Ok, so I was able to use the NTRIP server feed function of QGNSS to send RTCM3 corrections to a public caster server (caster.centipede.fr) and then use NTRIP from that caster to my rover and achieve RTK fix. The accuracy was equivalent to the commercial NTRIP server that I normally use, which is good.
For those trying to do the same thing, this is all I did:
-
Reset to factory with:
$PQTMRESTOREPAR*13 -
Set to Base station mode with:
$PQTMCFGRCVRMODE,W,2*29 -
Set survey-in mode to fixed mode and antenna location with:
$PQTMCFGSVIN,W,2,0,0,<ECEF_X>,<ECEF_Y>,<ECEF_Z>cksum
I have accurate location of my antenna, so I used fixed mode. -
Save configuration with $PQTMSAVEPAR*5A and reboot
So, while this appears to work ok, I would still ike to use the local caster if possible. The option appears to be there in QGNSS but the setup doesn’t seem to be fully implemented.
