  • Detect and AvoID Alerting Logic for Unmanned Systems (DAIDALUS) is a collection of algorithms for a detect and avoid concept that supports the integration of Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS). DAIDALUS algorithms are based on a mathematical definition of the well-clear boundary. The following algorithms are implemented in DAIDALUS.

    DAIDALUS algorithms have been formally specified and verified for functional correctness in PVS[*]. The PVS formal development is part of the NASA PVS Library. Furthermore, implementations of DAIDALUS algorithms in Java and C++ are available under NASA's Open Source Agreement:

    DAIDALUS is included in Appendix G of RTCA/FAA Minimum Operational Performance Standards (MOPS) DO365 for detect and avoid of unmanned aircraft systems (UAS) by RTCA Special Committee 228.
