Summary
BeiDou-3 I2-S launched on a China Aerospace Science and Technology Corporation Long March 3B/E from Launch Complex 3 (LC-3/LA-1), Xichang Satellite Launch Center, People's Republic of China on September 29, 2015. It was China Aerospace Science and Technology Corporation's 158th launch, 9th this year and humanity's 5,498th orbital launch attempt. It was the 15th Long March 3B/E flight and the 2nd this year. The payload was bound for Geostationary Transfer Orbit (GTO). Beidou DW 20, one of 2 catalogued objects, reached a 200 × 35,825 km orbit inclined 55.1°. 2 objects from this launch are catalogued, one of them a payload.
