RTK correction for a robot

Robotics
1

Hi

Im working on a robot prototype that will require precise positioning in large open areas. To achieve this I will require RTK correction base station (unfortunately I cant use available services) and transmit RTK corrections to the rover using LORAWAN.

For Base station Im thinking about SparkFun GPS-RTK-SMA Breakout - ZED-F9P, as I understand its a suitable one for the job.

For Rover I was hoping to use something a bit cheaper SparkFun GPS Breakout - ZOE-M8Q, as Ill probably end up having multiple devices on the field at some point.

question is - can ZOE-M8Q receive correction data? can I use it for the rover to achieve that magical RTK 1-2cm precision?

if ZOE-M8Q is not suitable for this task, what are alternatives that I can use?

Thank you

You need a receiver capable of processing RTCM correction data, and those are still pretty expensive.

Thank you for your reply

then Ill use SparkFun GPS-RTK-SMA Breakout - ZED-F9P (Qwiic) for rover and base
