GPS is accurate but noisy. IMU is smooth but drifts. Sensor fusion (Kalman Filter) combines both — getting smooth, accurate positioning. Every autonomous vehicle and drone does this 100+ times per second.
Read: Sensor Fusion →What you can do here
- Crank up the GPS noise and watch the fused estimate stay stable
- Let the IMU drift alone and see how fast dead reckoning falls apart
- See why neither sensor alone is good enough for a real robot
