Mission-Based Approach
• Needed 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– Sampling of missions to generate discussion only– Warning: these missions are not designed to meet specifically
derived scientific objectives• System engineering approach not used in defining these missions• Lack of specific information may make task seem unconstrained
– 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!
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
Hurricane Genesis, Evolution and Landfall
• Science objective: Observation of hurricanes to improve predictions of hurricane paths and landfall.
• Remote, high altitude measurements:
• Tropospheric measurements:
• Boundary Layer:
- Precipitation- Clouds- Meteorological sounding
- Electrical activity- Microphysics- Dust
- 4-D thermodynamics
- Winds
- Sea surface temperature
- Surface winds
- Surface imaging
- Turbulent flux
- Surface state: wave spectra, sea spume, etc
Hurricane Genesis, Evolution and Landfall
• High altitude, Mother Ship UAV: Very Long Endurance Platform
• Tropospheric UAV: Daughter Platform
• Boundary layer UAV: Small Platform
- Optical Imager: lightning
- Meteorological sonde
- Daughter ships
- Radar: cloud and precipitation
- Microphysics (typical of drop-sondes, thermodynamics)
- GPS reflectance: surface wave spectra
- Lidar: surface wave spectra
- Sounder: water vapor and temperature
- Radiometer: cloud and precipitation
- Infrared pyrometer: SST
- Winds
- Optical imager: surface imaging
- Meteorological sonde: in-situ
- XRBT thermocline
- Turbulence flux
