Prognostic Airspace Virtual Lab

Edge UAV

The Prognostic Airspace Virtual Lab is a collaboration between multiple labs at NASA Ames Research Center and NASA Langley Research Center for the development of UAV and airspace prognostics technology. The members of the virtual lab conduct joint experiments involving UAVs, virtual aircraft, and hardware-in-the-loop elements to aid with the development and testing of new technologies for prognostics.

Virtual Testbed Infrastructure

The virtual testbed infrastructure supports dynamic live distributed experiments incorporating one or more real aircraft, virtual aircraft, and hardware-in-the-loop elements. The NASA developed LVC Gateway is used to facilitate live communication between testbed assets, and has been extended to support additional message sets for sensor data and prognostic results. A research framework is being developed to support live cloud based testing of prognostic tools. Additionally, the testbed infrastructure includes logging, traffic generation, and web-based displays to aid researchers.

Enabled Research

This infrastructure enables a number of research avenues for the team, including:

  • Airspace experiments with interaction between live and virtual (simulated aircraft). With this one could test conflict detection and avoidance, without risking loss of the aircraft
  • Hardware-in-the-loop fault injection: Experiments where a hardware-in-the-loop element is loaded to match the live condition of a real UAV. This will allow the testing of diagnostic and prognostic algorithms and decision making tools. The fault-injected components can even be run to failure, without risking the aircraft.
  • Exploration of future air traffic management concepts that include real-time prediction of airspace safety using a mix of real and simulated aircraft.
  • Using the playback agent to put an aircraft in repeatable traffic scenarios, such as one of a recorded historical traffic situation. This could be used to test new technology in difficult real-life scenarios, or replay aviation incidents.
  • Experiments integrating hardware-in-the-loop elements with virtual aircraft for testing prior to integrating live elements.
