How to select and access RTCM in LIV4F

[patrikpordi]

Hey!

I updated the firmware to the ME version, I am receiving some RTCM messages, but only a limited amount shows up in the message monitoring, also nothing can be decoded. Is there any documentation available on how to configure which RTCM messages should show up. I want to experiment with RTK calculations, so if there is any material on how to access and decode these RTCM messages would be highly appreciated.

Thanks is advance,

Patrik

The standards documents describing RTCM3 messages and formats of the MSM, are available for purchase from http://www.rtcm.org/

You could perhaps review tools like RTCM3TORINEX, PYRTCM or RTKLIB

I have the definitions, but the LIV4F only publishing a limited amount of them. My question is on how to configure the firmware to publish the rest.

Which do you actually need? A single MSMx for a given constellation, you don't need 4 thru 7, or whatever. They are different ways of expressing the same data, the 7's having the most precise data, the packets a little larger.

The table is for the "INPUTS" supported.

All stations get to see the same Ephemeris, so for RTK not a lot of value, for post-processing you can pull them from CORS.

Could be helpful for aiding in poor signal situations
