FIXAR has been developed and tested to perform in extreme weather conditions between -30 and +60 ℃ (-22 °F to 140 °F), and up to 4 500 m (14 763 ft) above sea level (on Elbrus mountain). Since a magnetometric sensor isn’t used, FIXAR UAVs are fully protected from strong electromagnetic fields (resulting from the proximity to high-voltage power lines, radio or mobile phone base stations, big metal objects, etc.).
