1394-Equipped Fault Tolerant Chipset Enables Networks
Communications Between Sensors and Spacecraft in NPOESS Program A
new series of successful tests conducted as part of an innovative
satellite program demonstrate the benefits of the IEEE 1394
standard for technologically advanced space satellite programs, the
1394 Trade Association said today. Northrop Grumman (NYSE:NOC) this
week announced that tests demonstrated that the first Fault
Tolerant 1394 integrated circuits adapted for use in space are
performing as planned. The company led the effort to verify,
qualify and manufacture the circuits for use on the next generation
of polar orbiting environmental satellites. For the satellite
application IEEE 1394a was tailored to efficiently and reliably
manage the large amounts of data that will be generated by sensors
on the National Polar-orbiting Operational Environmental Satellite
System (NPOESS) and the NPOESS Preparatory Project (NPP). Some
sensors will generate more than 30 megabits of data per second. The
1394 technology enables serial, networked communications between
spacecraft sensors and the spacecraft. It operates at speeds up to
100 megabits per second, or 100 times faster than existing
integrated circuits used in space for command and data handling.
Dave Ryan, Northrop Grumman vice president and NPOESS program
director, described the chipset as one of the most technologically
innovative aspects of the NPOESS program. The tests were performed
on NPP with the Cross-track Infrared Sounder (CrIS) engineering
development unit, using the technology at ambient (room)
temperature over several weeks at Ball Aerospace &
Technologies' facilities in Colorado. Ball Aerospace is prime
contractor for NPP, a risk reduction mission for NPOESS; Northrop
Grumman is the prime contractor for NPOESS. "The announcement from
Northrop Grumman Corporation is the latest in a growing series of
successes for 1394 in some very exciting and valuable
applications," said James Snider, executive director of the 1394
Trade Association. "Their testing program for the polar orbiting
satellite system demonstrates the benefits of 1394. These include
very high speed data transport, peer-to-peer connectivity which
eliminates the need for a central controlling host, flexible
topology which makes it easy to add devices on an as needed basis,
and efficient allocation of bandwidth which benefits configurations
which include a variety of devices with varying throughput needs.
These are the attributes of 1394 that continue to move it into new
product groups, and we are very pleased to hear of their
application in the fault-tolerant chipset for the satellite
program." Snider added that the recent announcement contributes to
a growing set of leading edge space and military applications in
which 1394 has played a major role, beginning back in the mid-1990s
with the advent of the Joint Strike Fighter program, among others.
