v1.0

[v1.0] - 2025-11

Summary

This is the first full release of the PoISE consensus mechanism. This has been released to accompany a presentation at the 2026 SciTech Forum.

Added

• Pytest unit tests for all code.
• Moved plotting into its own file.
• Correctness score now accounts for average NIS, following chi-squared statistics
• Reputation is now based on chi-squared statistics for bounds, and previous behaviour
• Simulates faulty and malicious nodes in accord_demo.py
• Uses a simpler EKF implementation with Filterpy

Full Changelog: v0.2.1...v1.0

v0.2.1

[v0.2.1] - 2025-10

Summary

This is a patch release of the PoISE consensus mechanism, providing key bug fixes.

Added

• Bug fix in od_filter.py to allow LOS only measurements to be processed correctly.
• Additional plots for chi2 functions and consensus scores.

v0.2

[v0.2] - 2025-09

Summary

This is the second proof-of-concept release of the PoISE consensus mechanism, using MATLAB for generating satellite simulation data and a second order extended kalman filter with a state transition tensor for orbit determination calculations.

Added

• Replaced TLE data inputs with simulated sensor data created by a MATLAB script.
• Implemented a Second Order Extended Kalman Filter with State Tranisiotn Tensor for permising Orbit Determination Calculations.
• Added the Normalised Innovation Score (NIS) to the consensus mechanism calculations.
• Simulation of both good and malicious data submissions for a small network of satellites.
• Generation of plots showing:
  • Chi Squared probability distributions
• Addition of logging.
• Additional configuration for linting and type checking tools.
• Created new diagrams describing the orbit determination process.

v0.1

This is the first proof of concept release of the PoISE consensus mechanism. It:

• Uses TLE data to propagate orbital data using sgp4 and the skyfield library
• For one satellite, simulates the submission of good and malicious data
• Creates plots of the DAG structure and the satellite reputation
• Uses asyncio for asynchronous message communications
