LG290P GNSS: Configuring RTCM Output at High-Rate

IoT Modules GNSS Module

I have an LG290P GNSS module and would like to record observation data at 20 Hz. How can I achieve this?

Not sure, see timestamp limitation (I can count 140 messages in 1000ms)…
there are too many and too long & big messages for spit_out but can see the 20 messages for rtcm only.
$PQTMRESTOREPAR*13
PQTMGNSSSTOP*09
$PQTMCFGFIXRATE,W,50*5D #set fix rate at 20Hz for all uart
$PQTMCFGPROT,W,1,1,00000005,00000004*39 #set output only rtcm on uart1

$PQTMCFGPROT,W,1,1,00000007,00000007*38 is the default for v6 beta version!
enable rtcm msm7 on current port:
$PQTMCFGRTCM,W,7,0,15,07,06,2,1*04
choose the ephemerid and rtcm U need
$PQTMCFGMSGRATE,W,RTCM3-1005,0*58 #disable fix position
$PQTMCFGMSGRATE,W,RTCM3-1033,0*5D #disable station info

$PQTMCFGMSGRATE,W,RTCM3-1019,1*54
$PQTMCFGMSGRATE,W,RTCM3-1020,1*5E
$PQTMCFGMSGRATE,W,RTCM3-1041,1*59
$PQTMCFGMSGRATE,W,RTCM3-1042,1*5A
$PQTMCFGMSGRATE,W,RTCM3-1044,1*5C
$PQTMCFGMSGRATE,W,RTCM3-1046,1*5E

$PQTMCFGMSGRATE,W,RTCM3-107X,1,0*2F      
$PQTMCFGMSGRATE,W,RTCM3-108X,1,0*20         
$PQTMCFGMSGRATE,W,RTCM3-109X,1,0*21
$PQTMCFGMSGRATE,W,RTCM3-111X,1,0*28         
$PQTMCFGMSGRATE,W,RTCM3-112X,1,0*2B         
$PQTMCFGMSGRATE,W,RTCM3-113X,1,0*2A

It worked well. I was able to record RTCM data at 20 Hz. Thank you.
