Design and Field Campaign Validation of a Multirotor UAV and Optical Particle Counter

Autor: Chris Stopford, Konstantinos-Matthaios Doulgeris, Robert Mackenzie, Charles Chemel, Joseph Girdwood, Helen Smith, David A. Campbell, David Brus, Warren Stanley, Zbigniew Ulanowski

Small unmanned aircraft (SUA) have the potential to be used as platforms for the measurement of atmospheric particulates. The use of an SUA platform for these measurements provides benefits such as high manoeuvrability, re-usability, and low-cost whe
