ADS-B Surveillance Separation Error Sensitivity AnalysisDecember 2009
Two efforts are currently examining Automatic Dependent Surveillance-Broadcast (ADS-B) separation requirements: a Federal Aviation Administration (FAA) group, titled the Separation Standards Working Group (SSWG); and a joint RTCA/EUROCAE group termed the Requirements Focus Group (RFG). Although coordinated efforts, the SSWG emphasis is on particular issues of concern to the FAA. The different assumptions made by each of these groups are examined, and results are presented in relationship to the different Monopulse Secondary Surveillance Radar (MSSR) reference models used in each comparative assessment. Sensitivity of resulting ADS-B separation requirements to the assumptions and scenarios used in determining these requirements is quantified for both Global Positioning System (GPS) no-fault and fault conditions.
