TELEMETRIX 500 HIGH-RATE DATA PROCESSOR (T500HR) |
||||
| OVERVIEW |
The RT Logic Telemetrix® 500 High-Rate Data Processor (T500HR) ingests and processes multiple, concurrent,
real-time data streams at aggregate data rates to 1.6 Gbps. The T500HR performs frame synchronization, derandomization, Reed-Solomon forward
error correction, CRC error detection, data filtering/sorting, IRIG time-tagging, and network data distribution for ingested TDM and CCSDS data.
Among the T500HR options are archive, playback, network data distribution, Pragmatic General Multicast Protocol (PGM), CCSDS Space Link Extension
(SLE), rate buffering, network file management and alternate error detection/correction techniques (Low Density Parity Check (LDPC) or non-standard
Reed-Solomon). |

| APPLICATION |
Demand for wideband satellite payload data, such as Earth Observation imagery, is rapidly increasing. Earth
Observation and other wideband data processing ground stations require modular and flexible COTS solutions to support payload processing for
multiple missions. Each mission typically has requirements for high performance, real-time data acquisition, high availability, reliable data
transport, IP-based network data distribution and custom data processing algorithms. The T500HR provides a modular, tailorable, one-box solution that ingests high-rate TDM/CCSDS data, processes and stores it, and then makes it available to the network for further processing. With support for ECL, LVPECL, LVDS, RS-422, and TTL signal input/output, the T500HR readily integrates with any receiver. Software-defined algorithms enable a single T500HR to support multiple concurrent data streams per mission or to be quickly reconfigured to support alternate missions. The T500HR leverages the inherent switching power of high-speed IP networks for data distribution. Using the reliable Pragmatic General Multicast Protocol (PGM) option, the T500HR provides on-demand, reliable, efficient delivery of processed/filtered CCSDS frame/packet data to multiple users on a LAN or WAN. If the WAN is a bottleneck, the T500HR supports rate buffering to maximize throughput. |

| THE T500HR DIFFERENCE |
|
|||
| MODULAR, DIGITAL DESIGN |
The T500HR is a high-performance, real-time, high-rate digital processing system with dynamically
reconfigurable algorithms. The T500HR has a full range of firmware and software personality options for processing high-rate CCSDS/TDM
telemetry, multiplexing/demultiplexing, Time-Data Correlation (TDC), IRIG timestamping/generation, PCM simulation, derandomization, error
detection and correction (BER, Reed-Solomon, LDPC, CRC), archive, digital/analog recording, playback, and custom functions. The T500HR is a highly available server-class PC running a real-time Linux OS with hot-swappable disk drives, dual hot-swappable power supplies, Intel Xeon CPU, dual Gb Ethernet ports, RT Logic digital processor cards and ready support for today’s computer peripherals (DVD, additional NICs, 10 Gigabit Ethernet, RAID, tape drives, iSCSI, etc). It is available in 2U, or 5U configurations, and mounts in a 19-inch rack. Multiple I/O options are available including TTL, RS-422, D-ECL, LVPECL, and LVDS signal lines. Software/firmware-defined algorithms provide easy tailoring of a standard T500HR configuration to meet customer-specific requirements. Reed-Solomon decoding is performed entirely by firmware, eliminating the need for the EOL NASA Reed-Solomon chip utilized by competitor products. The system is compatible with other RT Logic products, such as the Telemetrix HDR modem, as well as third-party systems. The features and options of RT Logic’s T500GT, T500MX, and T500RX are plug-in compatible with the T500HR. |
