ISYS Integral Systems, Inc. (MM)

Integral Systems, Inc., (Nasdaq:ISYS) announced today that its services organization, Integral Systems Service Solutions (IS3), has significantly increased its SATCOM NetOps service coverage by activating two additional satellite interference monitoring, detection and geolocation sites in the Republic of Cyprus and Republic of South Korea.

As part of IS3's global satellite interference monitoring, detection and geolocation network, the new facilities include dual 7.3m antenna systems, Integral Systems' industry-leading Monics® Radio Frequency (RF) interference monitoring, detection and analysis solution and its satID® geolocation system. Including the sites in Cyprus and South Korea, IS3 now supports six full-time facilities providing customers with a cost-effective RF interference mitigation capability.

"We are thrilled to reach this key milestone and to have our newest facilities up and running," said Ernie Dickens, Vice President and General Manager of Integral Systems Service Solutions. "The ability to seamlessly isolate offending carriers or provide advanced signal monitoring, detection and analysis globally is a clear differentiator for our service offering."

IS3's global infrastructure will initially support 11 full-time RF interference monitoring, detection and geolocation sites delivering unsurpassed coverage and availability. With the addition of Cyprus and South Korea, global coverage is now approximately 60 percent, expanding IS3's Interim Operating Capability (IOC) into the Middle East, Asia and Pacific Rim. Later this year, IS3 will add sites in India, Hawaii, North America's east coast, South America, Australia and Africa. When fully deployed, IS3's network of strategically placed sites will offer RF interference, monitoring, detection and geolocation service coverage on 1,127 beams from 269 commercial communications satellites – or close to 90 percent of the global Fixed Satellite Services (FSS) constellation.
