GPS-denied environments aren't edge cases.
Test sensor fusion resilience under coordinated jamming and spoofing — the same attack signatures documented in active conflict zones and adversarial environments.
What fails in GPS-denied environments
Autonomous systems assume GPS is the ground truth. When it's not — through jamming, spoofing, or signal collapse — sensor fusion stacks reveal gaps that only show up under the right conditions.
📡
Sensor fusion fallback quality
When GPS is jammed, your system should fall back to IMU dead reckoning. But IMU drift accumulates fast. How long does position hold before error becomes mission-critical? Test it with a controlled, reproducible blackout.
🎯
Spoofed waypoint navigation
Coordinated spoofing pushes reported position off the real trajectory while satellite count and accuracy fields stay normal. A system that trusts the GPS fix executes waypoints against a false map.
⚠️
Multi-sensor collapse
Real adversarial environments often jam or degrade multiple sensors at once. GPS + barometer + magnetometer degradation simultaneously reveals which components of your fusion stack are truly independent.
Scenarios built for adversarial environments
These scenarios are modeled on interference signatures documented in active conflict zones and GPS-contested airspace. All replay deterministically — same scenario, same timeline, every run.
multi/conflict-zone Team
Conflict Zone
Simultaneous GPS jamming, IMU noise injection, barometer drift, and magnetometer anomaly — modeled on multi-sensor degradation patterns documented in active conflict zones. The definitive sensor fusion stress test.
Relevant for: sensor fusion, dead reckoning, anomaly detection
gnss/gulf-jamming-2026
Gulf Jamming 2026
Broadband L-band jamming causing total GPS signal loss over the Strait of Hormuz — one of the most documented jamming corridors in the world. Tests clean handoff to fallback navigation under hard signal denial.
Relevant for: GPS denial fallback, IMU hand-off, mission continuity
gnss/gulf-spoofing-2026
Gulf Spoofing 2026
Coordinated position spoofing — reported location shifts by up to 30 km while accuracy and satellite count remain normal. Tests spoofing detection logic and whether your system acts on a false GPS fix.
Relevant for: spoof detection, position validation, waypoint integrity
multi/magnetic-anomaly Team
Magnetic Anomaly
Simulates magnetic interference — compass heading drifts by up to 90° over 60 seconds. Tests whether your fusion stack's heading estimate degrades gracefully or causes abrupt course corrections.
multi/everything-fails Team
Everything Fails
GPS, accelerometer, gyroscope, barometer, and magnetometer all degrade simultaneously. The maximum-stress test for any autonomous navigation stack operating without external positioning infrastructure.
Deterministic, reproducible, scriptable
Every scenario replays the same timeline, at the same intervals, with the same sensor values — every time. No hardware required in CI. Write your own scenarios with precise control over every injection parameter.

}Enterprise — for custom scenario authoring and SLA
Defense and autonomy teams often need custom interference signatures, multi-day support SLAs, and invoiced contracts rather than self-serve monthly billing. The Enterprise plan covers all of this — including help authoring scenarios from your own field data or interference specifications.
Find the GPS-denied failure modes before the field does.
