Question about LG290P RTK Breakout Base Station Build

[PaulZC]

Hi John (@JohnEH ),

I am sure other folks will chip in here later today. But, to get you started:

Yes, you can use QGNSS or PyGPSClient to fully configure the LG290P. Personally, I like PyGPSClient because that makes it easy to build up scripts of commands to configure the GNSS. Also, it runs well on RPi…

You are going to need to get to know the Protocol Specification. To put the GNSS into Base mode, you need PQTMCFGRCVRMODE,W,2 ( $PQTMCFGRCVRMODE,W,2*29\r\n ). PQTMCFGSVIN can be used to set survey-in mode or fixed mode with ECEF coordinates.

If you search for PQTMCFGRCVRMODE here, you will find gems like the post linked below.

I hope this helps,
Paul

Sparkfun lg290p Survey-In Setup

I am attempting to set up my sparkfun Lg290p breakout board as a locally hosted base station which I then would use to send all of my rovers the RTCM data corrections to get the RTK lock for each rover. The problem im running into at the moment is attempting to find the exact location of my base station. I need to be able to utilize the “Survey-In” mode of the quatcel chip so that I can run the survey for a couple hours to get the exact gps location of the antenna for the base station. When attempting to put my board into base station mode, (and then eventually in survey-in mode) I run into the issue where the serial port just starts spitting out gibberish (maybe binary?) immediately after putting the unit in base station mode and then saving and rebooting. I factory reset it with: Sent: $PQTMRESTOREPAR13 Received: $PQTMRESTOREPAR,OK3B Then I wanted to set it to base station mode: Sent: $PQTMCFGRCVRMODE,W,229 Received: $PQTMCFGRCVRMODE,OK64 Then upon save and reboot this is wh…
