mission-analysis

PyKEP is a scientific library providing basic tools for research in interplanetary trajectory design.

Oxidized Astrodynamics

Sophisticated astrodynamics and space mission simulator. Calculate n-body trajectories, perform orbital maneuvers, apply various perturbations, generate plots, and more! Minimal dependencies.

Satellite Mission Analysis and Design

Spacecraft Orbital Computations Kit (SpOCK)

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.

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

Python toolkit demonstrating GNSS mission-analysis concepts: Walker Delta notation, constellation availability, and simplified Galileo-altitude manoeuvre budgeting.

Run parameter sweeps and Monte Carlo dispersions over GMAT missions in parallel from Python.

Run GMAT mission scripts from Python and get results as pandas DataFrames.

Orbital Simulation - Takeoff to Lunar Transfer - Fully Plotted - Highly Flexible

This repository implements high-fidelity numerical solvers and optimization algorithms for interplanetary trajectory design and near-Earth orbital maintenance.

Browser-based solar-system visualization, sky-event guidance, validation, and preliminary mission analysis suite.

Preliminary Mission Analysis Tool for Sun-Synchronous Orbit (SSO) Earth Observation Constellations.

Interactive stability analysis framework for detecting destabilizing forces, coupling effects, and intervention opportunities in complex systems.

System level conceptual design of a reusable space launcher, with responsibility for subsystem integration and overall coordination

HERMES is a satellite constellation enabling high-speed communication and navigation between Earth and the Moon, focused on the lunar far side. Operating from a Halo orbit at Earth–Moon L2, it ensures continuous coverage and supports future lunar missions with a scalable architecture.

Interactive Python tool that computes asteroid rendezvous launch windows using Lambert transfers, Earth ephemerides, and user-defined orbital elements.

End-to-end MATLAB mission analysis of a crewed lunar return: Hohmann transfer and phasing, Clohessy-Wiltshire proximity operations, J2 and third-body perturbations, CR3BP verification, and a 5R berthing manipulator. Verified against closed-form solutions; 32-page report and an 89 s showreel included.
