Logging on USB

[bastien vincke]

Hi,

I am a new user of Piksi multi and I would like to record the RTCM stream directly on a USB stick.

I configured the GPS using Swift Console. I activated "standalone logging", selected the right directory and in USB0 I selected RTCMv3 OUT. 

I do have a file that is created on the USB stick (.sbp file). However, I have in this file some amazing parts of the type : 

GPS L1CA 9 Outlier removed: obs type 0;

or

~(robust_estimator.cc:230) Outlier detected on index 6; residual -5.581, residual variance 1.099877, variance factor: 2

These parts are not from RTCMv3 and should not be in this file.

What must be done to have a well saved file?

Thank you!

Hello,

Unfortunately, the device only logs raw SBP to the flash drive with the "standalone logging" feature. 

However, you can use our sbp2rinex to convert to RINEX. https://support.swiftnav.com/support/solutions/articles/44001907895-sbp-to-rinex-converter-and-data-post-processing

Swift provides  some open source tools to convert the SBP file to RTCMv3 (https://github.com/swift-nav/gnss-converters) 
Additionally, If you are familiar with RTKLIB (https://github.com/swift-nav/RTKLIB) there should be a way to convert the file as well.
Lastly, you might consider using one of the many UART / RS-232 to sdcard products to record the RTCMv3 serial stream from the device itself (https://www.slerj.com/ssr-lc.html?gclid=EAIaIQobChMI7tb6o-Sg6gIV7R-tBh09RAVwEAQYASABEgK0UPD_BwE)

Hope this helps!
