Integral Systems, Inc.
today announced a contract with Lockheed Martin Commercial
Space Systems (LMCSS) that expanded Integral’s existing JCSAT-9 satellite
control system contract to include the JCSAT-10 satellite. LMCSS was able to
take advantage of EPOCH’S flexible design to offer a low-cost, no-risk
solution for the JCSAT-10 satellite control system that will be fully
integrated with the JCSAT-9 system.

The system will incorporate several elements of Integral Systems’ EPOCH
IPS (integrated product suite) product line to provide complete real-time
command and control system as well as automated scheduling, procedure
execution, offline trending and analysis functions, and flight dynamics. In
addition, LMCSS has selected Integral’s Status and Control (S&C) System for
monitoring and controlling the JCSAT-10 ground station antenna and RF
equipment. The S&C System will be provided through Integral’s Newpoint

Technology division of Salem, NH, and will be based on the COMPASS product.
“We are pleased to expand our relationship with both Lockheed Martin, one
of the world’s premiere satellite manufacturing companies, and with JSAT
Corporation, the largest satellite operator in the Asia-Pacific region,” said
Stuart Daughtridge, Vice President of the Commercial Division at Integral
Systems. “Our proven EPOCH system provides LMCSS and JSAT a state of the art,
integrated solution that meets the combined requirements for the JCSAT-9 and
10 programs and gives JSAT a consolidated satellite control solution for the
operations of these and future satellites,” he added.

Integral Systems also has supplied satellite ground systems to NASA
(National Aeronautics and Space Administration), NOAA (National Oceanic and
Atmospheric Administration), the U.S. Air Force, the U.S. Navy, the Johns
Hopkins University Applied Physics Laboratory, Loral Skynet, NEWskies
Satellites, Echostar, Sirius Satellite Radio, Binariang Satellite Systems,
Shin Satellite Public Company Ltd., SATMEX, GE Americom, Optus, ChinaSat,
EOSAT, PanAmSat, BSAT, Alcatel, TRW, and ROCSAT (Republic of China) among
others.
