ADS-B Monitoring

The ADS-B Monitoring Project covers these activities: 

  • monitoring the ADS-B 1090 MHz ES equipage evolution;
  • monitoring the content and quality of ADS-B 1090 MHz ES airborne data (using ADS-B 1090 ES, multilateration and radar data).

Whilst an assessment of the ADS-B v2 aircraft is currently of particular interest, the performance and capabilities of other (ADS-B v0 & v1) aircraft are also assessed. The information derived from the analysis carried out in the ADS-B Monitoring Project not only helps to identify and resolve avionic anomalies but also leads to a good understanding of the current performance and configuration of ADS-B equipped aircraft.

This information will also be used to see how equipage trends evolve, following the publication of ADS-B related mandates by the European Commission and other parties. It can also be used, as appropriate, to support certification activities.

ADS-B Monitoring Project analysis

The analysis is based on a comparison of the ADS-B 1090 MHz ES reported data with a reconstructed reference drawn from multi-radar data, derived from four overlapping radars used for airborne performance and multilateration (MLAT) data for airport performance. This data comes from these ADS-B Out monitoring sites:

  • EUROCONTROL Experimental Centre Brétigny (Paris), France ;
  • Toulouse, France (DSNA);
  • Plans are in place to receive data from Brussels, Belgium (Belgocontrol) and the Maastricht Upper Area Control Centre (MUAC), the Netherlands (EUROCONTROL).

ADS-B Monitoring Project tools

The tools used in this analysis are currently based on SASS-C (ADS-B and Radar) and the AVTool, modified to process MLAT, GPS, track and ADS-B data as well.

The analysis results are compared to the requirements of the airborne segment in the relevant standards and certification documents such as: EUROCAE ED-126, EASA AMC 20-24 for ADS-B NRA, EASA CS–ACNS and FAA AC20-165A for ADS-B RAD.

Project partnership

The ADS-B Monitoring Project cooperates with all relevant stakeholders - airframe manufacturers, avionics manufacturers, ANSPs etc. - in resolving any avionic anomalies identified. Information on such anomalies and performance assessments is exchanged with European and other international ADS-B implementers.

The activities of the ADS-B Monitoring Project are complementary to those of the Surveillance Avionics Functional Performance Analysis (SAFPA).

ADS-B Monitoring Project activities are held to be key in supporting the operational introduction of modernised Surveillance right across Europe.
