rtcm.org can provide you with the full specification standard


They use a binary packet format, and this is independent of the UBX format. The receiver can output and process packets interleaved in UBX, RTCM3 and NMEA forms


Its usually not necessary to understand the internal payload to process and transport the packets, I’ve posted examples to the uBlox forum related to this, and I’ve attached some code examples here related to them. The payload format is non-trivial, and bit-wise, but is documented.
