LC29HDA in Base station mode sends both correct and incorrect 1005 antenna data

I am running an LC29HDA in base station mode with fixed coordinates.

I am setting the following values, then resetting the GPS:


$PQTMRESTOREPAR

$PQTMCFGSVIN,W,2,0,0,3585433.2651,-201861.6412,5253725.3335

$PQTMCFGRCVRMODE,W,2

$PQTMSAVEPAR

The base station then sends pairs of RTCM3 1005 messages - the first is the fixed values but the second is dynamic (incorrect) and changes each time:

{"class":"RTCM3","device":"stdin","type":1005,"length":19,"station_id":3335,"system":["GPS","GLONASS"],"refstation":false,"sro":true,"x":3585433.2651,"y":-201861.6412,"z":5253725.3335}
{"class":"RTCM3","device":"stdin","type":1005,"length":19,"station_id":3335,"system":["GPS","GLONASS","GALILEO"],"refstation":false,"sro":true,"x":3585431.2332,"y":-201859.9420,"z":5253722.1505}

I have tried disabling 1005 by doing:

$PAIR434,0

However this disables the ‘correct’ fixed one, but leaves the ‘incorrect’ dynamic one.

How do i make it only output the fixed value? Is there an updated firmware available?

Firmware info:

$PQTMVERNO,LC29HDANR11A03S_RSA,2024/03/19,13:55:31*20

Hi,try the correct sequence…

$PQTMRESTOREPAR*13
$PQTMCFGRCVRMODE,W,2*29
$PQTMSAVEPAR*5A
reboot or $PAIR023*3B
now the base_fix $PQTMCFGSVIN,W,2,0,0,3585433.2651,-201861.6412,5253725.3335*17
$PAIR605*39 or $PQTMCFGSVIN,R*26 for check if ecef base is correct
$PAIR434,1*24 ==> set RTCM3.x output with message type 1005
$PQTMSAVEPAR*5A
$PAIR023*3B

Thanks, but I see no difference with the commands in this order (I have tried a few others, like doing PAIR434 earlier as well, but they also don’t help).

I have now updated the firmware on this device to LC29HDANR11A05S_RSA

Having re-run the setup commands it now only sends a single 1005 message that corresponds to the coords added via PQTMCFGSVIN

Not sure if the fix came from an update in the firmware, or if doing so reset the device such that it resolved the issue, but going to mark this as the solution.
