Kp index indicates geomagnetic activity. Elevated values can affect GNSS accuracy and compass reliability in some conditions.
Practical impact
- Higher Kp may correlate with GPS position drift or loss;
- Magnetic interference compounds near structures regardless of Kp;
- RPAS relying on GNSS should monitor for positioning anomalies.
Context
Kp is supplementary information. It does not replace aviation risk assessment or regulatory checks.
