Its a slow project :)

I found the NTRIP servers connection wasn't as steady as I would like, so opted for the local base station and rover option. I ordered another Ardusimple RTK2B module ($$$) and configured it as a base station. I'm using a pair of HC-12 modules to let the base station and rover communicate.

Its working, and gets a solid fix.

I'm now working on the code to make the rover navigate and move. This are functions to do things like.

Get compass reading.
Calculate direction to next way point.
Rotate until compass faces new direction.
Move forward, check wheel turns.
Following a line between old and new waypoints.
If off to one side, make little changes to one motor speed.
