Integral Systems, Inc. today announced that Madrid, Spain-based GMV has awarded the
company a contract to provide the primary and backup control systems for the
SPAINSAT satellite. This satellite is being procured by HISDESAT from Space
Systems/Loral (SS/L), Palo Alto, Calif., and will be operated by HISDESAT.

The SPAINSAT Satellite control system will incorporate several elements of
Integral Systems’ EPOCH 2000 product line, including the EPOCH 2000 command
and control software and the TRECS (Transponder Reconfiguration System)
payload reconfiguration software. TRECS is a recent addition to the Integral
Systems product line, which was first introduced in 1992 as the world’s first
Commercial Off-The-Shelf (COTS) command and control software suite for
satellite and fleet operators.

The SPAINSAT Control Software will be built in close cooperation between
the European subsidiary of Integral Systems and GMV, S.A.

“While this is Integral Systems’ first satellite control system delivery
to HISDESAT and our first contract in Spain, our subsidiary, SAT Corporation,
has had a long-standing relationship with HISPASAT, the HISDESAT major
shareholder. We are very pleased to be working with HISDESAT on this program
and to expand our corporate relationship with them to include our command and
control products,” said Stuart Daughtridge, Vice President of the Commercial
Division at Integral Systems.

“We are extremely pleased by this new contract in Europe, and we are
looking forward to working in close cooperation with GMV and SS/L to satisfy
HISDESAT,” explained Bruno Dupas, President of Integral Systems Europe S.A.S.

our ability to work with local partners.”
