RTK/GPS Inject Using NMEA 3rd Party Base Station

Hi,

I am looking at the possibility of using a 3rd Party Base Station to deliver correction messages via COM Ports.
I am using a Trimble R8-3 as the Base. I have configured it to output the NMEA GGA String and it is being read by Mission Planner. My main question is if this will in turn work and if so, what other Strings do I need to output from NMEA to create a full set of Strings that Mission Planner will use?

Thanks in advance,

Scott

NMEA is not the protocol you require. the base must output rtcm, and the gps on the drone must also support rtk and rtcm input
