Mega-Constellations: Starlink, Amazon Leo, Guowang and Qianfan
What do the four largest constellations demand from the supply chain, and how do they differ?
Chapter summary
Starlink is effectively its own supply chain, building about 70 satellites a week and launching most of them on its own rockets.
Key takeaways
- 1
Amazon builds about 30 a week but cannot launch them fast enough and buys more parts from outside.
- 2
Guowang and Qianfan in China have factories rated in the hundreds a year but are limited by expendable rockets.
- 3
All four draw on merchant markets for semiconductors, cells, gases and some RF parts, and Amazon in particular is a large buyer of merchant components.
