An experimental satellite has mapped the scale of GPS jamming across Europe and the Middle East from space for the first time.

The data surprised the team behind the project and indicated that satellites orbiting far from Earth aren't the only ones that experience degradation of their positioning, navigation and timing (PNT) signals, which could affect their performance and the safety of their operations.

The new measurements were made by Pulsar-0, the first satellite of the novel Pulsar navigation constellation developed by California-based Xona Space Systems.…
