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.

Raytheon is working on OCX upgrades expected to be delivered in 2022 that include hardened cybersecurity, anti-jam capabilities, and new software compatible with the military’s M-code and Europe’s Galileo global navigation system.
OCX Blocks 1 & 2 new features include an enhanced and expanded monitor station network for improved cybersecurity, improved anti-jam capability, enhanced operational capability to control modernized military signals, support for GPS III boosted earth coverage Military code (M-code), and monitoring of Galileo-compatible and safety-of-life signals.
Thales Alenia Space was previously selected to provide six satellites for the Galileo Second Generation constellation.
The European Union cooperates with the European Space Agency on the Galileo satellite navigation program and the Copernicus Earth observation satellite series.
OSNMA is being pioneered by the Galileo Program.
The Galileo Program is pioneering OSNMA technology.
The authentication of the Galileo signal using OSNMA technology is a notable achievement for Septentrio.
The first satellites of the Galileo 2nd Generation will be placed in orbit by the close of 2024.
The Galileo 2nd Generation satellites are designed to improve robustness to interference and jamming.
The Full Operational Capability phase of the Galileo program is managed and fully funded by the European Union.
The six satellites provided by Thales Alenia Space will be part of the 2nd Generation of the Galileo constellation.
The Galileo 2nd Generation satellites are designed to improve Galileo positioning accuracy.
Thales Alenia Space signed a €772 million contract with the European Space Agency acting in the name and on behalf of the European Union represented by the European Commission to provide six satellites for the 2nd Generation Galileo constellation.
The Galileo 2nd Generation satellites are designed to improve the resilience of Galileo signals.
The Galileo 2nd Generation satellites will use inter-satellite links.
Highly stable optical clocks combined with optical links are intended for future generations of satellite navigation systems such as Galileo and for new GNSS architectures like the Kepler concept developed at DLR.
Galileo satellites transmitted OSNMA authentication data for testing beginning on 18 November 2020 at 15:28 UTC.
The first OSNMA tests used eight Galileo satellites for around two hours on 18 November 2020.
OSNMA test transmissions use spare bits from the current Galileo navigation message and do not impact legacy Open Service receivers implementing the current OS Signal-In-Space Interface Control Document (OS SIS ICD).
OSNMA provides additional robustness to the Galileo signal intended to support applications where security and trustworthiness are a priority.
