📖 About This Object
TELSTAR 302 is an active satellite operated by United States, launched on 1984-08-30 from Cape Canaveral, Florida. With over 42 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,913 km and 35,934 km with an inclination of 14.1°. It travels at approximately 11,052 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks TELSTAR 302 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
TELSTAR 302 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 14.1°, 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 TELSTAR 302’s average altitude, there are currently 59 active payloads and 16 tracked debris or rocket body fragments. United States operates approximately 12,360 active satellites in total, of which 20 share a similar altitude band with TELSTAR 302.
❓ Frequently Asked Questions
TELSTAR 302 orbits at approximately 35,924 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 11,052 km/h — it just keeps pace with the ground below. With an inclination of 14.1°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed. Learn more about geostationary orbits.
TELSTAR 302 is operated by United States. It is catalogued by the U.S. Space Surveillance Network under NORAD ID 15237. You can track TELSTAR 302 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
TELSTAR 302 was launched on 1984-08-30 from Cape Canaveral, Florida, one of the busiest launch facilities in the world, operated by NASA and the U.S. Space Force on Florida’s Atlantic coast. View the full satellite launch log.
Yes — Orbital Radar tracks TELSTAR 302 (NORAD ID 15237) 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.
TELSTAR 302 travels at approximately 11,052 km/h (6,867 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.
