Deployable Reflectors

Large Space Structures offers a wide range of high precision reflectors. Varying from Deployable, Shaped Deployable to Reconfigurable Reflectors. Click on the entries below to learn more about our products.

Deployable Reflectors

LSS offers deployable antenna reflectors with aperture diameters ranging from 0.5 m to 35 m and above, using different concepts for the deployable backing structure such as umbrella and peripheral ring architectures. The deployable reflectors can be fitted with a broad range of reflecting surface materials / concepts from the FlexRS® technology and can be used for frequencies up to Ka-band, depending on the category. The following categories are available:

  • Small Deployable Reflectors: 0.5 m – 4.0 m
  • Medium Deployable Reflectors: 4.0 m – 8.0 m
  • Large Deployable Reflectors: 8.0 m – 18.0 m
  • Very Large Deployable Reflectors: 18.0 m – 35.0 m

Shaped deployable reflectors are in active development. They combine the advantages of mesh-based deployable reflectors with the capabilities of radiation pattern contouring.

LSS and Thales Alenia Space are working on in-orbit reconfigurable antenna reflectors. LSS supplies the reconfigurable reflecting surface including the interfaces to the actuators. The reconfigurable surface material (FlexRS® Category III) is suitable for frequencies up to Ka-band and can be tailored to provide the desired mechanical properties according to the requirements of the customer.

FlexRS® Product Range

With the FlexRS® product range, Large Space Structures is offering reflecting surfaces in three categories. From very thin and flexile shell structures to pre-stressed metal meshes and flexible shells with increased stiffness the FlexRS® product range offers highes durability for space exploration.

FlexRS® Category I: Flexible Reflecting Shell Membranes

FlexRS® Category I surfaces are very thin and flexible shell structures, which show aspects of membrane as well as shell behavior. They are therefore called Shell Membranes.

  • Tailorable material properties
  • Used in combination with supporting structures
  • Applicable frequencies: up to Ka-band
  • Functionalization possibility (e.g. RF-active coatings, coloring)

Category II surfaces are based on pre-stressed metal meshes, which are typically supported by a cable network or ribs for providing the reflector’s contour.

  • Applicable frequencies: currently up to Ku-band
  • Grating Lobe Reduction possibility
  • Shaping of category II surfaces in development

Category III surfaces are flexible shells with increased stiffness compared to Category I surfaces, while maintaining high deformability and foldability. These surfaces can fully deploy and maintain their shape under microgravity conditions. This enables the creation of deployable reflectors with greatly reduced need for support structures.

  • Applicable frequencies: up to Ka-band
