Webinar: Galileo High Accuracy Service (HAS) and Open Service Navigation Message Authentication (OSNMA)

27. September 2023, 9:00 - 12:00
Vienna, AT

In this webinar, high-level speakers from the European Space Agency (ESA), European Commission (EC) and the European Union Agency for the Space Programme (EUSPA) will present an up-to-date overview on the status of Galileo and developments concerning HAS and OSNMA. The objective is to gain awareness of the benefits of Galileo HAS and OSNMA in interested GNSS communities around Europe.


The webinar is being held as part of the GARFIELD project – "New GNSS services and innovative processing processes for target group-specific applications". The project is funded by the Austrian Space Applications Programme (ASAP), managed by the Austrian Research Promotion Agency (FFG) on behalf of the Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation and Technology (BMK).


Content Description

With Galileo, Europe has the first satellite navigation system under civilian control. The newly introduced Galileo High Accuracy Service (HAS) and Open Service Navigation Message Authentication (OSNMA) bring key benefits to the users that other GNSS cannot offer.

  • HAS provides free of charge high accuracy Precise Point Positioning (PPP) corrections through the Galileo signal (E6-B) and by terrestrial means (Internet). Galileo HAS offers real-time improved user positioning performances down to a decimeter level.
  • OSNMA represents an authentication mechanism that allows a GNSS receiver to verify the authenticity of the GNSS information and of the entity transmitting it, to ensure that it comes from a trusted source.

Both, HAS and OSNMA are a free-of-charge service.
