Visualize GNSS data in a web browser

About the project
GNSS visualizer is a tool for visualizing GNSS data in an interactive environment.
It is designed to offer a simple interface in a web browser with ever extending plotting capabilities.
Built with
The interface and all the plots are built using awesome Bokeh library.
Parsing of ubx messages leverages pyubx2 library.
Getting started
Installation via pip
python -m pip install gnss-visualizer
Usage
After installing, the tool provides a command gnss-visualizer
that can be used to launch the tool and open the UI in a web browser.
Reading ubx files
Analyzing an ubx file can be done in the following way:
gnss-visualizer ~/path/to/file.ubx -w 1
where -w (shorthand for --simulate-wait-s) is used to add delay of 1 second after each UBX-NAV-PVT message. This will make files with 1 Hz navigation rate playback as if they were done in (almost) realtime.
The input file should contain UBX-NAV-PVT message and in order to generate signal and satellite based plots also UBX-NAV-SIG message.
Reading serial devices
Data can be read also from a serial device using:
gnss-visualizer /dev/ttyUSB0
Details
gnss-visualizer
command can be substituted to bokeh serve src/gnss_visualizer --show --args INPUT
and in case the bokeh serve command needs to be modified, it can simply be used manually instead of calling gnss-visualizer
.
Roadmap
- Tests
- Github CICD
- Plot selection mechanism
- Make plotting module with classess for different plots
- Set up whole file reading for timeseries plots
- More plots
- Allow playback after reading the whole file
- Configurable wait delay
- Non-ubx file support (some basic plots?)
- Even more plots
- Truth location handling (coordinates / files)
- Lots more plots
- UI for file input
See the open issues for a full list of proposed features (and known issues).
