Future Aeronautical Subnetwork Traffic Emulator – CNS (FASTE-CNS)

www.faste-cns.com

Accelerating CNS


Background

Need for effective tools to model and analyze existing communications loads, and plan for required communications capacity in future

NASA initiated Virtual Airspace Modeling and Simulation (VAMS) project

NASA GRC leading the effort to integrate Communications, Navigation and Surveillance (CNS ) tools to be part of the Virtual Airspace Simulation Technologies (VAST) toolbox

As part of VAMS and VAST efforts NASA sponsored the development of Future Aeronautical Sub-networks Traffic Evaluator (FASTE) for CNS System – Beta tested in 2003

GRC developed Software Requirements Specifications for CNS models

FASTE Enhancements for CNS

Enhancements support pre- and post-trial analysis for OpCons– Pre-trial: Communications data input into current

FASTE-CNS system– Post-trial: OpCons simulation data used to perform

analysis Communications models - Medium fidelity

– Model voice, ACARS, and VDL Mode 2 media– Pre-trial results are available using the current version of

FASTE-CNS with GUI enhancements– Post-trial analysis will use data collected from the

operational simulation conducted in the ACES environment. Enhanced FASTE comm simulation model will provide the impact of comm on the OpCon.

Accelerating CNS



Navigation model - Low fidelity– Data collected from the operational simulation conducted

in the ACES environment used to model GPS and VOR/DME reported positions throughout the flight.

– Enhanced FASTE simulation model will provide occurrences of separation criteria violations.

Accelerating CNS



Surveillance model - Medium fidelity– Data collected from the operational simulation conducted

in the ACES environment used to model Secondary Surveillance Radar (SSR) and Automatic Dependent Surveillance - Broadcast (ADS-B) reported positions throughout the flight.

– Enhanced FASTE simulation model will provide occurrences of separation criteria violations.
