RTKBase - a tutorial

Afternoon all

My project to get a community network of base stations up and running is gathering some interest, so I thought I’d write a guide on how to set it all up. From “what do I buy”, to “message sets, wtaf?”

Interested in any and all feedback please!



Would it be possible to run this on a Pi Zero if using a uart connection to the GNSS receiver?

On the face of it, I would gamble with a pi zero, they’re cheap enough to make it worth a try. It also seems like you could use USB too. Note tho - the Pi Zero W includes wifi, if you need that. The zero has no ethernet or wifi that I can see.

Not seeing different OS builds for the zero and model 3/4 etc. Less powerful CPU, but plenty memory. I’d like to think it would be OK.

This sounds like an issue with the pi zero was squashed: RTKbase img for raspberry Pi Zero - GPSD issue · Issue #175 · Stefal/rtkbase · GitHub

So I’d say go for it - and let us know how you get on :wink:

The installation instructions should be largely the same, but if the pre-built image won’t boot, you could just use a standard Raspian image and follow the rtkbase manual installation instructions.

What configuration file is needed for F9P, for this base.

None! rtkbase will auto-configure it for you, that’s why it’s important to have it plugged in at first boot.


Thanks. F9P was connected when Raspberry started. Looked at the configuration of the module. How would all the settings correspond to the setting of the base. But here is Time Mode 3 0-disabled. Where can I read to check what the settings should be. Yes, module firmware 1.13. I didn’t update it. Just immediately connected a new module that was.

You could connect it back to u-center and check settings are in there OK? Once it’s ran through the config in rtkbase, it won’t run it again (unless you tell it to from the cmd line - as far as I know!). Why it wouldn’t be in Time Mode 3 tho, not sure - that’s odd. I’ve a spare one here I might try it with later to see how it is. Is it working as a base regardless however?

In the evening I’ll try to run it with Rtk2.go. Then I’ll let you know.

It works with rtk2.go. The snip contains the database data.

How can I change the router name and password in the settings? I opened the flash drive, and there is no wpa_supplicant.conf file where I wrote the data. I need to connect another router. How to do it. Or you have to reload the program for it to appear. Where can he be. I don’t want to redo the settings.

Connect over ethernet temporarily, and:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Thanks, I’ll try.

The wpa_supplicant.conf file is moved at first boot by the way, so it’ll no longer be available in the root for Windows. A Linux machine could mount the drive tho. There aren’t that many settings tho, it doesn’t take long to reflash entirely and start from scratch.

Thank you. I found information on how to do this via an Internet cable, it’s easier to reflash everything from scratch.
