Around a hub like Barcelona, most of what is overhead is routine: airliners and cargo aircraft on published arrival and departure procedures, general aviation, and helicopters. AeroScope is observer-relative — instead of asking “where is flight X,” you fix the map on Barcelona and it continuously evaluates everything above it. Each aircraft carries a transparent 0–100 attention score built from eight rule-based factors (emergency squawk, military hex allocation, proximity, altitude and speed anomalies, loitering patterns and integrity-check failures), so the one worth a second look rises to the top instead of hiding in the traffic.
Spoofed or self-inconsistent broadcasts are flagged too: AeroScope runs a DO-260B integrity check (NIC/NACp/NACv/SIL), a Kalman normalised-innovation test and geometric-versus-barometric altitude residuals, and only raises a flag when at least two independent detectors agree.
