NANOSAT C BR1

NANOSAT C BR1 is an active satellite operated by Brazil, launched on 2014-06-19 from OREN. After 12 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 468 km and 474 km with an inclination of 98.1°. It travels at approximately 27,478 km/h (7.63 km/s), completing one full orbit every 94 minutes — that’s roughly 15.32 orbits per day. Its near-polar, sun-synchronous orbit means it passes over any given point on Earth at approximately the same local solar time, ideal for consistent Earth observation lighting conditions. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks NANOSAT C BR1 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

NANOSAT C BR1 orbits at an average altitude of 471 km in a sun-synchronous orbit (SSO), a specialised subset of LEO where the orbital plane precesses to maintain a constant angle relative to the Sun. This provides consistent lighting conditions on every pass — essential for Earth observation, weather monitoring and environmental science. Within ±50 km of NANOSAT C BR1’s average altitude, there are currently 7,923 active payloads and 196 tracked debris or rocket body fragments — notable neighbours include STARLINK-1017, STARLINK-1039, STARLINK-1047. This makes it one of the more crowded altitude bands, containing roughly 45.5% of all active satellites. With an inclination of 98.1°, NANOSAT C BR1 passes over latitudes between 98.1°N and 98.1°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. Brazil operates approximately 31 active satellites in total, of which 5 share a similar altitude band with NANOSAT C BR1.
