TECHNICAL ACTIVITY

5.1 The satellite communication

system The consolidation of Hisdesat as one of the

principal worldwide suppliers of secure communication services

by satellite, on the military K and Ka bands, for governmental
applications, is now a reality with its range of satellite

communication systems.

The aforementioned system has as its objective to
provide communication services for applications of a
governmental nature, both civilian and military. It con-
sists of the following systems:

 SpainSat. Located at 30º West, it provides
coverage which includes practically the
entirety of the American continent, Africa
and Europe through to the Middle East.

 Xtar-Eur: Located at 29º East, it provides
coverage from Brazil through to Indonesia,
including Europe, Africa, the Middle East
and a large part of Asia. antennae have been configured in such a way that
they provide a combination of beams, both fixed and
