1 War-Winning Capabilities On Time, On Cost Services-Based Testing of Autonomy 16 May 2018 Chris Eaton, Ph.D. Chief Engineer, ET-CTF DISTRIBUTION A. Approved for public release; Distribution is unlimited 412-TW-PA Integrity Service Excellence

2 Background Autonomy identified by DoD as technology priority Autonomy part of DoD Defense Innovation Initiative and 3 rd offset strategy Autonomy Community of Interest Test & Evaluation, Verification & Validation (TEVV) Strategy June 2015 Five Goals: Methods & Tools Assisting in Requirements Development & Analysis Evidence-Based Design and Implemenation Cumulative Evidence through Research, Development, Test and Evaluation (RDT&E), Developmental Testing (DT), & Operational Testing (OT) Run-Time Behavior Prediction and Recovery Assurance Arguments for Autonomous Systems Ranges need safety & performance assurance of Autonomy before operations

3 SBTA Approach Need to develop capabilities, methods, tools for Autonomy testing earlier Significant ongoing research at lower TRL levels Traditional DT TRL 6 and above normally Utilization of suas simpler integration, lower cost Existing manned & unmanned vehicles expensive to operate, more difficult to modify Diverse platform capabilities available AFRL developing Unmanned Systems Autonomy Services (UxAS) Open software & hardware architecture Integrate with suas autopilots JHU-APL Safe Testing of Autonomy in Complex, Interactive Environment (TACE) Provide Run Time Assurance (RTA) Watchdog Provide Live-Virtual-Constructive data injection

4 SBTA Architecture Utilize COTS capability where able UxAS and Services run on odroid, RaspberryPi or similar when able Existing autopilots and baseline control maintained for safety Communications challenge for longer range/beyond line of sight Segregation of baseline vehicle and services under test Allows focus on new services

5 SBTA UxAS Architecture

6 SBTA Control Scheme

7 SBTA Integration Baseline Aircraft Verification Provides test team with standard operations to work from Airworthiness Integration of UxAS Verify UxAS processors and software communicating properly with baseline aircraft Ensures ability to take over with RTA watchdog, ground control, and safety control Autonomy Integration Verification Installation of new autonomy service Primarily ground verification of communications Autonomy Performance Testing Determination/Verification of service performance Focus on Autonomy and not aircraft

8 SBTA UAS Integration Process

9 SBTA Potential Aircraft Provide spectrum of capability Speed, Sensor, Endurance Lynx basic TACE, Autonomy without sensor Penguin Spectrum of small sensors, longer endurance Arcturus Long Endurance, larger payload Swift Radioplanes Lynx UAV Factory Penguin Arcturus T-20

10 SBTA Implementation Currently integrating on Lynx Integration of basic autonomy processor Development of TACE RTA Watchdog & LVC Initial not UxAS compliant, UxAS integration starting soon Checkout of TACE RTA & LVC Summer 2018 Proof of onboard RTA capability Initial LVC simulation development Full integration with UxAS & multiple vehicles New contract with JHU-APL signed Initial integration approach started March 2018

11 Lynx SUT Functional Architecture 11

12 Photographs of the New Flight Payload Boards

13 Conclusion Open architecture allows wide range of integration options Significant cost savings over Large UAV and Manned aircraft Ongoing implementation and testing on Lynx Scalable approach for larger vehicles Cost-Effective, Scalable, and Efficient Autonomy Test Capability
