Map Center Display only
Where the SVG chart is centered for the operator. Purely visual — NOT the projection center for sensors.
System Reference Point SRP — Required
Center of the stereographic projection used by the tracker (ARTAS / Leonardo MRT [SYSTEM_CENTER]). Used by all sensors with reference plane = SYS to convert x,y plots into lat/lon.
Runways 0
Physical runway thresholds (WGS-84, landing threshold — displaced if applicable). Single source of truth for landing detection and approach geometry. Designator, QFU and length are derived from the two thresholds, never stored separately.

Sensors 0
Radar / SMR / MLAT / ADS-B / ARTAS sensors. Used for x,y → lat/lon conversion (sensors with reference plane = SENSOR) and for track timeout (= scan period × timeout scans).
Vehicle ICAO Ranges
Hex ICAO-address ranges (inclusive both ends) classified as ground vehicles instead of aircraft.
