@mr337 Thanks for helping me out here, I will try to do some shopping during the week and also order some spare parts. I am familiar with C and (more with) Python. Linux (cli-based) is also no problem at all as I use this for my daily job. The ROS-Navio2 IF upload would be really appreciated. Last night I installed the ardurover on the pi and connect it to my APM planner 2 -app on my Mac. I will keep you updated if there is some more progress.
other topic: I was just thinking if Reach (the complete RTK package) could be a good alternative to have RTK based precision for my final setup? I saw some pretty amazing precision tests here:
If I have some more time in the weekend I will try to show what kind of machine I meant earlier.
