First of all: Big up Bernt for your effort!
I slowly getting into the game of UAVs for mapping and surveying. I'm a PhD Student using remote sensing to assess forests. Within the next year I want to complete my own platform to carry sensors. I currently have a Navio2 on a Raspi3 and I use the second generation Raspi cam for video streaming. So far I'm using my home router to set everything up and test things on. Soon I want to plant the autopilot on a F450 quad to do the first gentle test flights. Once everything works the way I want it to I plan to use a Bormatec Maja fixed wing platform. Using 4G for telemetry and streaming video sounds like a really great and future proof solution. However since I am planning to use the UAV in different countries I think maybe WiFi is easier to handle. Hence I would like to ask:
What kind of WiFi router/system would you suggest that I can somehow power out in the field?
Also what kind of range can be achieved with a high gain router? Is it neccesary to build an antenna stand that automatically points to the rover or is a static station good enough? I'm very inexperienced concerning any signal transmission..I want to achieve a range that enables me to cover a mapping area of roughly 2km² and while the GCS may be outside the forest I will typically be flying above forest. I hope you can lead me in the right direction 🙂
