📖 About This Object
INTELSAT 601 is an active satellite operated by Intelsat (ITSO), launched on 1991-10-29 from Guiana Space Centre, Kourou. With over 35 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,972 km and 35,986 km with an inclination of 13.4°. It travels at approximately 11,044 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 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 INTELSAT 601 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 601 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 13.4°, 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 INTELSAT 601’s average altitude, there are currently 49 active payloads and 26 tracked debris or rocket body fragments. ITSO operates approximately 72 active satellites in total, of which 6 share a similar altitude band with INTELSAT 601.
🔗 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 601 orbits at approximately 35,979 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 11,044 km/h — it just keeps pace with the ground below. With an inclination of 13.4°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed. Learn more about geostationary orbits.
INTELSAT 601 is operated by Intelsat (ITSO). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 21765. You can track INTELSAT 601 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
INTELSAT 601 was launched on 1991-10-29 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 INTELSAT 601 (NORAD ID 21765) 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.
INTELSAT 601 travels at approximately 11,044 km/h (6,863 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 601 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.
