Hyperion Technologies

Hyperion Technologies, headquartered in Delft, Netherlands — adjacent to Delft University of Technology (TU Delft), one of Europe's leading aerospace engineering universities — is a Dutch smallsat component manufacturer founded in 2013 to commercialize miniaturized attitude determination and control system (ADCS) hardware for cubesats and small satellites, supplying flight-qualified sensors and actuators to satellite manufacturers globally.

Hyperion's product catalog covers the key hardware categories required for a complete small satellite ADCS: fine sun sensors (FSS) that measure Sun direction with sub-degree accuracy for attitude initialization and coarse pointing; star trackers (STR) that identify star field patterns to determine inertial attitude with arcsecond-level accuracy for precise Earth observation pointing; reaction wheels (RW) that store angular momentum and provide torque control for three-axis attitude stabilization; and magnetorquers (torque rods) that desaturate reaction wheels using Earth's magnetic field.

Each product line is available in multiple variants scaled for 1U through 16U cubesats and 1-100 kg small satellites, with radiation-tested components rated for LEO radiation environments.

Hyperion's miniaturization focus — achieving fine sun sensor and star tracker performance in form factors under 100 grams — addresses the fundamental constraint of 1U and 3U cubesats where mass and volume budgets are severely restricted. The company's star trackers achieve pointing accuracy better than 30 arcseconds with exposure times calibrated for rapidly rotating small satellites that cannot maintain precise pointing during star field capture. Reaction wheels are available with momentum storage from 0.3 mNm·s (for 1U cubesats) to several Nm·s for larger platforms.

Hyperion competes with Maryland Aerospace (MAI), CubeSpace (South Africa), Sinclair Interplanetary (Canada), and Bradford Space in the global cubesat ADCS component market — a sector that has grown dramatically with the commercial cubesat constellation boom. The company's Delft location gives it close ties to TU Delft's space engineering faculty and the Delft Aerospace Rocket Engineering student launch programs that serve as a pipeline for engineering talent.
