Imagine piloting a high-tech drone, only to have its navigation system hijacked by an invisible enemy. This isn't science fiction; it's the chilling reality of GPS spoofing and denial-of-service (DoS) attacks, posing a critical threat to modern militaries reliant on unmanned aerial vehicles (UAVs).
Not yet do we see drone-on-drone aerial dogfights. Today's battlefields are dominated by silent UAVs, eyes in the sky gathering intel and delivering precision strikes. But their effectiveness hinges on accurate navigation, often solely provided by GPS. Just like your phone, these drones rely on satellite signals for positioning, making them vulnerable to manipulation.
Enter the nefarious world of spoofing. Malicious actors can mimic GPS signals, broadcasting false data that throws the UAV's navigation system off course. Imagine your drone being tricked into thinking it's miles away, potentially flying into enemy territory or missing its target by a devastating margin.
DoS attacks take a different approach, overwhelming GPS satellites with jamming signals, essentially blinding the drones to their true location. This can render an entire fleet of UAVs useless, crippling reconnaissance and attack capabilities.
So, how are militaries fighting back in this fog of GPS warfare? Here's a glimpse into their arsenal:
1. Diversifying the Drone's Senses: Moving beyond GPS, militaries are equipping UAVs with a multi-sensory navigation suite. Inertial Navigation Systems (INS) use internal sensors to track movement, while terrain-matching algorithms compare real-time imagery to onboard maps. Celestial navigation, an age-old technique, utilizes the stars as celestial beacons. Each method has its limitations, but their combined data paints a more accurate picture, making it harder to fool the drone.
2. Redundancy and Fault Tolerance: Just like having a spare tire, militaries are equipping drones with multiple GPS receivers and INUs. If one is spoofed or jammed, the others can still provide some level of navigation, preventing complete blackout. Ground-based radio systems can provide location abilities at strong signal strengths, like the British Gee navigation system for bombers in WW2.
3. Advanced Spoofing Detection: Gone are the days of simply trusting the GPS signal. Militaries are developing sophisticated algorithms that can sniff out fake signals by analyzing signal strength, satellite geometry, and even subtle inconsistencies in the data.
4. Cooperative Navigation: Imagine drones sharing navigational data like a flock of birds. This is the essence of cooperative navigation, where UAVs use information from each other to cross-check their positions and identify anomalies. This not only bolsters individual drones but also creates a resilient network that's harder to disrupt.
The battle for GPS supremacy is far from over. As technology advances, so too will the sophistication of spoofing and jamming techniques. But by diversifying their navigation toolbox, embracing redundancy, and developing advanced detection and cooperation strategies, militaries are taking crucial steps to ensure their UAVs remain sharp-sighted even in the fog of GPS warfare.

This was written by Bard from lengthy prompts, following reports of the failure of American precision munitions on the Ukraine-Russian front due to Russian GPS jamming/spoofing. I also asked Bard to write this in the style of "Foreign Affairs" or "The Economist" - for a slightly less breathless piece - but the result was too boring to share with you.
