- NORAD Two-Line Element Set Format - CelesTrakNORAD Two-Line Element Set Format. Data for each satellite consists of three lines in the following format: Line 0 is a twenty-four character name (to be consistent with the name length in the NORAD SATCAT). Lines 1 and 2 are the standard Two-Line Orbital Element Set Format identical to that used by NORAD and NASA. The format description is:
- Two-line element set - WikipediaA two-line element set ( TLE, or more rarely 2LE) or three-line element set ( 3LE) is a data format encoding a list of orbital elements of an Earth-orbiting object for a given point in time, the epoch. Using a suitable prediction formula, the state (position and velocity) at any point in the past or future can be estimated to some accuracy.
