Large Deployable Reflectors (LDRs) and in orbit reconfigurable reflectors are requested by the telecommunication market more and more. High frequency applications including Ka-Band missions are required. Ka-band 5 m reflectors are requested for (very) high throughput telecommunication satellites demanding special highly stable and precise technologies. LSS GmbH is a European leader in the development of large deployable and reconfigurable antenna reflectors. LSS has demonstrated two types of LDR technologies based on its own architectures with metal mesh and shell-membrane RF surface types. In both cases, 5 m demonstrators have been designed, manufactured and tested by LSS, with some contributions from SMEs and universities, resulting into an ESA declaration of TRL 5. In addition to conventional LDR technologies, LSS is working in shaped large deployable reflectors as well as in orbit reconfigurable reflectors enabling a full coverage of the currently requested antenna reflector types. Mechanically reconfigurable reflectors can replace the typical configuration of several shaped reflectors and satellites with a single reflector and thereby allow covering newly emerging requested coverage areas on Earth during a single lifetime in orbit. Thus, their application promises huge cost savings. Further on, within an ESA project, LSS has developed a mechanical concept that can significantly reduce grating lobes for faceted surfaces of large deployable reflectors.
