[QUOTE="Andre Levite, post: 82539, member: 10850"] The Spark:s altitude is primarily calculated by an on-board barometer. There are two types of downward facing sensors: a camera to record the precise takeoff spot for RTH and ultrasonic sensors to detect the ground at low altitudes. I suspect your issue is related to reflections from the snow hitting the US sensors. We don't have snow here in Florida but I get often get aberant sensor readings due to reflections when flying over completely still water. It would certainly be easy to test this theory by flying over ground that is free of snow. I hope you can find some! [/QUOTE]
