+`pyubx2` is an original Python 3 parser for the UBX © protocol. UBX is a proprietary binary protocol implemented on u-blox ™ GNSS receiver modules. `pyubx2` can also parse NMEA 0183 © and RTCM3 © protocols via the underlying [`pynmeagps`](https://github.com/semuconsulting/pynmeagps) and [`pyrtcm`](https://github.com/semuconsulting/pyrtcm) packages from the same author - hence it covers all the protocols that u-blox GNSS receivers are capable of outputting.
