- GPS signal jamming around Ukraine is affecting satellites up to 1,200 miles above Earth.
- Russia and Ukraine are using powerful signals to interfere with precision weapons and drones, impacting space environments.
- LEO satellites, like those in SpaceX's Starlink, rely on GPS for timing and positioning, crucial for operations.
- GPS jamming and spoofing are becoming common in conflict zones, affecting aviation, maritime traffic, and satellites.
- The Pentagon is expanding its use of LEO satellite constellations, increasing funding to $13 billion.
- GPS timing is essential for global systems like finance, power grids, and the internet, but its vulnerability is a concern.
- Anti-jamming technologies like CRPAs are being developed to mitigate interference, though advanced models are export-controlled.
- New GPS III satellites with M-Code signals offer stronger, encrypted signals resistant to jamming and spoofing.
- Future GPS upgrades include regional military protection (RMP) to focus signals over smaller areas for increased strength.
- The Space Force is exploring alternatives like quantum inertial positioning, but no single solution can replace all GPS services.
