If It Ain’t Broke

Customers regularly ask me why aircraft still use MIL-STD-1553 for their communications infrastructure, rather than a significantly more modern technology like Ethernet? Here’s some of what I can tell them. Way back in what now seems a little like pre-history, MIL-STD-1553 was studied by an aerospace industry group in the early stages of standardization of aircraft interfaces. They spent many years reviewing it. They analyzed it. They tested it...

Designing for MIL-STD-1553

When a technology is architected to be robust, and has proven to be so in countless deployments over tens of years, it can be very easy to take it for granted. A prime example is MIL-STD-1553B. It just works, right? Well: yes and no. In theory, you buy the right parts, drop them on to a PCB, write some software — and you’re good to go. After all: the 1553 standard is designed to deal with a host of signal integrity issues — so why would you need...

Using MIL-STD-1553 to Add New Capabilities

With the phenomenal power of new sensors, and the very high performance of new processing devices, there are many new capabilities that can be added to a military system that can deliver valuable information to the war fighter and keep them safe. The latest data can be provided that can have a critical impact on the mission. But: there’s a problem. Updating an existing system to take advantage of these new capabilities isn’t a task lightly...

MIL-STD-1553: Don't Take It for Granted

MIL-STD-1553 is a very tried and true, well known, serial interface for the space and aviation industry that was originally developed for critical avionics interfaces that were required to solve the problem of connecting the many sensors and controls around an aircraft and relaying information between them and the crew. Key requirements are that information is transmitted reliably and in a timely manner. Specifically, the protocol needs to be...
