RT Logic Provides Systems to Raytheon for NPOESS C(3) Segment

COLORADO SPRINGS, Colo., Feb. 15/Satnews Daily/ — RT Logic, a wholly owned subsidiary of Integral Systems, Inc. (NASDAQ:ISYS), announced on Monday the delivery of multiple satellite ground products to Raytheon for the National Polar-orbiting Operational Environment Satellite System (NPOESS) Command, Control, and Communications Segment.

Raytheon's Intelligence and Information Systems in Aurora, Colorado is providing the NPOESS ground system, including the Command, Control, and Communications Segment (C(3)S). The C(3) Segment manages the overall mission, including active operation and accounting of mission data, delivery of sensor data for further processing, and satellite command and control. RT Logic said it is delivering six Payload Pre-Processor Systems and five Telemetry and Command Modems.

RT Logic said the NPOESS Preparatory Project (NPP) Payload Pre-Processor (PPP) Systems use the company’s Telemetrix 500GT Gateway product to process the NPP payload downlink at rates up to 350 Mbps. RT Logic's Telemetrix software and High Rate Digital Front-end Processor are combined on the T500GT's realtime Linux server platform to perform digital data acquisition, frame synchronization, derandomization, Reed Solomon decoding, CCSDS processing, and data archival to an integrated RAID-5 storage system.

The T70/70XL modems are being installed at NASA's Satellite Ground Station (SGS) in Svalbard, Norway to process the low rate command, control, and mission data for NPOESS related missions, such as the NPP satellite. NPOESS and NPP communicate either through NASA's TDRSS satellite or directly to the ground. Both links employ the TDRSS satellite's unique spread spectrum modulation and demodulation techniques, and the T70/70XL processes the spread spectrum signals.

Jerry Meleski, director of RT Logic's Control Center Systems group, said the inherent programmability of the Telemetrix systems enables Raytheon's solution to fully meet current and future mission requirements.
