A browser-based tool that couples orbital, thermal, power, attitude, and ground-station analysis for CubeSats in low Earth orbit.

CMAT turns one spacecraft-and-orbit specification into linked mission results, keeping dependencies such as eclipse, battery margin, and orbital decay explicit instead of reconciling separate studies by hand. It is unusually candid about its limits: specialised for CubeSats in low Earth orbit, aimed at concept and feasibility work, and not a substitute for design verification.
