Quectel LG290P
Configuration
Base
The LG290P is put into base station mode with a few commands and reboots. The unit can self-survey or known ECEF coordinates can be provided.
| Command | Description |
|---|---|
$PQTMRESTOREPAR*13 | (Optional) Set unit to defaults |
$PQTMSRR*4B | Reboot |
$PQTMCFGRCVRMODE,W,2*29 | Enter base station mode |
$PQTMSAVEPAR*5A | Save parameters |
$PQTMSRR*4B | Reboot |
$PQTMCFGSVIN,W,2,3600,1.2,163333.3333,-4224444.4444,4465555.5555*3F | Enter survey-in mode with a known location |
$PQTMCFGSVIN,W,1,1800,1.0,0,0,0*03 | Enter self survey mode for 3600 seconds with a 3D accuracy limit of 1 meter. |
$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,1*45 | Enable survey status messages PQTMSVINSTATUS,1,#######,2,…… is reports a good survey. |
$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0*44 | Disable survey status messages |
$PQTMCFGRTCM,W,7,0,15,07,06,2,600*03 | Configure RTCM MSM7, set 15° elevation mask, send ephemeris data every 10 minutes. |
$PQTMCFGMSGRATE,W,RTCM3-1019,1*54 | Enable GPS ephemerides RTCM messages |
$PQTMCFGMSGRATE,W,RTCM3-1020,1*5E | Enable GLONASS ephemerides RTCM messages |
$PQTMCFGMSGRATE,W,RTCM3-1042,1*5A | Enable BeiDou SV ephemeris data (one message per SV) |
$PQTMCFGMSGRATE,W,RTCM3-1046,1*5E | Enable Galileo I/NAV SV ephemeris data (one message per SV) |
$PQTMCFGMSGRATE,W,GGA,1* | (Optional) Enable NMEA GGA messages - useful for timestamping the log |
$PQTMCFGMSGRATE,W,ZDA,1*14 | (Optional) Enable NMEA ZDA messages - useful for datestamping the log |
$PQTMSAVEPAR*5A | Save parameters |
$PQTMSRR*4B | Reboot |
Rover
The default configuration of the LG290P is to operate in rover mode. The easiest way to enter this mode is to reset the unit to defaults.
$PQTMRESTOREPAR*13 $PQTMSRR*4B
The resulting sentences are sent at 10Hz and are quite dense, a baud rate of 460800 is recommended. If 10Hz data is not required (or the bandwidth is too great) the sentences can be slowed down using the $PQTMCFGMSGRATE command. GSA1) and GSV2) are by far the longest and consume the most bandwidth. If you want a 10Hz location stream, but don't need GSA/GSV at that rate, they can be individually slowed to 1Hz:
$PQTMCFGMSGRATE,W,GSA,1* $PQTMCFGMSGRATE,W,GSV,1*
