COLORADO SPRINGS, Colo., 14 February 2005. RT Logic, a wholly owned subsidiary of Integral Systems, Inc., today announced 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, Colo. 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 is delivering six payload pre-processor systems and five telemetry and command modems.
The NPOESS Preparatory Project (NPP) Payload Pre-Processor (PPP) Systems use RT Logic's Telemetrix 500GT (T500GT) 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 (including VCID and APID sorting), and data archival to an integrated RAID-5 storage system.
During an NPP contact, the T500GT acquires, processes, sorts and archives data, while simultaneously rate buffering the same data over a reduced rate TCP/IP WAN for ingest by data processing applications. Between contacts, archived data files are made available to external post-processing applications for on demand data access.
The Telemetry and Command Modems are RT Logic's Telemetrix 70/70XL (T70/70XL) product. Software-defined signal processing functions are performed within the T70/70XL via FPGA-based firmware personalities, allowing the unit to support NPP, NPOESS, and future missions. The T70/70XL is configurable to support the full spectrum of IF/ baseband processing, signal modulation/demodulation, and digital front-end functions for satellite telemetry, command and ranging links.
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.
"We are pleased to support Raytheon on the NPOESS and NPP programs," said Jerry Meleski, director of RT Logic's Control Center Systems group. "The inherent programmability of the Telemetrix systems enables Raytheon's solution to fully meet current and future mission requirements."
RT Logic is a leading provider of products for ground-based space applications, primarily for satellite and launch range operations. Known for exceptional innovation, performance and support, RT Logic has delivered over 1200 systems since its inception in 1997. RT Logic offers a complete line of Telemetrix products used in systems for widely varied control center, ground antenna, and range applications. Since October 2002, RT Logic has operated as a wholly owned subsidiary of Integral Systems Inc.
Founded in 1982, Integral Systems is a leading provider of satellite ground systems and has supported over 190 different satellite missions for communications, science, meteorological, and earth resource applications. The Company was the first to offer an integrated suite of COTS (commercial off the shelf) software products for satellite command and control, the EPOCH IPS product line. EPOCH has become a world market leader in commercial applications with successful installations on five continents. The company also offers products and services for satellite integration and test and payload data processing as well as a full motion tracking antennas.
The company's subsidiary, SAT Corp., provides satellite and terrestrial communications signal monitoring systems to satellite operators and users throughout the world. Through its Newpoint Technologies, Inc. subsidiary, the company also provides software for equipment monitoring and control to satellite operators and telecommunications firms. Integral Systems has approximately 360 employees working at company headquarters in Lanham, Md., and at other locations in both the U.S. and Europe.
