📖 About This Object
INTELSAT 507 is an active satellite operated by ITSO, launched on 1983-10-19 from Guiana Space Centre, Kourou. With over 43 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,935 km and 35,966 km with an inclination of 12.1°. It travels at approximately 11,048 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. It is part of the Geo Protected constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks INTELSAT 507 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
INTELSAT 507 occupies geostationary orbit (GEO) at approximately 35,786 km above the equator. At this precise altitude, the satellite’s orbital period matches the Earth’s rotation — so it appears to hover over a fixed point on the equator. GEO is used primarily for broadcast television, weather monitoring (Meteosat, GOES) and wideband communications. Only about 560 active satellites occupy the GEO belt, but its commercial value is immense: a single GEO slot can cover roughly one-third of the Earth’s surface. This satellite has a non-zero inclination of 12.1°, meaning it traces a small figure-of-eight pattern relative to the ground rather than remaining perfectly stationary. This can indicate an aging satellite whose stationkeeping fuel is running low, or a deliberate inclined-orbit strategy to extend operational life.
🔗 Intelsat Communications

This satellite is operated by Intelsat, one of the pioneering commercial satellite operators, with a fleet of 50+ geostationary satellites providing television distribution, enterprise networking, mobility connectivity and government communications worldwide. Intelsat was founded in 1964 as an intergovernmental organisation and privatised in 2001.

❓ Frequently Asked Questions
INTELSAT 507 orbits at approximately 35,951 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 11,048 km/h — it just keeps pace with the ground below. With an inclination of 12.1°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed.
INTELSAT 507 is operated by ITSO. It is catalogued by the U.S. Space Surveillance Network under NORAD ID 14421. You can track INTELSAT 507 in real time on Orbital Radar’s live tracker.
INTELSAT 507 was launched on 1983-10-19 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.
Yes — Orbital Radar tracks INTELSAT 507 (NORAD ID 14421) 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.
INTELSAT 507 travels at approximately 11,048 km/h (6,865 mph) — roughly 3.07 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.
INTELSAT 507 is a member of the Geo Protected constellation. Satellites in this group work together to provide coordinated coverage, typically in similar orbital planes at comparable altitudes. You can view all Geo Protected satellites on Orbital Radar’s live tracker.
