J-HATT is a new unmanned aircraft system (UAS) ground control station (GCS) that HATS developed for NASA. It is designed to significantly augment NASA’s current simulation capabilities, as well as to become an industry standard for UAS GCS used in the national airspace.

J-HATT supports manual control of one or a few UAS. It has all the critical functions for controlling UAS along with the recent Detect and Avoid (DAA) displays and symbols developed by UAS-in-the-national airspace systems (NAS) project. Additionally, J-HATT integrates with NASA’s Live Virtual Constructive – Distributed Environment (LVC-DE) and operated in shadow mode in a flight test conducted in July 2015 at NASA Armstrong.


HATS has completed the following tasks:

  1. Defined M-HATT features, including research planning, aircraft control modes, waypoint information, 2D map settings, PFD, data collection and analysis capabilities, collision avoidance, keyboard/mouse modality, caution warning advisory system, and save/import/export settings;
  2. Reviewed UAS-in-the-NAS’s Human Systems Integration (Piloted DAA Self-Separation Traffic Display and Alerting Evaluation) and developed and incorporated into J-HATT the experiment display conditions: Basic, Advanced, Standalone, and Integrated;
  3. Implemented and formatted sample messages exchanged between J-HATT and other LVC-networked components according to 4586 standards;
  4. Developed connectivity (i.e., sending and receiving data) between J-HATT and LVC-DE server’s clients such as Multi-aircraft Control System (MACS), Cockpit Situation Display (CSD), and live aircraft; and
  5. Demonstrated connectivity in shadow mode during NASA’s UAS-in-the-NAS Flight Test 3 at NASA at Armstrong Flight Research Center.
