About
Built for the realities of commercial smallsat programmes
Long Arc Space Systems is a New Zealand space hardware company developing the CSS-1 Coarse Sun Sensor — a compact, flight-ready attitude sensing component for CubeSat and smallsat missions.
The CSS-1 is designed to compete directly with established components in the ±0.5° accuracy class, offering multiple mechanical variants to match common spacecraft interface footprints. Our focus is on delivering traceable qualification data, responsive support, and commercially viable pricing for mission teams at every scale.
