Leica Geosystems UAS Airborne Sensors MAPPS Summer Conference July 2014 Alistair Stuart 1
Sensors for UAS! Promise of UAS is to expand aerial data acquisition capabilities for traditional and non-traditional applications Larger UAS can carry standard versions of existing large- or medium-format airborne sensors. Small UAS are relatively affordable and will appeal to a larger group of users across diverse application areas. Both imaging and non-imaging sensors will be deployed on small UAS platforms 2
