GNSS
The general term for satellite constellations that provide positioning, navigation, and timing worldwide, including the U.S. GPS, Europe's Galileo, Russia's GLONASS, and China's BeiDou. GNSS signals are extremely weak at the receiver, which makes them vulnerable to interference.

Why it matters
GNSS is the shared source of position and precise time that countless systems assume will always be there; when it is denied or spoofed, the failures cascade far beyond navigation.
