What is MIL-STD-1553 All About?
A Look at MIL-STD-1553
Following the standard is everything in the world of avionics. In the industries that uses serial data buses, MIL-STD-1553 is recognized across the board as the standard. Infect, it is 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. In addition, even NATO has adopted this standard. Well, What is actually the main purpose for the standard? The purpose of the standard is 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 large and complicated system that relays information. Reliability is probably the main reason that this standard has endured and expanded since its initial use more than four decades ago. 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 infect been published since 1978.
The Main Qualities of MIL-STD-1553
There are many reasons why this standard has gained so much attraction 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 release to the public 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 most 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.
