1 lip 2022 · Learn how to use NORAD two-line element sets (TLEs) to predict satellite positions and velocities. Find the description, format, checksum, and history of TLEs, as well as alternative data sources and prediction models.
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. Learn about the history, format and usage of TLEs, and how they are related to NORAD and SGP models.
1 dzień temu · Search and retrieve orbital data of satellites and other space objects in the form of Two-Line Elements (TLEs) from CelesTrak. Filter by date, name, NORAD ID, frequency and more.
CelesTrak's mission remains focused on making data and other resources freely available to the space community to facilitate understanding of our orbital environment and how to use it safely and responsibly. We are committed to enhancing our current visualization tools and upgrading SOCRATES to integrate with those tools.
NASA i NORAD na bieżąco podają nowe efemerydy zapisywane w systemie TLE. Dzięki informacjom zawartym w TLE, można przy użyciu specjalnych programów komputerowych wyznaczyć dokładne położenie danego satelity w czasie i przestrzeni.
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. Understanding the Basics of TLEs.
