📖 About This Object
SPAINSAT NG II is an active satellite operated by Spain, launched on 2025-10-24 from Cape Canaveral, Florida. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Highly Elliptical Orbit (HEO) at altitudes between 3,880 km and 69,800 km with an inclination of 13.8°. It travels at approximately 10,934 km/h (3.04 km/s), completing one full orbit every 24.8 hours — that’s roughly 0.97 orbits per day. Its orbital eccentricity of 0.7628 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks SPAINSAT NG II in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
SPAINSAT NG II follows a Highly Elliptical Orbit, sweeping between 3,880 km (perigee) and 69,800 km (apogee). It spends most of its 24.8 hours orbital period near apogee, effectively loitering over a region of interest before rapidly sweeping through perigee — a profile used for high-latitude communications (Molniya orbits), early-warning systems and magnetospheric science. Within ±50 km of SPAINSAT NG II’s average altitude, there are currently 7 active payloads and 2 tracked debris or rocket body fragments. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 13.8°, SPAINSAT NG II passes over latitudes between 13.8°N and 13.8°S, concentrating coverage over equatorial and near-equatorial regions. Low-inclination orbits maximise revisit rates over specific tropical zones. Spain operates approximately 53 active satellites in total.
❓ Frequently Asked Questions
SPAINSAT NG II follows a Highly Elliptical Orbit, swinging between 3,880 km (perigee) and 69,800 km (apogee). It spends most of its 24.8 hours orbital period near apogee, moving slowly at high altitude — effectively loitering over a region of interest before rapidly sweeping through perigee.
SPAINSAT NG II is operated by Spain. It is catalogued by the U.S. Space Surveillance Network under NORAD ID 66144. You can track SPAINSAT NG II in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
SPAINSAT NG II was launched on 2025-10-24 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 SPAINSAT NG II (NORAD ID 66144) 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.
SPAINSAT NG II’s speed varies dramatically throughout its orbit. At perigee it moves at its fastest, and at apogee it slows to a fraction of that — this is Kepler’s second law in action. Its average orbital velocity is approximately 10,934 km/h (3.04 km/s), completing one revolution every 24.8 hours. Learn more about highly elliptical orbits.
