To have an orbital path that results in a satellite staying above one particular point on Earth's surface - a geostationary orbit - requires further constraints to be obeyed, not just a geosynchronous orbit. A two-line element set (TLE) is a data format encoding a list of orbital elements of an Earth-orbiting object for a given point in time, the epoch. 2: The major axis of an elliptical orbit about the Earth. Two-Line Element (TLE) is a data format or a way of encoding various parameters of an object orbiting Earth at any particular time point, an epoch.

All satellites have their GEC coordinates given in "Two line elements" (TLE) data.
