Yeah we are creating a autonomous rover which we use a moving baseline to calculate yaw. Since our base is metal we it made more sense to use 2 GPS’s without any compasses.
The ESP is getting corrections from our stationary base, feeding it to the first ZED. And then that ZED is feeding its moving corrections to the other one.
We were mostly interested in ALC just to combine them into 1 board which would reduce wires needed and it would have a smaller form factor.
