Obtaining raw measurements from Liv4F (x-stm32mp-gnss2) using TaseoSuitePro7_3_3_1 Software

[jitusanwale]

HI,

I am using x-stm32mp-gnss2 evaluation board and interfaced with the host PC through UART to USB converter for utilizing the TaseoSuitePro7_3_3_1 Software.

I need following measurements for my college project:

1) Time of the measurement

2) Pseudo-range measurements 

3) Carrier phase

4) Ephemeris

5) Doppler frequency

I am not able to configure the liv4F for above output parameters. Request to suggest solution for obtaining these parameters.

Hi,

First step would be to program LIV4F with the ME firmware that you find in our release binary. You can set up the serial port as shown in the attachment so that it outputs RTCM and NMEA data.

For LIV4F we output Measurements in RTCM format. You would have to log this data and then use the log and run it using a free tool like CONVBIN to convert to RINEX to see this data. Please note this is post processing the log data.

If you need to read RTCM data, you need to refer to RTCM proprietary document to get visibility into bit fields. There are free versions available if you do a google search.

Hello,

I will also be using this evaluation board through UART to USB converter for sending RAW GNSS data in RTCM format to PC, in this case to apply rtk corrections on PC using rtklib. Did you manage to get it working? Any info would be great.

Thank you!

You can use RTKNAVI http://rtkexplorer.com/getting-started-with-rtknavi-2/.

RTKNAVI is a windows executable that you can feed RTCM stream from LIV4F and also use corrections streams from a base station to get precise position.

Yes I have gotten it to work on RTKNAVI.
