DB-WALI-WMU

DB-WALI-WMU is an active satellite operated by NearSpaceLaunch (United States), launched on 2026-03-30 from Vandenberg Space Force Base, United States on the Transporter-16 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 507 km and 515 km with an inclination of 97.5°. It travels at approximately 27,398 km/h (7.61 km/s), completing one full orbit every 95 minutes — that’s roughly 15.18 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 ~3–10 years. Orbital Radar tracks DB-WALI-WMU in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

DB-WALI-WMU orbits at an average altitude of 511 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 DB-WALI-WMU’s average altitude, there are currently 9,959 active payloads and 263 tracked debris or rocket body fragments — notable neighbours include STARLINK-1039, STARLINK-1184, STARLINK-1231. This makes it one of the more crowded altitude bands, containing roughly 53.3% of all active satellites. With an inclination of 97.5°, DB-WALI-WMU passes over latitudes between 97.5°N and 97.5°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. United States operates approximately 13,204 active satellites in total, of which 9,293 share a similar altitude band with DB-WALI-WMU.
