A 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.

A set of graphs and tables that show everything from the age distribution of the latest GP data, recently decayed objects, lost objects, restricted objects, and the mean historical age of each GP update since 2005 Oct 21.

Jul 1, 2022 · 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: All other columns are blank or fixed.

Oct 2, 2023 · Two Line Element Set (TLE) is the data format to describe the orbital parameters of the earth-orbiting object. The example of TLE for ISS: First line is Line 0, thus this is called two-line element set. Then, for each element. Line 0 includes only the …

Welcome - thousands of Satellites and countless other objects (including the Moon) are orbiting our Planet right now, use this web site to browse active Satellite information derived from TLE orbit data and other public domain resources.

Two-Line Element Sets (TLEs) form the cornerstone of satellite tracking. They’re the lifeblood for anyone needing to understand, predict, and visualize the trajectories of satellites orbiting Earth. Tles provide a compact but comprehensive snapshot of a satellite’s orbital parameters.

With the TLEs and your station location, you can compute when the satellite will be in view and where to point your antennas. See the tutorial on Keplerian elements and the explanation of the formats used in these files.

"Satellite Catalog Number" comes from the early days of satellite identification done at Hanscom Field, Massachusetts, USA in the late 1950's, where they kept track of the satellites they identified, by giving them the next ascending number in a log that began with the number 00001

5 days ago · The Satellite Database archives orbital data of satellites and other space objects in the form of Two-Line Elements. The data is fetched from CelesTrak on an hourly basis. The data can be searched and retrieved using the search form on this website or the API.

A Two-Line Element Set, or TLE, is an ancient method, originally designed for computer punchcards, to describe satellite orbits. Despite it’s age, this format continues to be commonly used, likely because it is a compact way of describing satellite orbits with sufficient accuracy for most applications.
