Thanks to the long experience in the design and development of space systems, a wide range of small satellite subsystems are designed by Sitael to satisfy the requirements of our main customers.


SITAEL power generation systems are conceived for small and low-costs satellites. Our solar array are based on space-grade Gallium arsenide (GaAs) high efficiency triple junction solar cells technology. Carbon fiber sandwich panels with Nomex® honeycomb core provide a reliable, efficient and lightweight substrate for the cells, thanks to the low coefficient of thermal expansion.



Since more than 20 years SITAEL is designing and producing electronic equipment for large space missions. Nowadays SITAEL is one of the leading companies providing innovative Earth Observation Payloads and Avionics for spacecraft and launchers.


ince the early ‘80s, SITAEL is involved in development of Electric Propulsion Systems based on innovative proprietary technologies. Electric Propulsion Products ranges from High and Low Power Hall Effect Thrusters to Electrothermal Thrusters, from micro-Newton Field Emission Electric Propulsions up to hundreds of kilowatt Magneto Plasma Dynamic Thrusters. SITAEL is today one of the few companies worldwide with development and qualification capabilities of complete Electric Propulsion systems and related diagnostics.
