A-PNT Position Accuracy
Dynamic position accuracy varies by latitude. Iridium satellites have closer spacing at higher latitudes, resulting in improved accuracy nearer the poles.
| Location | Latitude | Median Accuracy | 95th/97.5th Percentile |
|---|---|---|---|
| Norway | 69° N | 25 m | <50 m (95%) |
| Red Sea | 19° N | 42 m | <200 m (97.5%) |
