Sgp4 Python Packages

kshana

Open, validated, reproducible PNT-resilience simulator spanning the full positioning, navigation & timing stack — orbit, clocks, INS, GNSS, integrity, resilience, lunar/cislunar & deep-space nav — plus quantum-vs-classical models. Runs as a Rust lib/CLI, Python, in-browser (WASM), an MCP server / Claude Code plugin, and a JetBrains plugin.

orbit-predictor

Python library to propagate satellite orbits.

astroz

Astrodynamics and Spacecraft Toolkit. Features fast orbit prop, celestial precession, CCSDS parsing, RF parsing, fits image parsing, and more!

gpconf

Free test kit: does your satellite software handle catalog numbers above 99,999? Built from real CelesTrak data.

sgp4-predict

Predict functionality for orbital events and windows based off of SGP4.

astrodynamics-mcp

Model Context Protocol server giving any LLM client (Claude, ChatGPT, Cursor, agents) authoritative astrodynamics tools — TLE/SGP4, Lambert, ground-station access, time/frame conversions, porkchop, B-plane.

dsgp4

dSGP4: differentiable SGP4. Supports differentiability, ML integration & embarassingly parallel computations

orbit-formats

Lossless round-trip across orbital state-vector and ephemeris formats — TLE, CCSDS NDM, SP3, SPK, STK ephemeris, GMAT report.

maneuver-detect

Open dataset, baselines, and leaderboard for detecting satellite maneuvers from public TLE history.

kessler-toolkit

Open orbital conjunction assessment - parses satellite collision warnings (CDMs), computes collision probability two independent ways (Foster x Chan), and ranks what matters. Live on real Space-Track data.
