Outdoor RTK

The RTK system consists on an onboard and onground equipment: the ublox NEO-M8P.
This chip is provided by Drotek in two boards : Tiny M8P and XL M8P.
Each board can play the rover station or the stationary station.
The boards can also be mixed.
However, the XL M8P is equipped with a LIS3MDL magnetometer which provides an external magnetic sensor to improve onboard heading.
