Galileo is the European Union's Global Navigation Satellite System (GNSS), managed by the European Union Agency for the Space Programme (EUSPA) with design and development by the European Space Agency (ESA). It provides highly accurate, guaranteed global positioning services under civilian control with improved positioning and timing information. Galileo offers various services, including an Open Service (OS) for mass-market use, a Search and Rescue (SAR) function, a High Accuracy Service (HAS), and a Public Regulated Service (PRS) for authorized users.

Un concetto di posizionamento, navigazione e sincronizzazione in orbita terrestre bassa è in fase di sviluppo per integrare i servizi esistenti di Galileo.
OSNMA is part of the Galileo Open Service and is available for free to all users.
Receivers that support OSNMA can verify that a signal truly comes from Galileo and reject counterfeit or reproduced signals.
With OSNMA, authentic Galileo messages can be reliably achieved under real-world conditions.
Galileo engineers adapted OSNMA to work reliably even in environments with high loss, allowing for authentication during intermittent reception.
For the first time, civil users can benefit from an operational, free message authentication service via Galileo OSNMA.
From 2016 to 2018, OSNMA functionality was included in the Galileo service baseline.
EGNOS v3 will enhance GPS and Galileo signal performance, providing even more precise and reliable navigation.
Every Galileo message contains a cryptographic signature that verifies its origin with OSNMA.
On July 24, 2025, Galileo officially became the first global navigation system to provide open authentication to its users.
A fundamental requirement is that receivers be synchronized with the time of the Galileo system to detect and reject reproduced data.
Currently, EGNOS operates only with GPS signals, but EGNOS v3 will include support for Galileo.
Rodrigo da Costa, Executive Director of EUSPA, stated that OSNMA increases the assurance of data authenticity from Galileo.
Galileo, the European satellite navigation system, includes a secure government service for institutional use.
The final flight of 2025 will transport two Galileo satellites into orbit aboard an Ariane 62 for the European Commission.
Galileo has been employed alongside GPS in Ukraine to improve resistance against electronic jamming.
Two Galileo satellites have safely arrived in Kourou in preparation for their upcoming launch on Ariane 6 #VA266.
HydroGNSS will compare reflected L-band microwave signals from navigation satellites like GPS and Galileo with direct GNSS signals.
Arianespace's last flight of 2025 will carry a pair of Galileo satellites to orbit aboard an Ariane 62 for the European Commission.
Both satellites are compatible with the Galileo navigation system and other Global Navigation Satellite Systems.
