OSNMA test signals are being broadcast by the Galileo constellation

Tests of Galileo OSNMA underway

11 February 2021
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.

Galileo in the permanent CORS network in Sweden: a success story

09 February 2021
SWEPOS is the CORS network for satellite positioning in Sweden. From the introduction of Galileo in its service in 2018, the network users have observed higher availability and better performances, especially when using a high cut off angle or in harsh environments. Connections to SWEPOS network have increased rapidly, and the number of Galileo users in the region continues to grow.
The workshop will gather GSA and Member States representatives and is open to anyone interested in GNSS.

Galileo Workshop 2021: All you need to know about the performance of Europe’s Global Navigation Satellite System

01 February 2021
The Galileo Performance Workshop 2021 led by the European GNSS Agency will offer an in-depth analysis of the performance of Galileo and how it is evaluated for users.
Happy birthday Galileo Search And Rescue (SAR) Return Link Service!

Happy birthday Galileo Search And Rescue (SAR) Return Link Service!

27 January 2021
A year after declared operational, the Galileo Return Link Service has been exceeding the performance levels committed in the SAR/Galileo Service Definition Document. With the recent upgrade in its European ground facilities, Galileo SAR is leading the way as an important component of the International Cospas-Sarsat Programme.
The IPS anticipates any degradation of performance, allowing operators to put in place mitigation measures in good time.

New EC service monitors ionosphere for GNSS users

13 January 2021
Ionospheric effects can be a major source of disruption to GNSS signals, so it is important to be able to predict and compensate for these disturbances. With this in mind, the European Commission-funded Galileo Ionosphere Prediction Service (IPS) monitors ionospheric activity and informs GNSS users in good time of an upcoming event that could disrupt GNSS signals and applications.
The updated OS SIS ICD is available for download on the GSC website.

Updated Galileo OS SIS ICD now available

11 January 2021
We are pleased to announce the release of the new Galileo Open Service Signal in Space Interface Control Document (OS SIS ICD v2.0). This second issue of the document is available for download in the Programme Reference Documents section of the European GNSS Service Centre (GSC) web portal.

Q3-2020 Galileo Performance Reports are now available!

17 December 2020
Galileo OS and Enhanced SAR/Galileo Service Performance Reports of the third quarter of 2020 (covering July, August and September) are available under the Electronic Library of the European GNSS Service Centre web portal.
Timing is everything – GNSS and the energy grids of the future

Timing is everything – GNSS and the energy grids of the future

16 December 2020
In the smart energy grids of the future, all energy market participants will communicate with each other, making energy supplies more reactive. This will bring many benefits, including reduced costs, improved efficiency and the seamless integration of the distribution of energy sources, including renewable energy. However, for smart grids to operate successfully they will have to be based on a solid and robust synchronisation infrastructure. This is where GNSS comes in.
Let us have your feedback on Galileo/EGNOS

Let us have your feedback on Galileo/EGNOS – User satisfaction survey launched

15 December 2020
The European GNSS Agency (GSA) is launching the 2020 editions of its Galileo User Satisfaction Survey and EGNOS User Satisfaction Survey. These surveys play an important role in the evolution of the EGNSS programmes by feeding users’ needs and requirements into programme development.

Further information on the event of 14th December

15 December 2020
The Galileo system was returned to its nominal state a few hours after the incident which occurred between 00:00 and 06:00 on Monday morning 14 December. This service incident is still under investigation. It is confirmed to be related to an abnormal behaviour of a ground atomic clock in the time determination function of the system. The time synchronisation and orbit determination algorithms immediately flagged the data as MARGINAL (SISA*=NAPA**) before it affected the quality of the measurements.
