What is a TLE (or 2LE or 3LE)?

TLE or 2LE: Two-Line Element Set

3LE: Three-Line Element Set

TLEs are used to describe the orbits of Earth-orbiting objects. They are used by the United States Department of Defense to track objects in orbit.

Recent TLEs for most objects can be found at the following websites:

• Space-Track
• Celestrak
• N2YO
