i have got two gps rtk2 (zed-f9p) from sparkfun. i wanna use one as a rover and one as a base station. i am facing difficulities to configure base station. don,t know how to use survey-in-mode or use ntrip client to get rtcm correction data. and after that how to transfer it to rover using sparkfun bluetooth mate.
So perhaps SparkFun can talk you through the process? https://learn.sparkfun.com/tutorials/gps-rtk2-hookup-guide/all
SURVEY-IN started in uCenter, UBX-CFG-TMODE3 pane sets the parameters, UBX-NAV-SVIN reports the progress.
The uBlox C94-M8P and C099-F9P manuals and app notes might also cover salient material.
Plenty of forum posts too.
