The question really speaks for itself. I don't have any way to connect with my navio2, running ardupilot, during flight (except a radio controller if things go wrong). Could I still make my drone autonomously follow a certain path, take pictures, etc. ?
but you need to be careful to specific parameters in Ardupilot, so as not to terminate the flight inadvertently when you loss connections (caution only do this if you have a very specific reason for doing so, it can be dangerous to continue because you may loose control of your drone, i did NOT test these settings):
For explainations for the parameters refere to here:
I'am not liable about any damage you may cause by doing so!
