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.
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.
Loading a configuration file:
- 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 GNSS -> File”
- Go to Menu Bar > View > Message View
- Find the message UBX-CFG-CFG
- Select “Save Current Configuration”
- Click “Send”
Configuration files:
Filename simpleRTK2B_FW113_Base-00.txt
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.
Filename simpleRTK2B_FW113_Rover_1Hz-00.txt
Starting from a default ZED-F9P configuration:
- Change UART2 baudrate to 115kbps. This improves the buffer use of the radio links.
- Disable SBAS, to avoid position jumps during short RTK corrections interruptions.
- Disable Beidou, to make it simpler to increase navigation rate to 10Hz without troubles.
Filename simpleRTK2B_FW113_Rover_sends_GGA_to_base_1Hz-00.txt
Same as Rover plus:
- Disable all NMEA messages except GGA on UART2.
- Enable NMEA output on UART2.
Filename simpleRTK2B_FW113_HeadingKit_MovingBase_1Hz-00.txt
This is the files that goes into the simpleRTK2Blite mounted on top of the simpleRTK2B in the kit. Note that depending on your previous configuration you might have to upload the configuration file twice, because in the middle of the configuration file there is a baudrate change.
Starting from a default ZED-F9P configuration:
- Disable SBAS, to avoid position jumps during short RTK corrections interruptions.
- Disable Beidou, to make it simpler to increase navigation rate to 5Hz without troubles.
- UART1 and UART2 increased to 115kbps
- Activated following RTCM messages on UART1, which is connected from the simpleRTK2Blite to the UART2 of simpleRTK2B:
- 1077: GPS MSM7
- 1087: GLONASS MSM7
- 1097: GALILEO MSM7
- 1230: GLONASS code-phase
- 4072.0: Reference station PVT (u-blox proprietary RTCM Message)
- 4072.1: Additional reference station information (u-blox proprietary RTCM Message)
- Enabled UBX-NAV-RELPOSNED to read relative positions.
Filename simpleRTK2B_FW113_HeadingKit_Rover_1Hz-00
Starting from a default ZED-F9P configuration:
- UART1 and UART2 increased to 115kbps
- Disable NMEA messages in all interfaces, to avoid buffer overflow
- Enabled on USB and UART1:
- UBX-NAV-RELPOSNED
- UBX-NAV-PVT
Filename simpleRTK2B_FW113_Bluetooth-00.txt
Starting from a default ZED-F9P configuration:
- Disable SBAS, to avoid position jumps during short RTK corrections interruptions
- UART2 activate NMEA output via UBX-CFG-PRT
- Activate GST so accuracy estimates are also visible
- Enabled High Precision NMEA with one extra decimal digit
Filename simpleRTK2B_FW113_simpleSSR_1Hz-00.txt
- UART1 outputs GGA and ZDA. (XBee switch must be on “XBEE TO GPS UART1”).
- UART2 disabled. Can be enabled from UBX-CFG-PRT.
- USB outputting NMEA+UBX.
Filename simpleRTK2B_FW113_simpleSSR_10Hz-00.txt
- UART1 outputs GGA and ZDA. (XBee switch must be on “XBEE TO GPS UART1”).
- UART2 disabled. Can be enabled from UBX-CFG-PRT. Increase baudrate to avoid buffer overflow at 10Hz. Contact us if in doubt.
- USB outputting NMEA+UBX.
