Integral Systems Announces the Only In-Service In-Orbit Test System That Analyzes Operational Transponders With No Impact to Ongoing Satellite or Communication Network Operations

WASHINGTON and SUNNYVALE, Calif., March 15, 2011 (GLOBE NEWSWIRE) -- Integral Systems, Inc., (Nasdaq:ISYS) announced today at the SATELLITE 2011 Conference that its wholly-owned subsidiary, SAT Corporation, has developed technology that will significantly change the way satellite operators and manufacturers test and run their satellite networks. Monics® Advanced In-service In-orbit Test (IOT) system uses advanced measurement techniques to characterize the transponder in terms of gain, frequency response and phase, even while the transponder is operating. As the market's only true In-service IOT solution, Monics Advanced In-service IOT does not impact revenue-generating traffic while performing network data stream analysis or characterizing transponder performance.

WASHINGTON and SUNNYVALE, Calif., March 15, 2011 (GLOBE NEWSWIRE) -- Integral Systems, Inc., (Nasdaq:ISYS) announced today at the SATELLITE 2011 Conference that its wholly-owned subsidiary, SAT Corporation, has developed technology that will significantly change the way satellite operators and manufacturers test and run their satellite networks. Monics® Advanced In-service In-orbit Test (IOT) system uses advanced measurement techniques to characterize the transponder in terms of gain, frequency response and phase, even while the transponder is operating. As the market's only true In-service IOT solution, Monics Advanced In-service IOT does not impact revenue-generating traffic while performing network data stream analysis or characterizing transponder performance.

To reduce transponder compression risks, satellite operators will often run their systems at less than peak performance – sometimes at 50 percent less than optimum. With Monics Advanced In-service IOT, users can conduct tests in real-time in a fraction of the time current IOT systems require – all accomplished without having to remove critical bandwidth from the transponder. This provides the added benefit of pushing the network to optimal performance levels. The significant increase in efficiency results in reduced costs, enhanced Service Level Agreement (SLA) enforcement, increased Quality of Service (QoS) and maximized power and bandwidth use.

In addition, Monics Advanced In-service IOT maximizes the revenue generating potential of a satellite immediately after launch. The system's exceptionally fast measurement speed significantly reduces test times, which allows the satellite to enter service faster upon reaching orbit.

"Monics Advanced In-service IOT represents a major shift in transponder testing and will become the de facto standard for satellite operators and manufacturers looking to significantly reduce costs, increase margins and maximize efficiency," said Bob Potter, President of SAT Corporation. "Our innovative advanced measurement techniques passively test in real-time without disrupting revenue-generating network traffic."

The Integral Systems family of solution providers, including SAT Corporation, will be exhibiting at the SATELLITE 2011 Conference taking place at the Walter E. Washington Convention Center in Washington D.C., March 15 through 17. Please visit booth #557 for more information.
