Extended 1553

In March 2006, the United States Air Force and Edgewater announced an updated military standard for data bus networking in avionics. Known as MIL-STD-1553B Notice 5, the updated standard was supported by the development of Edgewater's Extended 1553 (E1553) technology which occured over a five-year period.

E1553 data bus technology enables cost-effective, incremental upgrades of aging aircraft, provides substantially improved performance across the existing 1553 data bus, and enables the functionality and capabilities required to support advanced processor, sensor and network communications.

Developed in the 1970s, the legacy 1553 data bus is the predominant LAN technology used in aircraft flown by the U.S. and Allied countries today. While many of the aircraft using 1553 have over 20 years of serviceable life left, existing 1553 technology will soon be stretched beyond its limits by the high-bandwidth requirements of future systems and applications.

For more information on Extended 1553, read our backgrounder, Edgewater's advanced data bus technology is at the forefront of next-generation intra-aircraft communications .

Edgewater's E1553 data bus technology increases data throughput capacity from 1 Mbps to an uncompressed 200 Mbps over existing aircraft wiring while maintaining a 10E-12 bit error ratio and without impact to existing, or legacy, 1553 communications.

U.S. Government personnel can obtain copies of Mil-Std-1553B Notice 5 through the Defense Document Automation and Publication Service (DAPS) ASSIST-Online service over the Internet at http://assist.daps.dla.mil/ . Canadian Government personnel, and personnel with registered U.S. and Canadian contractors, can request it from the ASC/AFRL Engineering Standards Office by submitting an email request to engineering.standards@wpafb.af.mil .
