I’m very excited to test those modules LC29H DA and BS in order to make a rover - base configuration.
The boards with the modules are on their way, I need RTK in order to calculate some parameters like heading and position with the least amount of error posible.
But I find confusing how exactly do it, I wonder if someone in Quectel can provide the steps with commands needed to set up a Base sending RTCM messages for correction and all needed parameters to the rover via UART.
For example:
For Base
Step 1: $PAIR432,1*22
Step 2:
Step 3…and so on.
For Rover:
Step 1:
Step 2… and so on.
Also any documentation in their latest version as well as latest firmware will be much appreciated.
Hope you can help me with such request.
If any quectel forum user has also done it, will be great if you are willing to share.
I will send you LC29H(BS) EVB User Guide doc. We make some demonstration in this document. Hope it will help your debugging. And I will send you latest firmware via message.
I have similar project in progress like JMX’s. Yesterday I dug little deeper with LC29H(DA) and found out NMEA gives only 0.1 meter accuracy in NMEA GGA messages. Updated firmwares for LC29H(DA) and LC29H(BS) are much welcomed for me, where precision level is more precise and selectable, like earlier has been.
Also I had the chance to play with the modules, so far the RTCM corrections are being sent over TCP/IP by the BS and received using the NTRIP client on QGNSS and I got similar results but I have not tested extensively.
Seems like I cant get heading directly from the modules which is a shame.
Next step will be to do all at once without QGNSS and under Linux but that might take a while.
Could I also get the user guide. The firmware is: $PQTMVERNO,LC29HBSNR11A01S,2023/02/13,10:14:06*27
Any idea why even after 24 hours on in-site survey, the 3D positioning error is still >4 meters? The antenna is positioned on the roof with a full 360 degree view of the sky with no obstructions.
Tenho módulo LC29H(DA), gostaria que os senhores me enviasse o Firmwares atualizados para LC29H(DA) será bem-vindos para mim. Também gostaria que me enviasse o passo a passo para baixa, instalar e manusear o programa.
Hi! Im trying to convert RTCM from 29HBS to rinex for PPP but always obtain data that contains GPS L1 data only. But I cant figure out what the problem with output. It seems like RTCM output need to be configured or something… Please send me guide on LC29HBSN and latest firmware too. Thanks!
LC29H(BS) is a dual-band base station module. It’s default constellation mask is GPS+GLONASS+Galileo+BDS+QZSS. Currently LC29H(BS) doesn’t support change constellation mask. Please check your antenna if it supports the parameter below:
I do not know anything about that specific board. We have purchased the modules and made our own PCBs.
We are using public RTKBase. From the documentation, I see you need to use the module LC29H(BS). You will probably need to fix the coordinates for the RTK base module but I cannot help there for now
Do you mean that LC29HDA doesn’t output valid position when it’s moving?
If so, how is the performance in static senario?
Could LC29HDA get RTK fix with correction data injected?
