Hi Vasi, read here: https://www.waveshare.com/wiki/LC29H(XX)_GPS/RTK_HAT#RTK_Base
You have done the Survey-In observation but for a good position need at least 24h = 86400s …however did
$PQTMCFGSVIN,W,1,3600,15,0,0,0*15
then
$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,1,1*58 but before apply
$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0,1*59 note the ecef value and then appy for close…
see also $PQTMCFGSVIN,R*26 before close, that indicate the last value if all done 86400…
now close ($PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0,1*59) then apply
$PQTMSAVEPAR*5A
reboot PAIR023*3B
set fixed base in ecef e.g.
$PQTMCFGSVIN,W,2,0,0,4013185.2205, 1748875.1673,4623656.6043*24
continue with rtklib “strsvr” …
