CubeSat P-POD Detumble Simulator

Watch a freshly-ejected CubeSat tumble chaotically after P-POD deployment, then compare a passive bar-magnet detumble against an active B-dot magnetorquer controller side by side on a live angular-velocity chart.

Controls1U/2U/3U size buttons pick the CubeSat body and its inertia tensor; 'Eject from P-POD' randomizes a fresh tumble on all three axes. Three mode buttons (No detumble / Passive bar magnet / Active B-dot magnetorquer) run in parallel from the same ejection and select which one drives the 3D view and readouts, so their decay curves are directly comparable on the live chart. Sim-speed slider scales time; stat boxes show |ω|, orbits elapsed, sun-pointing accuracy, power generation % and antenna-Earth lock.

Eject a 1U/2U/3U CubeSat from a P-POD deployer and watch it tumble on all three axes, then compare a passive bar-magnet detumble against an active B-dot magnetorquer side by side on a live angular-velocity chart, with power generation recovering only once the solar panel settles toward the sun.

Eject a 1U/2U/3U CubeSat from a spring-loaded P-POD deployer and watch it tumble chaotically on all three axes, then compare a passive bar-magnet detumble against an active B-dot magnetorquer controller side by side on a live angular-velocity-vs-time chart, with solar power and antenna lock only recovering once the body settles and its panel tracks the sun.
