Preliminary Ontological Structure for Unmanned Aerial Vehicles
Michael D. Moskal II & William C. Hughes
Outline
• Existing ontologies• Class definitions– Platform Qualities– Sensor Qualities
• Ontology Overview• Potential Applications• Extensions and Future Work
Objective: Develop an extensible ontology to classify and maintain a list of features for unmanned aerial vehicles
Existing Ontologies

Preece, A., An Ontology-Based Approach to Assigning Sensor Tasks. 2007.
Benjamin Schumann, J.S., Hans Fangohr, Mario Ferraro, A Generic Unifying Ontology for Civil Unmanned Aerial Vehicle Missions, 2012, American Institute of Aeronautics and Astronautics.
• Matches sensors to task for ISR (Intelligence, Surveillance, and Reconnaissance) Missions• Very limited scope and focuses
heavily on sensor capabilities
Platform Selection

MQ-1 Predator MQ-1C Grey Eagle RQ-4 Global Hawk RQ-5 Hunter
RQ-11 Raven RQ-170 Sentinel QF-4 Phantom ScanEagle
MQ-9 Reaper CQ-10 Snowgoose MQ-8 Fire Scout K-Max

Ontology Rules
• Platform Rules• Platform prescribes some Design Quality• Platform has_quality some Effective Quality• Platform has_equipment exactly 1 Navigation Device• Platform has_equipment exactly 1 Communication Device• Platform has_equipment some (Dispensable Equipment or Non-Dispensable
Equipment)
• Logic Rules• has_equipement Kinetic Weapon Equivalent To High Speed Attack UAV• High Speed Attack UAV Equivalent To has_function High Speed Attack

Mission Readiness Tool
• Given a fleet of UAVs, a mission planner can efficiently task platforms for missions– Mission readiness can be quantified based on platform and equipment
availability– Selected platform data can be sent to operators and optimization
suites

• Platform Quality• Endurance• Flight Envelope• Fuel Capacity• Operating Height• Stealth Operating Height• Takeoff/Landing Procedure• Velocity
• Standard Cruising Velocity
• Maximum Safe Operating Velocity
• Sensor Quality• Range of Vision• Mode
• Image Processing• IR Processing• Video Processing
• Horizontal Rotation• Lens Zoom• Mount Placement• Vertical Rotation
• Radio Quality• Band Name (Frequency)
Extensions and Future Work
12
• Develop missions and tasks• Expand the ontology to include civilian domain platforms
– Add more detail to existing classes, more equipment properties
• Develop a tool to query feasible platforms for flight craft– SPARQL queries linking the ontology to a user interface
