Integral Systems, Inc., (Nasdaq:ISYS) announced today that it has received an Authorization to Proceed from Orbital Sciences Corporation (NYSE:ORB – News) to provide the major ground segment elements for the MEXSAT-3 satellite program. MEXSAT-3 is being built by Orbital for Boeing Space &Intelligence Systems as a part of a three-satellite, turnkey geomobile satellite system awarded to Boeing in December. An Orbital STAR2 satellite will provide the complete Fixed Satellite Services (FSS) of the MEXSAT satellite system for the Federal Government of Mexico.

To support MEXSAT-3, Integral Systems will provide primary and backup satellite control centers incorporating its industry leading EPOCH Integrated Product Suite (IPS), as well as executable satellite procedures and displays. Integral Systems will also provide primary and backup Telemetry, Tracking and Control (TT&C) stations located in Mexico, and deliver its COMPASS(TM) Network Management System (NMS) from Newpoint Technologies, a wholly-owned subsidiary of Integral Systems. A turnkey carrier monitoring and frequency planning system based on the Monics(R) Carrier Monitoring and Interference Detection solution from SAT Corporation, also a wholly-owned subsidiary of Integral Systems, will be installed at two locations in Mexico. Integral Systems Europe (ISE), a wholly-owned subsidiary of Integral Systems, will provide all antenna and radio frequency aspects of the ground segment.

“Orbital is pleased to contract with Integral Systems to support the ground segment that will serve MEXSAT-3, and looks forward to providing the end user, SCT, with a product that allows them to maximize their goals and objectives through an established teaming relationship that combines the best of Orbital and Integral Systems,” said William Cook, Orbital’s MEXSAT Program Director.

Integral Systems’ commercial clients using EPOCH IPS include the Broadcasting Satellite System Corporation (B-SAT), SKY Perfect JSAT, AsiaSat, KT Corporation, Vietnam Posts and Telecommunications Group (VNPT), Indovision, SingTel/Optus, Intelsat, SES, Telesat, EchoStar and Hellas Sat, while government clients include the National Space Organization of Taiwan, European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), NASA, the U.S. Air Force and the National Oceanic and Atmospheric Administration (NOAA) among many others.

“Our long-standing partnership with Orbital will provide the MEXSAT-3 program with an efficient and cost-effective satellite ground system in a fraction of the deployment time commonly required,” said Mark Schmitt, Vice President of American Operations at Integral Systems. “The combination of EPOCH IPS, COMPASS and Monics brings the power of three industry-leading, commercial-based command and control, equipment monitoring and interference monitoring and detection systems together to support the MEXSAT program’s needs now and in the future.”
