This site shows orbits of satellite tracked by NORAD. It uses TLE parsed with satellite-js. You can import any TLE or search throuh a list of active satellites retrieved from Celestrak.com. You can visualize orbits in ECEF or ECI coordinate. Augmented Reality (AR) view from your location is currenlty in beta.
Sun position is estimated from current time and date. Earth tilt "vary" form -23.45° (December 22) to +23.45° (June 21). Today tilt is calculated with this equation.
