PyGPSClient is a graphical GNSS/GPS testing, diagnostic and configuration application for Linux and other platforms. It is aimed at users who need to work directly with GNSS receivers rather than simply display a position on a map.
The application can connect to physical receivers, network sources and previously recorded data streams, providing a central interface for examining receiver output and configuring supported hardware. This makes it useful for experimenting with GNSS equipment, diagnosing receiver behaviour, working with high-precision positioning and analysing recorded data. Its tkinter interface combines receiver information, satellite data, maps, console output and configuration controls.
This is free and open source software.
Key Features
- Supports NMEA, UBX, SBF, UNI, QGC, RTCM3, SPARTN, NTRIP and ASCII TTY protocols.
- Provides an NTRIP client for receiving RTCM3 and SPARTN correction data.
- Can operate as an NTRIP base station with compatible RTK receivers.
- Configures supported u-blox, Quectel, Septentrio, Unicore and Feyman GNSS devices.
- Displays console data in parsed, binary, hexadecimal and combined formats.
- Records GNSS data to timestamped log files.
- Records position data as GPX tracks.
- Includes a GPX track viewer.
- Provides experimental conversion of raw observation, navigation and meteorological data to RINEX.
- Supports decimal degrees, degrees/minutes/seconds, degrees/decimal minutes and ECEF position formats.
- Offers metric, imperial and maritime measurement units.
- Saves and restores application configuration settings.
- Supports user-defined receiver configuration presets.
- Can process previously captured binary GNSS data.
- Cross-platform support – runs on Linux, macOS, and Windows.
