A thorough understanding of  details of  satellite equipments and "hands-on" experience in development, manufacturing, assembly, integration and test is an ideal foundation for the development of higher levels of integration as in subsystems. SpaceTech develops selected satellite equipments, both for use in our own subsystems and as self standing products, making extensive use of our in-house manufacturing and test capabilties..

Our equipment product range includes in particular:
  • Deployment mechanims
  • Refocus mechanisms
  • Reaction wheel dampers
  • Coarse Earth Sun Sensors (CESS)

The design, manufacturing, qualification and delivery of these equipments are an important complement to our system and subsystem activities. With Kompsat 3 and Göktürk-2 deployment mechanisms successfully deployed in orbit,  as well as the production of CESS safe mode sensor in exclusive licence to Airbus DS, SpaceTech acquired significant space heritage in this field.


Recent examples of our projects in this field are:
