Integral Systems Successfully Deploys Industry-leading Carrier Monitoring, Interference Detection and Spectrum Scheduling System

Integral Systems, Inc., (Nasdaq:ISYS) announced today at the CommunicAsia 2011 exhibition and conference in Singapore, that its wholly-owned subsidiary, SAT Corporation, has successfully completed installation of a fully integrated carrier monitoring, satellite interference detection and spectrum scheduling system for MEASAT Satellite Systems ("MEASAT").

SAT Corporation provided its industry-leading Monics® satellite signal interference monitoring, detection and analysis system at MEASAT Teleport and Broadcast Centre (MTBC), located in the outskirts of Kuala Lumpur. Monics gives MEASAT the ability to monitor payload traffic, and detect and analyze Radio Frequency (RF) interference, even if the interference is within the main carrier.

In addition, SAT Corporation deployed Foresight from its strategic partner, Clearbox Systems. The combination of Monics with Foresight gives MEASAT the ability to fully manage transponder traffic and to monitor, detect and analyze RF interference. MEASAT will also be able to manage transponder space by adding customer transponder leases and carriers to the database in real time.

Using SAT Corporation's Digital Signal Processing (DSP) technology, Monics with SAT-DSP is a state-of-the-art RF monitoring system providing automatic carrier monitoring, and interference detection and analysis of MEASAT's entire constellation of satellites. Monics' unique algorithms automatically detect, characterize and display interfering signals, and allow results to be viewed at any time.

Foresight is a satellite spectrum scheduling tool for satellite operators and satellite users. When integrated with Monics, users are able to schedule carrier access, populate Monics databases and view in real-time tabulated carrier measurement parameters and graph trends by transponder. Foresight also integrates with COMPASS™ Network Management System (NMS) from Newpoint Technologies, a wholly-owned subsidiary of Integral Systems. Foresight with COMPASS optimizes workflow for carrier site construction and tear down.

Integral Systems and its family of companies – including SAT Corporation and Newpoint Technologies – will be exhibiting at CommunicAsia 2011, being held June 21 through 24 at the Marina Bay Sands Convention Center, Marina Bay Sands, Singapore.
