Estimate UAV hover error from GPS, barometer and wind effects.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Hover accuracy | Horizontal error from variance | UAV flight control |
| GPS error | 2–5 m SPP, cm-level RTK | GNSS principles |
| Attitude error | ±0.5–2° pitch/roll by model | Flight controller |
| Wind disturbance | Displacement ≈ v × response time | Flight control theory |
| Circular error probable | CEP50 radius for 50% probability | Navigation statistics |
| Sensor fusion | IMU+GPS+vision complement | Sensor fusion |
