Hi @alexbrooy,
RTKBase use Rtklib to convert the raw signal from the Gnss receiver to Rtcm. It doesn’t use the F9P rtcm messages. So all messages supported with rtklib are available.
Is you serial input the correct one ? ttyAMA0, ttyACM or another one.
yes, first i had on the webportel: hidraw5 i have change that tot ttyAcm0
if i use code ./install.sh – detect-usb-gnss
he show me then /dev/ttyacm0 and then ublox story
i have the idea that the raspberry pi works.
but the f9p of ntrip not. i have now put the f9p on the computer en still not work
Hi there,
Thank you for the big help, i did totally not follow the step-by-step and did not connect the F9p before the first start of the Pi. Restarted the process and worked fine for me 
.
Now i have to move the whole set under the rooftop, so, in order to make it wright the first time, I would like to know what would be the steps for the radio install (as it wild be difficult to access later on) ! I already have radio from ardusimple, would it be better to just output it as it it done by ardusimple ? https://www.ardusimple.com/product/simplertk2b-starter-kit-lr-ip65/
Anyway, Thumbs up and big thank you for the great RTKBase

Hi!
The next release with Rtcm serial output (for radio) will be available in a few weeks (I hope). It will be possible to upgrade from the web interface.
The most important modifications are:
- Rtcm serial output (for radio link)
- Rtklib 2.4.3-b34

RTKBase 2.2.0 is out!
[2.2.0] - 2021-01-12
Comment
- 2.1.x to 2.2.0 upgrade could take up to 10 minutes. Please be patient.
- After the upgrade, restart your services or reboot the base station
Added
- New Rtcm serial service to send a rtcm stream on a serial output, like a radio module
- RTKBase release number, receiver model, and antenna information are sent on RTCM stream (message 1008 and 1033 added)
- GUI->Status: Button to copy realtime coordinates to the clipboard
- GUI->Settings: You can edit the antenna info in Main service options
- GUI->Settings: Spinners and countdown added on reboot modal window
- GUI->Settings: Auto refresh the webpage after a reboot (fixed time duration)
- The archive_and_clean script delete oldest archives if there is less than 500MB available.
- The install script check if there is enough space before starting
Changed
- Upgrade to RTKLib v2.4.3-b34
- Pystemd updated to 0.8.0
- Pystemd is now installed from Pypi
- Some python module updates
- More dependencies are installed for aarch64 platform
- The realtime base location calculation is now using dual-frequency ionosphere correction. You won’t see the location anymore if you use a single frequency receiver.
- Default value for archive rotation lowered to 60 days
Fixed
- Cleaning update modal box when closing it
- writing absolute path to python3 in rtkbase_web unit file
Security
- Cryptography module updated to 3.3.1
Warning for radio output:
If you plan to use a radio module on uart on a single board computer, don’t forget to enable this i/o. The methods to do this on a raspberry pi varies depending on the version but here is an example with a Pi 3B+.

Hi, Great job! Is it planned to make a ready to use ISO file ?
Like i did use for the first install : rtkbase/README.md at master · Stefal/rtkbase · GitHub
Yes it’s planned, but I can’t give you a date.
btw: If you want to update your already existing installation, you just have to click on ‘check update’ on the settings webpage.

Thank you very much, I updated my existing installation without any problems.

Hi, this is brilliant by the way! I have this working on NTRIP, however, I also need to be able to output RTCM3 to serial for a UHF radio. I’m running this on an RPi4 connected to a Seeed Studios RS-232 To TTL Converter (MAX3232IDR). I’ve amended /boot/cmdline.txt and /boot/config.txt and tried the lines `dtoverlay=pi3-miniuart-bt’ and ‘dtoverlay=disable-bt’ and i still have no serial output. is this a RPi-4 issue? I have a Pi-3 on the way. what uart to RS232 devices are people using?
Thanks.
Thanks!
I can’t give you some feedback for the Pi4, I just know that there are more uart available, so it “should” be easier than the Pi3.
Wouldn’t it be easier to use a USB to RS232 converter? Even the cheap Chinese Prolific clones work on a Raspberry, those that are banned by Windows.
Could use a 3.3v serial to RS232 converter. Ideally it would be DTE (male pins), just like a normal computer serial port, or what you’d get with the USB converter. I’ve noticed these are kind of hard to find. It’s easier to find DCE versions, which has the female connector. That can work too, but you might need a gender changer and a null modem adapter to hook it to other serial devices. Also there are lots of 5v RS232 adapters, but not as many 3.3v ones.
So yeah it might be easier to use the USB serial adapter.
I’ve built the RASPI4 station as specified and am now trying to find its fixed position. I’ve downloaded the logfile a couple of times, convbin it to .obs, and submitted it to the Canadian CSRS-PPP service for processing. Sometimes it interprets the file as “static mode” and other times it interprets it as “kinematic mode”.
Does anyone have any idea of what I’m doing wrong? Is it safe to assume that RTKBase sends a configuration to the ZED-F9P prior to data recording or are we supposed to do that prior to launching RTKBase? Any pointers or suggestions are appreciated. Thank you!
Hi!
Yes, RTKBase sends a configuration to the F9P if it is connected/detected during the installation. If you see the sats levels on the status page, the configuration should be ok.
I sent a 24H rinex file to the canadian CSRS-PPP service (ubx to rinex conversion, with -tadj=1 option) and here is what I’ve received (first pdf page only):
Thx Stefal. I am getting a both types of documents back from the processed logs. The one you have shown and also this one I have attached. The difference appears to be in the “mode”. Static vs Kinematic.
There is something strange: the doc says “Single frequency”. Please check your ubx to rinex conversion parameters.
Will do. Thx for that suggestion.
Hi Stefal
I have a XLR simpleRTK2B-F9P V3 running radio corrections using xbee pro sx (ardusimple XLR starter Kit) but I have a few areas where the radio signal drops out.
Can RTKbase run along side the radio corrections?
Looking to use rtk2go for the few areas the radio doesn’t work (but cell does) and running radio corrections over the rest of the property as cell is limited.
Just to be clear he wants to use RTKBase to simply relay some RTCM messages picked up on serial to the NTRIP server. Kind of a subset of what RTKBase does.
