Симулятор орбитального сближения и стыковки с 6-DOF физикой

Build a real-time orbital rendezvous and docking simulator in the browser. A chaser spacecraft must approach and dock with a target spacecraft in orbit around Earth. Propagate true motion with two-body physics in an Earth-centered inertial frame, and use a Hill-Clohessy-Wiltshire model in the local orbital frame only for guidance and transfer planning. Give the chaser full six-degree-of-freedom rigid-body dynamics with quaternions, fuel use, and force and torque limits, so all motion comes from closed-loop control rather than set positions. Add a navigation estimator, a safety and capture check with a docking cone, and a self-grading panel. Provide a dark HUD with telemetry, phase indicator, live graphs, several camera views and buttons to pause, restart with a new seed and toggle debug. Done when it docks reliably across seeds.
