Everything a CubeSat mission needs

Space Mission Designer combines scientific-grade computation with an interactive web interface, so you can go from concept to validated mission analysis without leaving your browser.

Orbit Propagation

Choose the right propagator for the job. Use SGP4 with TLE or OMM elements for catalog satellites, or switch to high-fidelity numerical propagation powered by Orekit with J2, drag, and third-body perturbations. Propagate from minutes to months of mission time and inspect position, velocity, and classical orbital elements along the way.

Ground Station Access Analysis

Add ground stations anywhere on Earth and compute visibility windows automatically. Analyze pass duration, maximum elevation, and communication opportunities for single satellites or full constellations, and export results for link budget work.

Power & Data Budgets

Model solar array generation through orbit day and eclipse, track battery state of charge across the mission, and estimate data budgets from sensor activity and downlink opportunities. Verify your spacecraft closes its budgets before you build it.

Constellation Design

Generate Walker constellations or design custom architectures. Propagate every satellite in parallel, visualize the constellation in 3D, and evaluate coverage and revisit performance over regions of interest.

Attitude, Sensors & Footprints

Define attitude pointing modes, mount payload sensors on your spacecraft model, and project sensor footprints onto the Earth in real time to validate observation geometry.

Interactive 3D Visualization

Every analysis renders on an interactive Cesium-powered 3D globe. Scrub through time, inspect orbits and ground tracks, and present your mission the way it deserves to be seen.

TLE & OMM Satellite Import

Import real satellites from public catalogs using classic Two-Line Element sets or the modern CCSDS OMM format — no 5-digit NORAD ID limitation. Mix catalog satellites with your own designs in the same scenario.
