SICRAL 1, 1B

SICRAL 1 [Alenia]

SICRAL (Sistema Italiana de Communicazione Riservente Allarmi), the first national italian system for satellite military telecommunications, has been developed by the SITAB consortium made up of Alenia Spazio, a Finmeccanica Company (70%), Fiat Avio (20%) and Telespazio (10%).

The SICRAL 1 satellite can operate simultaneously on several frequency bands (SHF, EHF and UHF), a characteristics first in Europe, with the possibility to switch the bands on-board of the satellite (first in the world). The UHF satellite repeater is the Europe's most powerful and the only one to operate inter-connected to the SHF/EHF band.

The contract for SICRAL 1B was signed in late 2006.
