MIL-1553 Training | MIL-STD-1553 Training

MIL-1553 training course by Tonex covers key MIL-STD-1553 (Including changes in MIL-STD-1553C) principles, features, protocol architecture, functional characteristics, technical components, design, operations, products, testing, cyber security and trends.  Learn about MIL-STD-1553 including MIL-1553C, the high reliable and high available communications standard used by NASA, DoD including Air Force, Navy, Army, and Marine.

MIL-STD-1553 is a military standard developed in the USA.

Originally it was used mainly in the U.S. Air Force, but today it is used by the DoD in all military sectors. It is also used in astronautics and in civil aeronautics.

MIL-STD-1553’s popularity stems from its reputation as a fast, error-free, and stable data transmission bus system. NASA, for example, has put its trust into the high level of stability of the bus and uses it in satellites and space stations. The bus is also used in civil applications such as subways where reliability is crucial.

The MIL-STD-1553 is a differential serial bus with some similarities to CAN.  Also, it is a dual redundant data bus.  Each node is connected to each of the redundant buses. It’s usability has remained high because if one data bus should fail, communications can still continue.

MIL-1553 Training Course by Tonex

MIL-STD-1553C document was released by the USAF in February 2018 as a cleaned-up version to the 1978 1553B standard. MIL-STD-1553C adds a single addition reference of MIL-STD-464. Besides this reference for system EMC specifications, 1553C = 1553B, and 1553B (or just 1553) will be used as the most common designation.

MIL-STD-1553, MIL-STD-1553, or AS15531 is a military standard, Digital Time Division Command/Response Multiplex Data Bus, published by DoD that defines the mechanical, electrical and functional characteristics of a serial data bus. It features a dual redundant balanced line physical layer, a (differential) network interface, time division multiplexing, half-duplex command/response protocol and up to 31 remote terminals (devices). MIL-STD-1773 is a version of MIL-STD-1553 using optical cabling.

Other benefits include:

Multi-Channel Coordination and Selection – In regards to modern military aircraft, it is critical that avionics systems are able to communicate discretely with one another.  This was challenging in the past, specifically when regarding the more traditional ARINC-429 architecture. However, the MIL-STD-1553 standard makes use of a bus controller.

The Exclusion of Remote Terminal Issues – Thanks to the top-down approach associated with the MIL-1553 standard all messages are preceded by a command word and are initiated only by the bus controller. This eliminates simultaneous transmissions.

Maintenance and Reliability – Thanks to designing simplifications, MIL-STD-1553 is now associated with fewer connections. Not only does this enable the systems to be much lighter (important with aircraft), but fewer connections directly equate to fewer chances of failure and greater MTBF (Mean Time Between Failure) cycles. Fewer parts are also associated with easier installation as well as the ability to upgrade such systems on a modular basis when required.

The goal of MIL-STD-1553 has always been to move data reliably. MIL-STD-1553 messages consist of up to 32 16-bit words.

There are three major components of MIL-STD-1553. The bus monitor, for example, permits the passive monitoring of the flow of data.

Another component, the bus controller, is generally part of the mission computer.

The third component, the remote terminal, could be a missile launcher or an instrument giving input to the mission computer.

Experts in this field believe MIL-STD-1553 has a bright future and that this architecture will continue to evolve as advanced generation of avionics benefit from the principles espoused by the MIL-STD-1553 protocol.
