RT Logic Awarded South Pole TDRSS Relay II Project by LJT & Associates, Inc.

RT Logic's Telemetrix Products Featured throughout the Ground Architecture

COLORADO SPRINGS, Colo., July 23 /PRNewswire-FirstCall/ -- RT Logic, a
wholly owned subsidiary of Integral Systems, Inc. (Nasdaq: ISYS), today
announced 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). Scheduled delivery is mid-August, 2008.
Under the SPTR II upgrade effort RT Logic will supply several products
including the Telemetrix 1200HDR (T1200HDR) high data rate modem, the
Telemetrix 400XR modem, and the Telemetrix 500HR (T500HR) high rate front-end
processor (FEP).
High rate file transfers will be enabled by RT Logic's T1200HDR modem and
T500HR FEP interfacing to NASA's Tracking and Data Relay Satellite System
(TDRSS) Ku-Band Single Access Return (KuSAR) high rate link. These RT Logic
products will combine to enable the relay of science data via file transfers
at rates up to 300 Mbps.
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.
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.
"We are very pleased to be working with LJT & Associates on an important
TDRSS program." said Matt Langenbahn, RT Logic's SPTR II Project program
manager, "Our goal is to make LTJ & Associates successful by leveraging our
extensive experience with TDRSS ground instrumentation solutions. Also, with
our solution being based on proven, off-the-shelf products with quick lead
times, we can meet LJT's demanding delivery/travel schedules for their planned
installations at the South Pole."
"The South Pole is a very unique environment with an ever increasing
requirement for science data transmission to CONUS. RT Logic's flexible,
reconfigurable, and high data rate architectures will serve as a common
platform to support the growing needs of the diverse South Pole science
community well into the future." said Julio Varela, LJT & Associates, Inc.
SPTR II Program Manager, "LJT was pleased to select RT Logic as a critical
partner in this effort. The expertise and quality demonstrated by RT Logic
will make this program a success."
