pygnssutils is an original Python 3 library which reads, parses and broadcasts the NMEA, UBX or RTCM3 output of any GNSS receiver, as well as providing a variety of GNSS utility classes and functions.

It consolidates the common capabilities of three existing core GNSS protocol libraries from the same stable:

1. pynmeagps (NMEA Protocol)
2. pyubx2 (UBX Protocol)
3. pyrtcm (RTCM3 Protocol)

NB: pygnssutils does not replace these libraries. pynmeagps, pyubx2 and pyrtcm will continue to be developed as independent libraries for their specific protocol parsing and generation capabilities, but functionality which is common to all three (such as reading from a GNSS data stream, and certain helper classes and functions) will be incorporated into pygnssutils. The motivation is to reduce code duplication between these libraries, reduce maintenance and testing overheads, minimise churn on the core protocol libraries, and act as a framework for future generic GNSS capabilities.
