MIL-STD-1553 was published in 1973 and it is still widely used, in aircraft designed half a century apart. Not because the industry is slow to adapt, but because the protocol fulfills its promise: predictable, deterministic timing. A command sent on a MIL-STD-1553 bus arrives within a known, bounded time, a property that significantly increases message delivery reliability in real-time systems.
1 Mbit/s may sound ancient next to modern gigabit links, but for a flight control computer predictable response and certainty take precedence.
We build the interfaces and test systems that prove avionics buses behave exactly as specified, message by message.
Testing makes you the best. Test the Best.
