It reads RTCM3 messages from streams (serial, file, or socket), parses them into immutable RTCMMessage objects with named data fields (DF002, DF003, etc.), and exposes those fields as object attributes. The parser handles multiple signal messages (MSM) with configurable output formats (RINEX codes or frequency bands) and supports validation, error handling modes, and extensibility for additional message types.\n\nTypical usage involves creating an RTCMReader with a data stream and iterating through messages, or parsing individual binary RTCM3 frames directly. The library depends only on pynmeagps and installs as a pure Python wheel, making it portable across Windows, macOS, and Linux. It is actively maintained, supports Python 3.10 through 3.14, and carries no known security vulnerabilities.","worth_installing":"Yes. pyrtcm is production-stable, actively maintained, has low install friction, carries no known vulnerabilities, and is the only general-purpose RTCM3 parser in the Python ecosystem. Install it if you work with differential GNSS systems, RTK applications, or need to parse RTCM3 correction streams.
