Unmanned Aircraft System

The vendor required to provide unmanned aircraft systems (CUAS) capability that delivers detection, identification, monitoring, and tracking (DIMT), with integrated informed decision support, to support airspace situational awareness.
- Requirement:
•    Rapid establishment of an operationally available DIMT capability to meet immediate mission requirements, including readiness by June 1, 2026.
•    Establishment of a flexible, open, and governable technical foundation that supports long-term transition toward government-owned infrastructure and institutional capability.
•    To achieve these objectives, the scope includes DIMT architecture design, system integration, deployment, configuration, testing, documentation, and technical sustainment services. 
•    Managed services are limited to system configuration, integration, maintenance, sustainment, and advisory support.
- Technical requirements
1. Detection modalities and coverage
•    Situational awareness: DIMT capability provides continuous airspace situational awareness in defined AOCs. 
•    Primary modality: rf-based detection provided as the primary baseline modality for initial operations. 
•    Multi-layered design: system architecture supports a multi-layered detection approach. 
•    Urban topology: system design explicitly accounts for urban topology, building density, and rf congestion. 
•    Rf limitations: explicit documentation of rf-centric detection limitations provided.
•    Future integration: architecture includes interfaces to support future integration of additional modalities
2. Urban performance validation
•    Prior performance: evidence provided of prior system performance in dense urban environments (>50 structures/sq km). 
•    Detection metrics: documented detection probability metrics provided for urban environments. 
•    False alarm data: documented false alarm and false track rate performance data provided. 
•    Real-world data: performance evidence derived from real-world deployments, not exclusively laboratory testing.
3. Monitoring, tracking, and multi-target performance
•    Continuous tracking: system provides continuous tracking capability for detected targets. 
•    Track continuity: system maintains ≥80% track continuity for targets within the area. 
•    Track drops: signal dropouts of <10 seconds are bridged and do not generate new track ids.
•    Multi-target: system tracks ≥10 simultaneous unmanned aircraft system (UAS) targets per area without degradation.
•    Update rate: system provides a track update rate of ≥1 HZ (one update per second).
4. Identification, remote id, and discrimination
•    Discrimination: system supports discrimination between authorized, unauthorized, and cooperative UAS 
•    Remote id logic: remote id data is treated as an advisory input (not sole source). 
•    Coverage plan: remote id coverage plan provided for each area (radius and altitude). 
•    Integrity: system includes logic to detect remote id anomalies and spoofing (e.g., impossible motion). 
•    Authenticated id: system supports authenticated UAS identity and integration readiness.
5. Deployment, infrastructure, and operations
•    Sustainment: contractor provides full technical sustainment (maintenance, calibration, health monitoring). 
•    Library transparency: "supported threat library" provided listing detectable makes/models/protocols. 
•    Library management: versioned rf library management supported with 15-minute rollback capability.
•    Redundant comms: mobile assets equipped with redundant communications (e.g., cell + sat/alt). 
•    Local buffering: mobile assets support "local-only" buffering (≥4 hours) during backhaul failure.
