Summary
4 x SatNet test satellites launched on a China Aerospace Science and Technology Corporation Long March 2D from Launch Area 94 (SLS-2 / 603), Jiuquan Satellite Launch Center, People's Republic of China on April 1, 2025 at 04:00 UTC. The launch window ran from 03:52 to 04:29 UTC. It was China Aerospace Science and Technology Corporation's 514th launch, 13th this year and humanity's 6,918th orbital launch attempt. It was the 92nd Long March 2D flight and the 3rd this year. The payload was bound for low Earth orbit (LEO). Xingwang Jishu SW 06-01, one of 4 catalogued objects, reached a 455 × 465 km orbit inclined 55.0°. 4 objects from this launch are catalogued, all of them payloads.
