GET /iss/tle

Get the Two-Line Element (TLE) set for the International Space Station - the standard format used to describe satellite orbits. TLE data includes orbital inclination, eccentricity, argument of perigee, mean motion, and epoch. Used by satellite tracking software (like SGP4 propagators) to predict the ISS position at any future time. Essential for building custom orbital prediction tools and pass-time calculators.
