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.

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.

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.

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.

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.

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.

14 December 2020 The Galileo Service was affected from Dec 14, 00:00 UTC by an anomaly in the time determination function of the ground segment of the system.
This resulted in signals flagged as MARGINAL (SISA=NAPA) for all satellites. During this period, pseudorange errors in excess of nominal performance were experienced by user receivers.

03 December 2020 Earlier in November, the International Civil Aviation Organization (ICAO) approved new Standards and Recommended Practices (SARPs) paving the way for the development of new Dual Frequency Multi-Constellation Satellite Based Augmentation Systems (DFMC SBAS).

30 November 2020 The 3rd edition of the User Consultation Platform (UCP) for the European Space Programme will take place on 1-2 December, ahead of European Space Week 2020. This is a unique opportunity for the rapidly expanding community of space tech users to inform the organisations and institutions that oversee the programme of their experience and requirements, helping to shape the future evolution of the system.
