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)
5
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
6
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
7
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)
