RUNNER-1 (TYVAK-1005)

RUNNER-1 (TYVAK-1005) is an active satellite operated by IMAG / FACh (Israel), launched on 2023-06-12 from Vandenberg Space Force Base, United States on the Transporter-8 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 441 km and 451 km with an inclination of 97.6°. It travels at approximately 27,528 km/h (7.65 km/s), completing one full orbit every 94 minutes — that’s roughly 15.40 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 RUNNER-1 (TYVAK-1005) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

RUNNER-1 (TYVAK-1005) orbits at an average altitude of 446 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 RUNNER-1 (TYVAK-1005)’s average altitude, there are currently 10,480 active payloads and 149 tracked debris or rocket body fragments — notable neighbours include ISS (ZARYA), STARLINK-1017, STARLINK-1039. This makes it one of the more crowded altitude bands, containing roughly 55.3% of all active satellites. With an inclination of 97.6°, RUNNER-1 (TYVAK-1005) passes over latitudes between 97.6°N and 97.6°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. Israel operates approximately 11 active satellites in total.
