Puslib is a Python implementation of the telemetry and telecommand packet utilization standard (PUS). It is a standard widely used in the space industry for the purposes of remote monitoring and control of spacecraft subsystems and payloads.
This package is mainly intended for ground segment tools, e.g.:
- data extraction and post-processing of telemetry.
- simulators.
- EGSE SW, and thus enabling the use of mission control systems for controling and monitoring of EGSE equipment.
- enable Python based commanding for mission control systems and other PUS based systems.
- mission-specific tools.
- student projects.
pip install puslibPython 3.7 or later is required.

print(packet)- CCSDS packet handling (telecommands and telemetry packets)
- CCSDS Unsegmented Time Code (CUC) support
- Policy handling of mission specific or implementation specific configurations
- Simple abstraction of application processes
- Streams for telemetry and telecommand I/O access
- PUS Services:
- PUS 1: Request Verification
- PUS 3: Housekeeping (partial support)
- PUS 5: Event Reporting
- PUS 8: Function Management
- PUS 17: Test (partial support)
- PUS 20: On-board Parameter Management (partial support)
