Abstract: The smart canister systems disclosed herein enables missile population to increase while minimizing the need for additional interface hardware. Particularly, multiplexing and demultiplexing functions and conversion flexibility enable the system to be adaptable to different types of missile characteristics and hardware. A redundant, bi-directional bus architecture with a distributed and dynamically reconfigurable control as well as enhanced built-in-test, fault monitoring and display capability enable the smart canister systems to provide a faster response time and higher launcher availability in a multifarious missile environment.
