RTCM Message format and CRC

Thanks Marco

I was using version 1.0 of the above document. I don’t think there’s that much difference between versions 1.0 and 1.1

Do you have more details about the CRC implementation used on LG290P for RTK messages ?
In my setup, i don’t use a dedicated RF link between base and rover

Rather, the base station sends RTK packets to a GCS (Ground control station), which in turn repackages it along with other messages and transmits it to the rover.
The rover after unpacking the message sends the RTK message to the rover. Therefore to send integral messages to the rover, it is necessary for me to ensure complete messages are packed from the base station, for which i need to know the CRC implementation.

The first reference you shared talks about possible CRC implementations, but could you confirm which specific one is used on LG290P ?
