How Mil-std-1553 Began?

Standards are an important facet in any large scale operation where a lack of protocol could result in compromised results or outright failure. The US military is based on a system of standards to keep all of the separate units functioning as one while maintaining an optimum level of efficiency. The MIL-STD-1773 is a perfect example of this code of conduct.

A system of standards was needed to document and identify the needs for data bus informational transfers between various types of military crafts and terminals. Definitions were needed for the electrical, mechanical and also the functions that were to be used in all military communications hardware. There is a critical need for uniformity in the design of the subsystems to keep the hardware running the way it is intended. Without a standardized system to rely on, communication processes could become vulnerable. The MIL-STD-1553 was the initial standard released by the United States Department of Defense. When optical cabling was proved to be more stable than electrical wiring they updated the standard to MIL-STD-1773.

This standard paved the way for a process that could communicate with several different terminals. The large amounts of data created from a complex communications and navigational system needed a specialized process that could offer constant bandwidth. This task was accomplished by utilizing the principles behind time division multiplexing. Time-division multiplexing is a digital process where many signals are transmitted on a single channel. The results are accomplished in a near state of synchronicity but in reality, the signals are taking turns on one channel.

MIL-STD-1773 was initially conceptualized for aviation electronics to help standardize the engineering requirements for the navigation and communication systems. It was first implemented in the design and manufacture of the F-16 Fighting Falcon. The success of the project lead to MIL-STD-1773 being used in future aircraft designs such as the F-18 Hornet and the F-20 Tigershark. MIL-STD-1773 is also commonly used in onboard spacecraft subsystems as well all the other branches of the United States armed forces.

One of the aspects that has kept our military forces successful on a global scale is the emphasis that is placed upon organization. Organized forces have historically held significant advantages over a scattered opponent. The system of standards and protocols employed by our armed services has always adhered to a logical hierarchy. Every component has a place and nothing operates outside the established order. To bring about change in this rigid system of military order is not an easy thing to accomplish. But sometimes, change is inevitable. As the world leaders in warfare technology, the United States military is always seeking new technologies to maintain our advantages in all areas of operation. MIL-STD-1773 is slowly being phased out to make way for a new system of standards that are being developed by the United States military with help from the company FireWire. Not much is currently known about the new implementations but the standards will be based on the IEEE 1394 interface which is used to transfer data in real time and is also commonly used for high speed communications.
