What it is and what it does
pyubx2 is a parser and generator for the UBX binary protocol used by u-blox GNSS receiver modules. It reads and parses incoming UBX messages from streams (serial, file, or socket), returning both raw bytes and structured message objects. The package integrates support for NMEA 0183 and RTCM3 protocols via its runtime dependencies pynmeagps and pyrtcm, covering all output protocols that u-blox receivers produce.
The library divides UBX messages into three categories: GET (output from the receiver), SET (commands to the receiver), and POLL (queries to the receiver). It provides a UBXReader class for streaming and parsing, a static parse() method for individual messages, and utilities for generating and serializing messages. The package is readily extensible and implements a comprehensive set of messages for current u-blox devices.
Use it for
- Stream and parse real-time GNSS data from a u-blox receiver via file or socket.
- Read and decode UBX messages from a binary file for post-processing or analysis.
- Send configuration commands or queries to a u-blox receiver and parse responses.
- Handle mixed protocol streams containing UBX, NMEA, and RTCM3 messages.
- Extend the parser with custom UBX message definitions for non-standard outputs.
