this is our latest compilation documenting flying civilian UAV during the wintertime.
Key acheivement was extending flight endurance up to 2h WITH camera and parachute onboard, as in snowy conditions you typically can fly only once every few hours. The snow gets into all photo equipment even through the smallest mounting hole, therefore no simple camera cover is enough. You have to fly once and then clean up, charge and de-fog the camera. Flight time and necessity of keeping light weight of the UAV becomes the limiting factor.
Landings are often on frozen, hard soil.
The snow slowly melts to water and flows all around the fuselage, in places usually not accesible by rainfall.
You can change a mission without connecting a laptop - a huge bonus on a frozen field.
Therefore, fly with confidence using Pteryx.
