Integral Systems Integrates Its Industry-Leading Programmable Telemetry Processors Into Its Telemetrix Series of Products Offere

Integral Systems, Inc., (Nasdaq:ISYS) announced today that it plans to combine the development for two of its flagship product lines into the Satellite Ground Systems division of RT Logic, a wholly-owned subsidiary of Integral Systems. The products include the front-end processor and test capabilities of the RT Logic Telemetrix-500 (T500) series and the Avtec Programmable Telemetry Processors (PTP), offered by Integral Systems' SATCOM Solutions Division. Combined, the product lines support an overwhelming majority of the worldwide civil, defense and commercial space programs for test and operations.

"Integrating with the team at RT Logic is a natural progression for the PTP product," said Brian Safigan, PTP Product Manager for RT Logic. "As we move forward with co-development and integration initiatives, the new Telemetrix PTP product will provide even greater benefits and flexibility for customers who need reliable payload and communications testing. We are committed to providing our customers with the unparalleled support they've come to expect from the PTP product line."

The T500 series of products are found at the heart of USAF, Intelligence, DoD and civil satellite control networks and provide industry-leading support for secure missions requiring encrypted communications front-end processing, networking and recording. The products are also widely deployed in factory/payload test and launch operations.

The PTP product line is extensively deployed in NASA, NOAA, commercial and university-based centers. Integral Systems' PTPs are well known for configuration flexibility, as well as for powerful payload and communications testing. The T500 and PTP products support the industry's most stringent standards, including CCSDS, SGLS and other related standards.

"We are committed to providing continuous and long-term support for all customers who use the T500 or PTP products," said Mike Rice, Vice President for Satellite Ground Systems Products, RT Logic. "Our customers will also benefit from our intent to jointly engineer the next generation of products."

Last year, Integral Systems acquired CVG Inc. and Avtec Systems, Inc., which now operate as Integral Systems' SATCOM Solutions division.
