RTKBase: a GUI for your own Gnss Base Station

GPS / RTK / GNSS
61

After looking for a little more information and generating the position of the base with the rinex file, I was able to obtain an RTK correction via TCP in less than 1 minute and it is super stable.
The only current concern is that the raspy is inside a sealed box, a very hot day it can have a high temperature and fail, is there a way to measure the temperature or is it not relevant? I only have passive heatsinks on the raspy.
Thank you very much.

62

maybe an heat pipe going outside the box ?

hello. In the github repo I see that you have mentioned 1005, 1012, etc. msgs in setup page. Does your software add these messages ?

64

Don’t both those message types come directly from the F9P?

65

Sorry, 1005 - yes, it generates. But 1012, 1006 does not. So I wonder, if it adds by itself

66

dear Stefan
I have installed the raspberry pi without any problems. I can also login to the raspberry pi via webportel. the problem I do have is that the status page is not receiving anything. and sent. in my opinion I have set the ntrip well. what am I doing wrong or have I forgotten.

67

Hi. I have installed RTKbase on my pi4 following the easy way, flashing the image on as card.
When I plug the f9p, the pi4 does not start up. I can not access the webpage.
I can access to webpage only if I have f9p unplugged

69

I have solved my problem, not enough power for my raspberry!
Works now

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.

71

Is you serial input the correct one ? ttyAMA0, ttyACM or another one.

72

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

73

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 :slightly_smiling_face:.

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 :star_struck: :star_struck:

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

77

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.

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.

81

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.
