Base Station Address on Local Network
At the end of the installation, RtkBase will display the IP addresses of Raspberry pi on the screen. However, there is another way for modern operating systems — the address rtkbase.local, which means the site can be opened as http://rtkbase.local.
Please note — you must type the full address as http://rtkbase.local. If you accidentally enter http://rtkbase.local, or just rtkbase.local, your browser may automatically attempt to use HTTPS. This will not work, because the base station only supports HTTP (not HTTPS). The HTTP protocol uses port 80, while HTTPS uses port 443 — and this port is not currently active on the device.
Unfortunately, this method only works inside your local network. That means if you're trying to access the base station from your phone, you’ll need to connect to the same Wi-Fi network and (ideally) disable mobile data to ensure the browser stays on the local connection. Otherwise, your phone simply won’t have access to the local network.
For ELT0731 and ELT0733 stations, there is an additional limitation: these stations will not operate correctly in the 192.168.3.* subnet, because the internal address of the Septentrio Mosaic receiver is 192.168.3.1.
Search via Windows Application
Starting from version 1.9.8, the easiest way to locate your base station is to launch the find_rtkbase.exe application. You can find this application on the SD card or download it from our GitHub repository via the provided link. Launch the application.
Click the Find button.
Once the search is complete, you’ll see links and IP addresses that you can use to access your stations:
Changing the Password
Log in to the site for the first time (using http://rtkbase.local as the address).
Enter the password “Admin”.
Click on Settings at the top.
At the bottom, in the “System Settings” section, find “Change Password” and enter the new password.
Click on the “Change Password” button and see the message on the screen. Now click on the “Log Out” button and log out.
You will end up on the login screen again. Enter the new password and check the “remember me” box.
You will be taken to the Status page.
Shutdown
You can turn off the device by disconnecting the power. However, the most gentle method is to press the “Shutdown” button in the web interface.
