About
Clyde Space (acquired by AAC Clyde Space in 2019, now part of AAC Clyde Space Group) is a UK pioneer in CubeSat electrical power systems (EPS), having designed and manufactured more flight-proven CubeSat power electronics than any other company globally. Based in Glasgow, Scotland, Clyde Space has delivered EPS and batteries to hundreds of CubeSat missions for universities, research agencies, and commercial satellite operators.
The company’s EPS product range covers 1U through 12U CubeSats, providing solar panel maximum power point tracking (MPPT), battery charging, regulated power bus generation (+3.3V, +5V, +12V rails), power distribution with fault protection, and real-time power telemetry. Clyde Space lithium polymer (LiPo) battery modules are space-qualified to a wide temperature range (-20°C to +60°C) and designed for 3–5 year operational lifetimes.
Clyde Space products have flown on missions for NASA, ESA, JAXA, and commercial operators including Planet Labs (Dove satellites used Clyde Space batteries in early generations), Spire Global, and iSPACE. The company’s product catalog covers the full power chain from solar arrays through batteries to distribution — making it a one-stop-shop for CubeSat power architects. AAC Clyde Space is listed on Nasdaq First North (Sweden).
