We have designed a system based on isoblue. Below you can find the pictures. Feel free to comment for improvements / changes. We did the holes for the side panels manually
but will upload the design files when we prepare them for CNC operation
We have also placed a U-Blox based RTK module inside so there are 3 SMA antenna connectors.
1 x gps
1 x gsm
1 x uhf (rtk related)
The sad thing is we are still trying to find some actual combines / tractors to test the system. Until now we were only able to feed the design with data from the isoblue public data section.
