HIMAWARI 5 (GMS 5)

HIMAWARI 5 (GMS 5) is an active satellite operated by Japan, launched on 1995-03-18 from TNSTA. With over 31 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,004 km and 36,059 km with an inclination of 14.3°. It travels at approximately 11,038 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 0.99 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 HIMAWARI 5 (GMS 5) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

HIMAWARI 5 (GMS 5) 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 14.3°, 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 HIMAWARI 5 (GMS 5)’s average altitude, there are currently 74 active payloads and 29 tracked debris or rocket body fragments. Japan operates approximately 189 active satellites in total, of which 10 share a similar altitude band with HIMAWARI 5 (GMS 5).
