Summary
Compass-IGSO-4 launched on a China Aerospace Science and Technology Corporation Long March 3A from Launch Complex 3 (LC-3/LA-1), Xichang Satellite Launch Center, People's Republic of China on July 26, 2011 at 21:44 UTC. It was China Aerospace Science and Technology Corporation's 87th launch, 5th this year and humanity's 5,145th orbital launch attempt. It was the 21st Long March 3A flight and the 2nd this year. The payload was bound for Geostationary Transfer Orbit (GTO). Beidou DW 9, one of 2 catalogued objects, reached a 204 × 35,735 km orbit inclined 55.1°. 2 objects from this launch are catalogued, one of them a payload.
