Standard published for remote activation of aircraft distress tracking beacons using the Search and Rescue (SAR) Return Link Service as offered by Galileo

11 March 2021

The EUROCAE “ED-277 - Minimum Aviation System Performance Standard for Aircraft Emergency Locator Transmitter Remote Command Via Return Link Service”  has been published and is available. It describes the characteristics of remote command via the Return Link Service for Emergency Locator Transmitter Distress Tracking  - ELT(DT) - in particular for remote beacon activation and deactivation. Today, only Galileo provides Return Link capability.
Galileo satellite performs collision avoidance manoeuvre

10 March 2021

Under the management of the European GNSS Global Navigation Satellite System Agency (GSA), a collision avoidance manoeuvre for satellite GSAT0219 was performed over the past weekend. This manoeuvre was conducted following a collision risk alert received from EU Space Surveillance and Tracking (EUSST).
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

9 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.
Galileo Workshop 2021: All you need to know about the performance of Europe’s Global Navigation Satellite System

1 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!

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.
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

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.
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. However, the incorrect data was still uploaded to the satellites. User receivers that do not process the health and status flags, or that keep MARGINAL satellites as part of the position solution computation, may have experienced large positioning errors. The following plots present the status of the various satellites during the event and provide an estimation of the typical pseudorange errors (***) experienced by users if processing the satellites, despite being flagged as MARGINAL.
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.
