About
SpaceTech offers a one-stop solution for the full scope of solar arrays: body-mounted panels, single-hinge deployable arrays, and multi-hinge deployable solar array wings, including deployment electronics, hold-down and release mechanisms (HDRM), solar array drive mechanisms, as well as photovoltaic assemblies on panels. Production is highly automated yet flexible, using in-house panel manufacturing and photovoltaic cell laydown together with SpaceTech’s unique deployment mechanisms. Over the last years, SpaceTech has developed a novel multi-hinge deployment mechanism technology suitable for a wide range of solar array sizes, from less than 0.5 square meters (XS) to more than 6 square meters (XL) per panel, featuring controlled, unsynchronized deployment using C-spring hinges of standardized sizes. SpaceTech serves both NewSpace mega-constellations and the most demanding institutional missions; examples of its solar array activities include the Airbus OneWeb Satellites constellation, York Space Systems, GökTürk-2, Sentinel-5P, Sentinel-6, EUCLID, CHIME, CO2M, CRISTAL, LSTM and PLATO.
