Information Management Framework

Extensible system

  • Supports multiple tower positions
  • Adaptable to sites and different class airports

Flexible information architecture

  • Enables integration with current and planned NAS systems

Evolvable system – replaceable components

Net-Centric architecture is key to providing integrated system

Based on SWIM guidelines

  • Enables data sharing with other facilities

Concept validation platform

  • Enabler for validating ongoing FAA data modeling

  • Surveillance Processor

– Combine ASDE-X dropped or split track data into single consistent track using multiple sensor reports – Smooth aircraft position and heading using Kalman Filter models – Handle high rate of ASDE-X reports – Extend tracks to 60nm

  • Surface Monitor

– Locate targets relative to surface features (runway, taxiway…) – Determine if aircraft is airborne or on ground – Model vehicle motion and predict position in near-future – Control runway entrance/threshold hold bars – Generate safety alerts

  • Target Broker

– Match data within and between different external data sources (ASDE-X, FDIO, TFMS…) – Provide unique and consistent identifier for flights within TFDM system

Data Fusion

Operational algorithms for identifying, tracking, and locating targets
