RT Logic, a wholly owned subsidiary of Integral Systems, Inc. (NASDAQ: ISYS), has received a contract award by LJT & Associates, Inc. (LJT Inc.) for the South Pole TDRSS Relay II Project (SPTR II). LJT & Associates, Inc. is a prime contractor for the National Science Foundation (NSF) and SPAWAR upgrade of Amundsen-Scott South Pole Station data relay link to the White Sands Complex (WSC). The SPTR II award is just one of a number of RT Logic’s TDRSS related efforts. RT Logic has recently demonstrated systems to NASA for the TDRSS K-Band Upgrade (TKUP). RT Logic’s T1200HDR supported data transfer over the KSAR link at rates up to 1.2 Gbps.Scheduled delivery is mid-August, 2008. Under the SPTR II upgrade effort, RT Logic will supply several products:
- The Telemetrix 1200HDR (T1200HDR) high data rate modem
- The Telemetrix 400XR modem
- The Telemetrix 500HR (T500HR) high rate front-end processor (FEP)
The T1200HDR is RT Logic’s latest Wideband Modem product. It employs digital receiver technology to meet multi-mission, high data rate requirements. The T1200HDR supports most of the popular demodulation schemes (BPSK, QPSK, SQPSK, and optional UQPSK and 8PSK signals). Data rates up to 1.5 Gbps are supported. The RT Logic T500HR is RT Logic’s high rate digital data processor and capable of ingesting and processing multiple, concurrent, real-time data streams at aggregate data rates to 1.6 Gbps. The T500HR performs frame synchronization, forward error correction, data filtering/sorting, PCM simulation, IRIG time-tagging, and network data distribution for ingested TDM and CCSDS data. The T400XR is a modular, firmware defined modulator, receiver, and digital processing unit. With firmware-defined waveform processing, the T400XR can be used as a replacement for legacy receiver models or for new applications. Multi-channel systems support diversity combining or multiple simultaneous downlinks and uplinks.
