Background
Background (FASTE-CNS)

  • 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
