New Tests Show IEEE 1394's Successful Role in Polar-Orbiting Satellite Systems Program Led by Northrop Grumman Corporation.DALLAS -- 1394-Equipped Fault Tolerant The ability to continue non-stop when a hardware failure occurs. A fault-tolerant system is designed from the ground up for reliability by building multiples of all critical components, such as CPUs, memories, disks and power supplies into the same computer. Chipset Enables Networks Communications Between Sensors and Spacecraft in NPOESS NPOESS National Polar-Orbiting Operational Environmental Satellite System (US NOAA) Program
A new series of successful tests conducted as part of an innovative satellite program demonstrate the benefits of the IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 1394 standard for technologically advanced space satellite programs, the 1394 Trade Association said today.
Northrop Grumman Northrop Grumman Corporation (NYSE: NOC) is an aerospace and defense conglomerate that is the result of the 1994 purchase of Grumman by Northrop. The company is the third largest defense contractor for the U.S. (NYSE NYSE

Also called a "network management center" (NMC), "service management center" (SMC) or "network control center" (NCC), a NOC may be used to manage a large enterprise network, ) this week announced that tests demonstrated that the first Fault Tolerant 1394 integrated circuits Integrated circuits
Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. 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 NPP Nuclear Power Plant

The 1394 technology enables serial, networked communications between spacecraft sensors and the spacecraft. It operates at speeds up to 100 megabits per second (unit) megabits per second - (Mbps, Mb/s) Millions of bits per second. A unit of data rate. 1 Mb/s = 1,000,000 bits per second (not 1,048,576).
E.g. Ethernet can carry 10 Mbps. , 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 as needed prn. See prn order. 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 The Joint Strike Fighter (JSF) became synonymous with the later F-35 Lightning II, however until 2001 the term was applied to the competition between the Boeing X-32 and Lockheed Martin X-35. , among others.
