Configuration Files

Our Starter Kits which contain a base, a rover or a heading unit, are shipped pre-configured to make your life more plug and play.

Our standalone boards are shipped with the default ZED-F9P configuration.

If you “revert to default” a simpleRTK2B board, note that it will revert to the u-blox ZED-F9P default, not to the ArduSimple default. For getting back to the ArduSimple default you will have to upload the configuration files in this page.

 

Firmware version check:

The first step is to check that you have the latest firmware version on your boards. As any new technology, new firmware with improvements are released on a regular basis, and it’s common that the hardware you just received doesn’t have the latest version.

Have a look at this tutorial to check your firmware version and update if necessary. Or if you prefer, this videotutorial for firmware upgrade.

 

Loading a configuration file:

Download the Windows tool u-center (careful, not u-center 2 which is not yet compatible with ZED-F9P): https://www.u-blox.com/en/product/u-center
  • Go to Menu Bar > Tools >  “Receiver Configuration” (“GNSS Configuration…” in older u-center versions)
  • Select Generation “u-blox Generation 9”
  • Select the configuration file from your hard disk
  • Click “Transfer file -> GNSS”
 
When finished, the simpleRTK2B will start using the new configuration immediately. But if you remove the power, it will revert back to the previous one. To store permanently our new configuration, we need to:
  • Go to Menu Bar > View > Message View
  • Find the message UBX-CFG-CFG
  • Select “Save Current Configuration”
  • Click “Send”
 
NOTE for simpleRTK2Blite users: when loading configuration files to simpleRTK2Blite board, you are using UART1 (via USB with a UART-to-USB converter). The configuration files might change the baudrate you have on your board, leading to a loss of communication in the middle of the configuration file update. When this happens, just change the baudrate of u-center and load again the configuration file at the new baudrate.

ConfigurationFW 1.30FW 1.13Details
Base File File Starting from a default ZED-F9P configuration:

Enable survey-in with target accuracy 2.5m (should take no more than 5-10min)
Change UART2 baudrate to 115kbps. This improves the buffer use of the radio links.
Activate following RTCM messages
1005: Stationary RTK reference station ARP
1074: GPS MSM4
1084: GLONASS MSM4
1094: GALILEO MSM4
1230: GLONASS code-phase
We have selected this combination of messages because it's a good tradeoff between performance and required data link:

Performance can be improved by using MSM7 messages
RF Bandwidth can be improved by eliminated more constellations (e.g. remove Galileo), or increase 1005 to only be sent once every 5 seconds.
Rover 1Hz File File Starting from a default ZED-F9P configuration:

Change UART2 baudrate to 115kbps. This improves the buffer use of the radio links.
