SpaceTech GmbH

SpaceTech GmbH (STI) is an independent German medium-sized space company founded in 2004 by Bernhard Doll and Jost Munder, headquartered in Immenstaad on Lake Constance in southern Germany. Starting from just two founders, the company has grown into an internationally recognised supplier of space equipment, with more than 1,500 STI instruments and units currently operating in orbit.

STI's business rests on four pillars: solar arrays (including multi-hinge deployable solar array wings, deployment mechanisms and in-house photovoltaic assembly production), optical/laser instruments (high-stability lasers, laser ranging interferometers and frequency reference units for Earth observation and fundamental science), satellite electronics (laser head electronics, digital and data handling units, actuator drive units) and structures/mechanisms and sensors (including the Coarse Earth and Sun Sensor, CESS).

The company has contributed hardware and subsystems to numerous institutional and commercial missions, including FormoSat-5, KompSat-3, GökTürk-2, GRACE Follow-On, MERLIN, JUICE (RIME antenna), Sentinel-5 (UVNS Calibration Subsystem), EUCLID, PLATO, and large-scale solar array production for the Airbus OneWeb Satellites mega-constellation (1,800 solar array deployment mechanisms). SpaceTech's customers include ESA, DLR, Airbus, CNES and other space agencies and commercial space companies worldwide.

SpaceTech is ISO 9001 and ISO 14001 certified and operates its own clean rooms, test facilities (thermal-vacuum and shaker) and CNC manufacturing at its Immenstaad headquarters, along with its subsidiary CarboSpaceTech for CFRP composite structures.
