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.
