rudra3007-pro/ISRO-Satellite-Orbit-Tracker ? reverse-engineered prompt

Build me a single page interactive web app that lets me explore how satellites orbit Earth. I want a clean animated Earth with a starry background, a visible orbit path, and a satellite moving around it in real time. The app should let me start and stop the simulation, and change things like altitude, inclination, and eccentricity to see the orbit update instantly.

Please show the important orbit details on the page too, like latitude, longitude, altitude, apogee, perigee, orbital period, orbital velocity, and ground track shift. It would be great if there’s a simple mission picker with a few preset ISRO satellites like Cartosat 3, ResourceSat 2A, INSAT 3DR, AstroSat, Mangalyaan, and Chandrayaan 3, plus an option to enter custom values.

Make it feel polished and responsive, with smooth animation and easy to read info cards. Keep everything working in plain HTML, CSS, and JavaScript, and look up current docs online if you need to.
