I/NAV improvements now available to Galileo Open Service users

As of August, 2023, operational Galileo GNSS satellites, with some exceptions, have been updated and are now transmitting an improved I/NAV message. Users will see an enhancement in the Galileo E1 Open Service (OS) performance in terms of robustness and a significant reduction in time to first fix in challenging environments, with both unassisted and assisted GNSS. Backward compatibility is assured, with no impact on legacy receivers and low complexity implementation within OS receivers.

Galileo satellites broadcast different types of data in four navigation messages: the F/NAV and I/NAV navigation messages, a commercial navigation message (C/NAV) and a governmental navigation message (G/NAV). The latest upgrade comprises new features added to the I/NAV message, carried by the E1-B signal. Read more…

EUSPA takes on the EU Space Surveillance and Tracking (SST) Frontdesk

The abundance of satellites is not only responsible for “an unprecedented space traffic jam” but it’s also the cause of a large amount of space debris which is increasing at an alarming rate.

According to the European Commission, over 1 million debris items larger than 1cm are currently orbiting the Earth ranging from screws and dead satellites to space rocket components. To address the issue of space congestion,  Read more…

EUSPA, the European Union Agency for the Space Programme: The start of a new era for EU Space

The European Union Agency for the Space Programme, EUSPA, was launched on 12 May marking the start of a new era for EU Space. Building on the legacy of the European GNSS Agency, EUSPA will take on more responsibilities to create even more opportunities from Space for EU citizens and its economy.

The adoption of the Regulation establishing the new EU Space Programme on April 27 marks a new beginning for the EU Space Programme and for the European GNSS Agency (GSA), which has now officially evolved into EUSPA, with an expanded mandate and new responsibilities.

Ten years of safer skies with Europe’s other satnav system

With 26 satellites in orbit and more than two billion receivers in use, Europe’s Galileo satellite navigation system has made a massive impact. But our continent has another satnav system that has been providing safety-of-life services for ten years now – chances are that you’ve benefited from it without noticing.

EGNOS

EGNOS

Its name is EGNOS, the European Geostationary Navigation Overlay Service. Transmitting signals from a duo of satellite transponders in geostationary orbit, EGNOS gives additional precision to US GPS signals – delivering an average precision of 1.5 metres over European territory, a tenfold improvement over un-augmented signals in the worst-case – and also confirmation of their ‘integrity’ – or reliability – through additional messaging identifying any residual errors.

Galileo satellite performs collision avoidance manoeuvre

Under the management of the European GNSS Agency (GSA), a collision avoidance manoeuvre for satellite GSAT0219 was performed during the first weekend of March. This manoeuvre was conducted following a collision risk alert received from EU Space Surveillance and Tracking (EUSST).

On 25 February, the Galileo Service Operator (GSOp) received from the EUSST a collision risk alert between GSAT0219 and an inert Ariane 4 upper stage launched in 1989. Following this warning, GSOp started to closely monitor the risk, in close cooperation with EUSST that was refining its predictions. Read more…

Galileo OSNMA tests underway

Galileo has started testing Open Service Navigation Message Authentication (OSNMA) in the signal-in-space, allowing the first-ever OSNMA-protected position fix to be successfully computed. Testing will continue over the next months, ahead of a so-called “public observation” phase. This is the first-ever transmission of authentication features in open GNSS signals of a global navigation system.

The Galileo OSNMA is an authentication mechanism that allows GNSS receivers to verify the authenticity of GNSS information, making sure that the data they receive are indeed from Galileo and have not been modified in any way. Read more…
