SBET-decoder

SBET-decoder converts binary Smoothed Best Estimated Trajectory (SBET) files and associated accuracy files into plain-text tables.

The repository provides two command-line tools:

• sbet-decoder: decodes SBET trajectory entries.
• accuracy-decoder: decodes SBET accuracy entries.

Current project version is stored in VERSION. Versioning rules are documented in VERSION.md.

Requirements

• Linux: g++, make
• Optional for API docs: doxygen
• Windows (native build): Visual Studio C++ Build Tools and nmake/make

Build

make

This produces:

• build/bin/sbet-decoder
• build/bin/accuracy-decoder

Run

build/bin/sbet-decoder path/to/file.out > sbet.txt
build/bin/accuracy-decoder path/to/file.out > accuracy.txt

If no input file is provided, each binary prints usage information.

Tests

make test

Test reports are written to:

• build/test/reports/sbet-test-linux-report.xml

Documentation

Generate Doxygen documentation:

make doc

Additional format examples are documented in doc/README.md.

CI

Continuous integration is provided with GitHub Actions in .github/workflows/ci.yml. It uses GitHub-hosted runners only (no self-hosted runner required). The workflow validates:

• Linux build and tests
• Windows build and tests
• Doxygen documentation generation
