  1. Workshop Overview April 26-28, 2005 Tim Cox, NASA DFRC

  2. Outline • Background • Objectives • Approach • Missions

  3. Civil UAV Capabilities Assessment • Need: identify capabilities needed in future civil UAV’s to enable informed funding decisions on key technologies • Task: Develop a Civil UAV Capability Assessment (2015 Time Frame) • Customers: Sub-Orbital Science Program (Yuhas), Vehicle Systems Program (Camacho) • Complement DOD roadmap • Homeland Security, Commercial, Land Management, Earth Science considered • Objectives : • Document future missions of civil UAVs based on user defined needs • Document the technologies necessary to support those missions • Discuss SOA of those technologies, identifying those in progress, those planned, and those for which no current plans exist • Provide the foundations for development of a comprehensive civil UAV roadmap • Status: • Initial version is available via web-site • Information sources for initial version • primarily earth science missions • personal interviews: U.S. Coast Guard, U. S. Forest Service, Idaho Department of Fish and Game, University of Hawaii Dept. of Oceanography

  4. Summary of Findings • 35 Missions • Earth Sciences • Firefighting Missions • Wildlife Management • Capabilities and Technologies • 21 Basic Technologies and Capabilities • Cross-referenced to Mission Support • Economic Benefits • Non-recurring costs • Recurring costs

  6. SSMF Workshop • Major source of information in Assessment: Suborbital Science Missions of the Future (SSMF) workshop • Pre-preliminary design exercise by sub-orbitial science community to develop innovative mission concepts that take advantage of UAV’s • 20+ conceptualized missions • Provide a basis for identifying future UAV capabilities or technologies • From SSMF information: • Parallel developments necessary for science sensors to enable UAV mission vision • Power and propulsion technology one of the key enabling technologies (e.g. long endurance)

  7. Purpose of the Workshop • Reveal science sensor technology gap data • More details than just miniaturization • Assessment to include a section on this topic, ESTO authored or edited • Determine power and propulsion technology shortfall data • Data intended to supplement platform technology gap section in assessment

  8. Workshop Approach Mission sessions Tech sessions

  9. Mission-Based Approach • Need a context for sensors, power and propulsion to use for examining future capabilities • Aid to answering question: where are the technology gaps? • Make use of previously developed conceptualized missions (SSMF workshop), developed by science community, to provide the context • Sample of missions based on sensor variety, propulsion issues • Missions are pre-design phase, highly conceptual • Useful for determining where technology needs are • Useful as a tool in an exercise which reveals technology gaps • Not designed as a flow down from specifically derived scientific objectives • Assumptions and inferences on sensors and power and propulsion attendees will be required • This is OK!!! Just document assumptions and inferences • Keep the discussion flowing!

  10. Mission Characteristics • Six Mission descriptions provided: • Hurricane Genesis, Evolution, and Landfall • Cloud, Aerosol, Water Vapor, and Total Water Measurements • Active Fire, Emissions, and Plume Assessment • Southern Ocean Carbon Cycle • Antarctic Explorer (Cyrosphere) • Vegetation Structure, Composition, and Canopy Chemistry • Potential platform class(es) to assign to a mission • Daughter ship UAV (launched from mother ship) • Small UAV (~20 lbs payload) • Medium UAV • Large UAV (~2000 lbs payload) • Very Long Endurance UAV (3 days +) • Assumptions across all missions • For sensor track: Platform is capable of performing the mission as described in the profile • OTH network centric communications • ‘File and fly’ access to airspace • ‘Plug and Play’ open architecture • Capable of 100% nominal autonomous sensor operation
