📖 About This Object
ANIK B1 (TELESAT-4) is an active satellite operated by Telesat (Canada), launched on 1978-12-16 from Cape Canaveral, Florida. With over 48 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,846 km and 35,989 km with an inclination of 9.5°. 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. It is part of the Telesat constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks ANIK B1 (TELESAT-4) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
ANIK B1 (TELESAT-4) 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 9.5°, 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 ANIK B1 (TELESAT-4)’s average altitude, there are currently 65 active payloads and 16 tracked debris or rocket body fragments. Canada operates approximately 67 active satellites in total, of which 2 share a similar altitude band with ANIK B1 (TELESAT-4).
❓ Frequently Asked Questions
ANIK B1 (TELESAT-4) orbits at approximately 35,918 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 9.5°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed. Learn more about geostationary orbits.
ANIK B1 (TELESAT-4) is operated by Telesat (Canada). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 11153. You can track ANIK B1 (TELESAT-4) in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
ANIK B1 (TELESAT-4) was launched on 1978-12-16 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 ANIK B1 (TELESAT-4) (NORAD ID 11153) 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.
ANIK B1 (TELESAT-4) travels at approximately 11,052 km/h (6,868 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.
ANIK B1 (TELESAT-4) is a member of the Telesat constellation. Satellites in this group work together to provide coordinated coverage, typically in similar orbital planes at comparable altitudes. You can view all Telesat satellites on Orbital Radar’s live tracker.
