Page 4: Introduction
Space Track. The TLE format is a standard for distribution of an Earth-orbiting object's orbital elements. TLEs can describe the trajectories only of earth orbiting objects. Note: TLE data becomes less accurate with age and must be updated regularly. AvL Technologies | Proprietary – Content is Subject to Change without Notice... -
