What Is MIL-STD-1553
Category : MIL-STD-1553
A Look at MIL-STD-1553
Following the standard is everything in the world of avionics. In an industries that use serial data buses, MIL-STD-1553 is recognized across the board as the standard. It is actually a military standard that is published by the United States Department of Defense. After being established in 1973 for fighter aircraft, the standard quickly expanded to cover mainstream use for both military and civil operations. What’s more, even NATO has adopted this standard. What is the main purpose for the standard? It is used to define the mechanical, electrical and functional characteristics of a serial data bus. If you’ve ever worked with the standard, you already know that it is a pivotal piece in a la
rge and complicated system that relays information. Reliability is really the main reason why this standard has endured and expanded since its initial use more than four decades ago. What does all of this mean for a person working in the avionics industry? It is important for companies in the avionics world to have access to products that are compliant with MIL-STD-1553. In addition, the ability to stay current with updates and changes to the standard is pivotal. Six change notices to the standard have actually been published since 1978.
The Main Qualities of MIL-STD-1553
There are many reasons why this standard has gained so much traction in the avionics world. It certainly helps to create a uniform, reliable system for companies that work on the various aspects of data buses. The main goal of the system is to relay information using automated data transfers between devices and sensors. This standard also introduced the concept of optional broadcast transfers to the world. Some of the important things to know about MIL-STD-1553 are:
- It features multiple redundant balanced line physical layers, network interface, time division multiplexing and half-duplex command and response protocol.
- It can handle up to 30 remote terminals.
- There is a version that uses optical cabling in place of electrical cabling that is called MIL-STD-1773.
- It is maintained by the United States Department of Defense and the aerospace branch of the Society of Automotive Engineers.
