Integral Systems Group Shares NASA ‘Software of the Year’ Award

Simulation Software Advances Propulsion Technology

An Integral Systems, Inc. team
supporting NASA Glenn Research Center, Cleveland, Ohio, is part of a group
that was selected co-winner of NASA’s Software of the Year Award 2001.
The
Integral team has been working for two years to support Glenn’s Numerical
Propulsion System Simulation (NPSS), an effort that has received NASA’s
prestigious “Turning Goals Into Reality” (TGIR) award last April.

NPSS is a multi-disciplinary effort using state-of-the-art computing and
communication technology and enabling aerodynamics, structural engineering,
and heat transfer analyses.
It offers important technological advances in
designing aircraft engines, increasing safety and efficiency, and to
increasing the U.S. leadership in aerospace.
One of the industry users of the
system, the General Electric Aircraft Engines Company, has predicted a
resultant 55 percent reduction in engine analysis time.

The development of NPSS was led by Glenn with funding support from the
NASA Ames High-Performance Computing and Communications Program.
The
development team includes NASA civil servants and contractors, industry
partners, and the Department of Defense.
“Our team is honored to receive this
award.
The integrated team has proven to be essential to the success of NPSS.
NPSS Version 1 is a world-class propulsion system simulation tool that
provides a distinct competitive advantage.
Congratulations to the outstanding
members of the NPSS production team,” said Cynthia Naiman, Glenn NPSS Project
Manager.

The Integral team works under subcontract to information services provider
RS Information Systems (RSIS) and is part of Integral’s I&T (Integration and
Test) and Data Systems Division.
“We’re tremendously proud of this team.
Simulation is already critically important throughout the aerospace industry,
and this group has increased its value even further,” said Richard Isaacman,
Integral’s I&T Division Operations Director.

Founded in 1982, Integral Systems is a leading provider of satellite
ground systems and has supported over 120 different satellite missions for
communications, science, meteorological and earth resource applications.
In
addition to garnering new Integration & Test, control center, and data
processing work, the Company continues to enhance its current position in
government and commercial marketplaces by offering innovative software
products and custom services for ground system development and integration.
Customers throughout the world now use Integral Systems’ EPOCH 2000 software
product, the world’s first COTS satellite command and control software
package.
In addition to these products, the Company provides satellite
payload processing, spacecraft integration and test, simulation, station
automation, and environmental monitoring systems.
Through its wholly owned
subsidiary SAT Corporation (SAT), the Company also provides satellite and
terrestrial monitoring systems to satellite operators and users throughout the
world.
Integral Systems has more than 230 employees working at Company
headquarters in Lanham, Maryland, and at other locations in the U.S. and
Europe, including its SAT offices in Sunnyvale, California.
