之江实验室 三体计算星座
Zhejiang Lab's Three-Body constellation shares its first 12 satellites with ADA Space and added two more in July 2026, 14 in all. Its 2025 target of more than 50 satellites was missed by a wide margin, and its compute and link figures come from state and company sources.
Shared launches: Long March 2D (2025-05-14) with ADA Space.
Stage 6 of 7: Pathfinder constellation
14 constellation satellites have launched: 12 computing satellites on 14 May 2025 and 2 partner-built satellites (one computing, one remote sensing) on 24 Jul 2026.[1][2]
What the stage means: Several compute satellites flown as a network.
