The whole concept of 1553 mil std is that it is a standard set by the military. The United States Department of Defense works to define and set standards for a serial data bus. The serial data bus can be put to use for varying functional items including mechanical as well as electrical functions.
The history of 1553 mil std dates back to avionics. The first purpose for it was military avionics, as it would act as a standard for the avionic data bus. The evolution of it over the past years though has had it spreading as a standard for other purposes as well. Spacecraft onboard data handling subsystems is a great example of where the evolution has come in.
So what exactly makes up a data bus system with the standard of 1553 mil std? It is a whole system that includes a Bus Controller (BC) working to control many different Remote Terminals or (RT). The data bus then works to bring all of these together. One singular data route is then put in place to bring the data from the Bus Controller to the Remote Terminals one at a time.
There are a lot of great uses for this type of technology. Sital Tech, for example, has a hardware chipset meeting the standard which helps with in-vehicle wired network communications. In the event there is any type of physical circuit failure or malicious cyber attack, it will work to detect it immediately.
Real-time detection is important when talking about cyber-attacks and circuit failures. If you have a vehicle, an airplane, spacecraft, or something else, there is a lot of technology in there now. The potential exists that a cyber-attack could bring any of these systems down, posing a lot of risks and potential harm. With the data bus standard met and a Sital chipset in place, you will have real-time detection. Real-time detection is a great way to ward off any potential threat or risk.
The 1553 mil std is not new as it has been around for years. It dates back originally to the 1970s, but it continues to evolve as the years go by and the technology gains in advancement. When you have a data bus system that meets this standard, it provides a higher sense of security than others. You can be confident in the data transfer, know that it will be fast, secure, and complete. When it comes to managing data and making sure your avionics systems function as intended, there is not much more you can ask for.
