer users an added value to the standard positioning services already available,” says GSA Executive Director Carlo des Dorides.

Timing service based on Galileo

The timing services supplied by global navigation satellite systems (GNSS) are an increasingly important, but often unrecognised, part of today’s modern infrastructure.

This is because the vital role of space-based timing is only exposed when it fails – something that became abundantly clear in January 2016, when a software upload to US GPS satellites induced a 13-microsecond misalignment.

Although this might seem like a small difference, it had a big impact. Read more…

Gradual deployment of Galileo to benefit citizens and business

By Carlo des Dorides*:
Since December, users around the world are being guided using the positioning, navigation and timing information provided by Galileo’s global satellite constellation. In 2017, the European GNSS Agency (GSA) officially takes over responsibility for Galileo operations and service provision.

Our main job is to ensure a return on investment from Galileo in the form of clear, across-the-board services and applications for end users. The first step was the awarding of the Galileo service operator (GSOp) contract to Spaceopal, a joint venture between the German Aerospace Agency (DLR) and Italy’s Telespazio. With an emphasis on service performance, this €1.5bn contract will shape the future of Galileo. Read more…

Galileo clock anomalies under investigation

Galileo Rubidium Clock (RAFS)

As first reported last November, anomalies have been noted in the atomic clocks serving Europe’s Galileo satellites.

Anomalies have occurred on five out of 18 Galileo satellites in orbit, although all satellites continue to operate well and the provision of Galileo Initial Services has not been affected.

Highly accurate timing is core to satellite navigation. Each Galileo carries four atomic clocks to ensure strong, quadruple redundancy of the timing subsystem: two Rubidium Atomic Frequency Standard (RAFS) clocks and two Passive Hydrogen Maser (PHM) clocks. Read more…

Europe’s New Satellite System Will Improve Your Phone

By Lucas Laursen*:
Galileo, a global navigation satellite system that will reach more places and work more precisely than today’s GPS services, is now available for free public use. When it is complete, expected by 2020, Galileo will have taken two decades and an estimated $10 billion to build. But the system, created by the European Union, will make your phone run better and offer new possibilities for both corporate and government users. Read more…

Galileo Science Office

Galileo_EUGNSSGalileo’s initial services declaration is a boon not just for people worldwide but also the scientific community. A precise yardstick is now freely available to study Earth and everything on it, along with the laws of physics.

The Galileo satnav system began operating on 15 December 2016, offering positioning, navigation and timing services to everyone with a receiver. Service availability is based on a minimum of four satellites being visible in the local sky, set to improve as the number of satellites increases from the current 18 to a planned 24 plus orbital spares.

The path towards the autonomous vehicles passes through the European satellites

The future of the autonomous driving is “made-in-Europe”. The European Agency for the global navigation satellite systems (GSA) has kicked-off ESCAPE, a three-year and 5.4 M€ project to exploit the services offered by Galileo in the field of the automated driving. ESCAPE will coordinate some of the most relevant industrial and research institutions in Europe to create a positioning engine for safety-critical applications on the road, namely- the applications involving highly automated driving.
