CNS Modeling & Simulation

Developed by NASA for Simulating the physical movement of aircraft in the NAS

Simulates NAS entities (ATCSCC, ARTCC, TRACON ATC, Airport ATC, Aircraft).
Simulates NAS ATM operations (TFM, CDR, Separation rules, Sector restrictions, etc).
Enables testing of alternative roles and forecasting methods for ATM Command and Control.
Models the dynamic interaction between NAS Agents.
Used for analyzing Airspace Concepts; developing decision support and automation tools.
Fast-time, nationwide simulation can include one to thousands of flights.
Full flight schedule with flight plans, 4-D gridded winds, gate-to-gate operations.
High-fidelity 4-D aircraft trajectory models; aircraft physical models; pilot-based control.

Developed at GRC to add CNS functions into ACES Simulation Environment

CNS enhancements added during development for realistic Flight / ATC / ATM / CNS interactions.
Models include: VHF/Voice, CPDLC over VDL2, GPS and VOR/DME Nav, SSR and ADS-B Surv
Generates detailed CNS system performance data in NAS-wide, air traffic environment.
Provides flexibility for integration of new models (process already established).
Fully configurable for Aircraft/CNS System equipage and varying CNS system parameters.
Takes full advantage of ACES functionality including NAS Entities and ATM/Flight Operations.
