GNSS modules can be configured to continuously stream data in raw data format for PPP purposes. The data is initially recorded via u-center with the below configuration messages. Then the file can be used for post-processing with the help of RTKLib.

For raw data recording, you may activate the following messages to obtain .ubx data:

  • UBX to USB

  • UBX to UART (We prefer using UART1, whilst UART2 is not viable for raw data processing)

Menu -> View → Configuration View → MSG (Messages): 1. Select Message “02-10 RXM-RAW”, and check USB. Then click on the “Send” button at the bottom left of the Messages window. 2. Select Message “02-11 RXM-SFRB”, and check USB. Then click on the “Send” button at the bottom left of the Messages window. 3. Select Message “02-30 RXM-ALM” and check USB. Then click on the “Send” button at the bottom left of the Messages window. 4. Select Message “02-31 RXM-EPH” and check USB. Then click on the “Send” button at the bottom left of the Messages window.

Finally, Menu -> View → Configuration View → CFG (Configuration): Save to current configuration, Select all devices. Then click on the “Send” button at the bottom left of the Configuration window.
