In July 2010, Cassidian installs a cooperative collision avoidance system based on Traffic Alert and Collision Avoidance System (TCAS) onboard the Barracuda Unmanned Aerial System (UAS) demonstrator.

    The “Sense&Avoid” capability is a key challenge, even when only considering operation in air space classes A–C. For that reason, the demonstration is intended as a risk mitigation measure to support future UAS development efforts.

    The demonstration steps involve a laboratory test with real equipment in a closed-loop demonstration and the automatic execution of a collision avoidance manoeuvre in flight. The in-flight demonstration takes place in segregated air space involving the Barracuda demonstrator platform and a real intruder.

    The section outlines the setup of the cooperative collision avoidance system demonstrator, including the interface with the flight control system of the Barracuda and the control authority granted to the cooperative collision avoidance system demonstrator.

    It summarizes the Human-Machine-Interface (HMI) layout and situation awareness provided to the UAS operator and illustrates how the potential loss of data link connection is covered by the system design.

    The paper details the development process applied, including requirements definition, validation, and verification steps as well as hardware-in-the-loop demonstration in support of the in-flight demonstration.

    It illustrates the demonstration scenarios utilized in the flight demonstration and the results achieved.

    Finally, the paper draws conclusions regarding the potential of such cooperative collision avoidance systems based on TCAS, the operational implications and the certification aspects to be solved.
