Overview GNSS interference can change rapidly. Understanding the operating environment therefore requires more than identifying where GNSS quality is currently degraded. Analysts also need to understand when conditions changed, how quickly they changed, and how those changes developed geographically over time. Using Atlas, a change in GNSS quality was observed in a cell on the

Overview Modern aircraft tracking relies heavily on ADS-B position reports, delivering unprecedented visibility across the globe through satellite-based surveillance networks. However, in regions where GNSS performance may be degraded or where navigation environments become more challenging, analysts often need additional tools to assess the reliability of reported aircraft positions. This case study demonstrates how Atlas,

The Atlas approach Analysts first used Atlas to review aircraft operating within the area of interest. Three aircraft were identified for further examination. Using the Aircraft Details page, analysts reviewed: ADS-B signal quality indicators VECTOR-derived positioning Historical aircraft behaviour Recent flight activity The analysis quickly showed that only one of the three aircraft was reporting
