An experimental satellite has mapped GPS jamming across Europe and the Middle East, revealing a larger scale of interference than expected. The findings highlight vulnerabilities in GNSS signals and the need for more resilient navigation systems.
An article from Inside GNMS describing how GPS broadcasts a mysterious numbers station-like signal from what appeared to be an empty field.
An interactive article breaks down how GPS works—from turning nanosecond signal delays into distance, to trilateration with satellites, and even Einstein’s relativistic corrections.
