  1. 1. Aurora-Imaging UAV Cameras

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Benjamin Girchman; Joel Widén; [2023]
    Keywords : ;

    Abstract : Ground based optical observations are limited by weather. One of the possible solutions is using adrone to fly above the clouds. This enables new approaches when planning experiments. The aim ofthis project is to produce and evaluate prototypes of aurora-imaging cameras that will be placed insideof such a drone. READ MORE
