GPS integrity map
How position quality shows up on ADS-B, and where to inspect it on the live RADARX24 map.
What you see on the map
RADARX24 plots aircraft using latitude and longitude from ADS-B broadcasts. When GNSS coverage is degraded, some tracks may drift, jump, or disappear until the transponder reports a fix again. Use the live map to compare traffic density with unusual movement patterns — this page is a guide, not a certified integrity chart.
NIC in plain language
NIC (Navigation Integrity Category) is a number carried in ADS-B that describes how trustworthy the reported horizontal position is. Higher NIC generally means the aircraft navigation system believes its fix is more accurate and less likely to be wrong without warning.
- High NIC — typical cruise over open areas with good satellite visibility.
- Lower NIC — more common near interference, jamming-prone regions, or sensor limitations.
- Missing metadata — many public feeds do not expose NIC per target; position may still plot normally.
