The European Space Agency officially announced testing of Galileo’s Open Service Navigation Message Authentication (OSNMA) in its signal-in-space, allowing the first OSNMA-protected position fix to be successfully computed. This is the first-ever transmission of authentication features in open signals of a GNSS.

Surrey Satellite Technology Limited (SSTL) of Guildford, UK, shipped the last of the Galileo navigation payloads under its manufacture at the end of November 2020, the European Space Agency (ESA) stated. As a consequence of Brexit, the UK will no longer participate actively in Galileo.

According to a statement on the UK Government’s official website, as of January 1 the United Kingdom will cease participation in the European Galileo and European Geostationary Navigation Overlay Service(EGNOS) programs. British citizens and other private users are not affected, apparently: “devices that currently use Galileo and EGNOS, such as smart phones, will continue to be able to do so.”

Pursuant to the 6-hour Galileo system outage on December 14, the European GNSS Agency (GSA) issued an update stating that the “service incident,” while still under investigation, “is confirmed to be related to an abnormal behaviour of a ground atomic clock in the time determination function of the system.”

On Monday, December 14, the EU’s Galileo program posted an official notice advising users that Galileo service was degraded on all satellites until further notice. Nominal service was then resumed about six hours later.

A satellite launching in November will use GNSS – Radio Occultation (GNSS-RO) to collect highly accurate global temperature and humidity information as an aid to more accurate and more advanced weather forecasting. Developed by NASA’s Jet Propulsion Laboratory (JPL), the spacecraft’s GNSS-RO instrument tracks GNSS satellite signals to measure the physical properties of Earth’s atmosphere.
