A Python script for decoding downlinked .bin telemetry log files from Argus. The script parses subsystem-specific binary Data Handler files, originally packed using struct.pack in the onboard flight software and converts them into human-readable .csv files for analysis. Useful for batch processing logs from long-duration DITL or TVAC tests.
python main.py -i ./logs -o ./converted_logs-i/--input: Path to the top-level input folder containing subsystem folders (e.g., logs/adcs, logs/eps, etc.)-o/--output: Path to the top-level output folder where .csv files will be saved, preserving the directory structure
- Supports all key subsystems:
adcs,cdh,cmd_logs,comms,eps,eps_warning,gps, andhal
- Recursively scans a directory containing subsystem folders with
.binlog files - Decodes binary files using appropriate
structformat for each subsystem - Outputs
.csvfiles with corresponding headers in a mirrored output directory structure.
- Each subsystem has a known binary format (
STRUCT_FORMATS) and field definitions (FIELDS). - The script uses Python's
structmodule to unpack binary records from.binfiles. - It creates a matching
.csvfile for each.binfile, with a header row and data rows. - Output
.csvfiles are written to a new directory that mirrors the structure of the input log directory.
