Summary
Beidou-3 IGSO-1 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 April 20, 2019. It was China Aerospace Science and Technology Corporation's 249th launch, 5th this year and humanity's 5,846th orbital launch attempt. It was the 29th Long March 3B/E flight and the 3rd this year. The payload was bound for Geostationary Transfer Orbit (GTO). Beidou DW 44, one of 2 catalogued objects, reached a 228 × 35,794 km orbit inclined 28.5°. 2 objects from this launch are catalogued, one of them a payload.
