T2V

T2V is an active satellite operated by Thailand, launched on 2023-10-09 from Guiana Space Centre, Kourou. It orbits in Low Earth Orbit (LEO) at altitudes between 623 km and 625 km with an inclination of 97.9°. It travels at approximately 27,175 km/h (7.55 km/s), completing one full orbit every 97 minutes — that’s roughly 14.82 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 ~10–25 years. Orbital Radar tracks T2V in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

T2V orbits at an average altitude of 624 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 T2V’s average altitude, there are currently 827 active payloads and 797 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-3055, STARLINK-3109. With an inclination of 97.9°, T2V passes over latitudes between 97.9°N and 97.9°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. Thailand operates approximately 13 active satellites in total.
