How to cast RTK/RTCM data over wifi to drone?

Hi all, I wish to broadcast RTK messages from mission planner to multiple drones over a common wifi network. I have raspberry-pi running on all the drones and all connected to the same local wifi network. Is there a way I can achieve this?? I am using Mission Planner auto-config of Holybro RTK systems (based on u-blox)

Mission planner already supports broadcasting both local and NTRIP sourced RTCM data to all MavLink links.

how do I achieve that?

You need a fixed base GPS or a connection to an NTRIP server.
