The potential of HALE-UAV for disaster management

• Nicolas Lewyckyj
• ISCRAM 2004 - Brussels

2
Current situation for disaster management imagery

• Satellite Data
• - cheap
• - databases exist
• - if available short turnaround times
• - not always available
• - bad X,Y,Z precision
• - relatively low resolution

• Aerial Data
• - high resolution
• - good position precision
• expensive
• long delay periods
• - different providers each with own quality

3
Which information do we need in case of disaster
or crisis situation ?

• Large area coverage specific missions
  database for comparison gt Aerodynamic platform
• Different sensors (meteorological conditions and
  applications)
• gt Large payload or small light sensors
• Information during long periods gt very long
  endurance gt solar energy
• Air traffic security clearance problems gt
  high altitude (gt 14 km) en preferably
  lightweight
• Real-time data
• gt direct transmission to ground stations
• High Altitude Long Endurance (HALE)
  Solar UAV !!!

Unmanned Aerial Vehicles (UAV) can be used for
dangerous, dull dirty jobs

• Goal serve as platform for instruments
• Applications military, humanitarian, scientific,
  
• Different sizes (cm gt 200 m)
• Different systems (ballon, airplane, flying wing,
  )
• Different altitudes (m gt 29.5 km)
• Different time intervals (minutes gt months
  expected)

HALE-UAV the missing link
Geostationary satellites
35400 km
Polar orbiting satellites
600-800 km
Observation altitudes
14-30 km
Stratospheric platforms, HALE-UAV
0.1-5 km
Airborne sensors, UAV
Groundlevel

HALE-UAV combines the best of satellite and
aerial data

• - cheaper unmanned, automated operation
• - high resolution 20 cm resolution
• - high accuracy 10 cm height accuracy
• - direct use data and applications available
• - short turnaround times available from library
• - single provider known quality from database
• - public politic acceptance

Synergy of sensors provides 24 hours survey
capability

• Multispectral digital camera ( 20 cm pixel
  resolution)
• Vegetation monitoring, environmental
  pollution,
• InfraRed camera (1 2 m pixel resolution)
  Forest fires, avalanches, embankment survey,
  security .
• Laser scanner
• Earthquakes, inundations,
• Small radar (SAR)
• mobility (evacuations), oil spills,
• (Air quality measurements and small camera cloud
  detection)
