Global Navigation Satellite Systems Engineering, Policy, and Design
After years of development and large-scale testing, Galileo’s Open Service Navigation Message Authentication (OSNMA) is no longer an experimental signal but a fully declared service, confirming Galileo’s position as the world’s first civilian GNSS to provide cryptographically authenticated navigation data.

Resilient GPS (R-GPS), an experimental plan to add a proliferated layer of small navigation satellites on top of the core GPS constellation, has been terminated, according to reporting by SpaceNews. Early design work from multiple contractors will be used to inform future architecture decisions, but no on-orbit demonstrations are moving forward.
