📖 About This Object
NSS 513 (INTELSAT 513) is an active satellite operated by Intelsat (Netherlands), launched on 1988-05-17 from Guiana Space Centre, Kourou. With over 38 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,218 km and 36,322 km with an inclination of 14.7°. It travels at approximately 11,007 km/h (3.06 km/s), completing one full orbit every 24.3 hours — that’s roughly 0.99 orbits per day. It is part of the Intelsat constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks NSS 513 (INTELSAT 513) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
NSS 513 (INTELSAT 513) occupies geostationary orbit at approximately 35,786 km above the equator, where its orbital period matches the Earth’s 24-hour rotation. From the ground, it appears to hover over a fixed point — ideal for broadcast television, weather monitoring and wideband communications. With an inclination of 14.7°, it traces a small figure-of-eight pattern relative to the equator rather than remaining perfectly stationary, which can indicate aging stationkeeping fuel or a deliberate inclined-orbit strategy. Within ±50 km of NSS 513 (INTELSAT 513)’s average altitude, there are currently 53 active payloads and 12 tracked debris or rocket body fragments. Netherlands operates approximately 7 active satellites in total.
❓ Frequently Asked Questions
NSS 513 (INTELSAT 513) orbits at approximately 36,270 km altitude, where the orbital period matches the Earth’s 24-hour rotation. This means it stays above the same point on the equator at all times. Its actual speed is still 11,007 km/h — it just keeps pace with the ground below. With an inclination of 14.7°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed. Learn more about geostationary orbits.
NSS 513 (INTELSAT 513) is operated by Intelsat (Netherlands). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 19121. You can track NSS 513 (INTELSAT 513) in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
NSS 513 (INTELSAT 513) was launched on 1988-05-17 from Guiana Space Centre, Kourou, the European spaceport in French Guiana, chosen for its equatorial location which provides an energy-efficient boost for orbital insertions. View the full satellite launch log.
Yes — Orbital Radar tracks NSS 513 (INTELSAT 513) (NORAD ID 19121) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time. You can also browse the satellite directory to find other tracked objects.
NSS 513 (INTELSAT 513) travels at approximately 11,007 km/h (6,839 mph) — roughly 3.06 km/s. Despite this high speed, it appears stationary from the ground because it matches the Earth’s rotation. Geostationary satellites are actually slower than LEO satellites because orbital velocity decreases with altitude.
NSS 513 (INTELSAT 513) is a member of the Intelsat constellation. Satellites in this group work together to provide coordinated coverage, typically in similar orbital planes at comparable altitudes. You can view all Intelsat satellites on Orbital Radar’s live tracker.
