What considerations need to be made to fly in the snow and during cold weather
Operating Temperature Range
The operating conditions for the R2A is -20 to 65 degrees Celsius (-4 to 149 degrees Fahrenheit). Outside this temperature range and the unit will not operate properly so make sure you're flying in environments within this temperature window.
Cold Weather Considerations
As with all battery operated devices, cold weather is not a friend. Cold weather will drastically reduce flight times and in some cases prevent batteries from being used. If you're flying in cold weather locations be sure you have a way to keep your batteries warm before flight and during/after charging. Plan for a lot more flights with shorter times so have ample batteries to feed your drone. You may be used to flying 100 acres in a single swap but with frigid conditions your coverage and flight times will see a dip.
How Does LiDAR Handle Snow
We've taken the R2A to a glacier in Alaska and it did great. Since LiDAR relies on reflectivity (and snow is very reflective) there was no issue with collecting data. HOWEVER, you won't be getting the ground contours, you will be getting the contours of the snow above the ground since the laser pulses don't penetrate solid surfaces.
Again, if you fly over snow you will NOT be getting ground contours. You will be getting snow top contours.
