UAV Technological Timeline
Unmanned Laser Scanningwww.rieglusa.com
• 1980’s – RPV (Remotely Piloted Vehicle)
• Operator on ground, almost near real-time control of aircraft on
variable surfaces
• 1990’s – UAV (Unmanned Aerial Vehicle)
• Operator on ground and can take over intermittently as necessary for
course correction, introduction to complete automation
• 2005+ - UAS (Unmanned Aerial Systems)
• Operator on ground to modify or take over in emergencies, complete
flight path automation

UAV’s – Effective New Tool Changing the Landscape
of Aerial Surveying and Data Acquisition
Unmanned Laser Scanningwww.rieglusa.com
• UAS will never replace fully piloted aircraft.
• UAS size = small = decreased radar, acoustical, infrared and environmental
signatures
• UAS is cost effective, as compared to fully manned aircraft (cheaper fuel
costs, no crew downtime, minimal aircraft maintenance, no aircrew, minimal
weight, easy mobility)
• Safety is improved due to both piloted and autonomous flight.

Advantages of each type of UAV’s
Unmanned Laser Scanningwww.rieglusa.com
Fixed Wing Helicopter UAV
• Highly maneuverable
• Great placement of sensor
payload
• Single motor operation
• Vertical take off
• Hovering in place
• Low altitude flight
• No need for a runway
• Ability to stay airborne is not
a function of the drive motor
• Less overall power
consumption per flight.
• Stable in flight
• Robust
• Can survey farther distances
• Good payload capability
• Single motor operation
Multi-Rotors
• Complexity of system design
has increased and developed
over recent years.
• Lighter and stronger materials
and components
• Multi-rotor components readily
available
• No need for a runway
• Vertical take off
• Hovering in place
• Low altitude flight

Benefits to LiDAR Integrated UAV’s
Unmanned Laser Scanningwww.rieglusa.com
- New technology allows for LiDAR acquisition at a fraction of the current aerial
surveying aircraft costs.
- Small form factor allows for easy mobilization to site and thus, more remote
sites.
- Easy mobilization and lower operational costs, as well as time saved, results in
a faster return on investment for the LiDAR/UAV remote sensing.
- Faster deployment for repeat scans of an AOI
- Expands LiDAR to new and novel applications currently in use with UAV’s.

Conclusion
Unmanned Laser Scanningwww.rieglusa.com
RIEGL Laser Measurement Systems’ latest developments, the RiCopter
and the VUX-SYS, are the first systems in the ULS segment that are
bridging the gap between airborne, mobile, and terrestrial laser scanning.
ULS systems are bringing professional survey-grade quality of laser
scanning that will enable current and new users to be highly productive
and to deliver 3D analytics much more efficiently.
