Messaging Communications Bus

Real-Time Innovations (Sunnyvale, CA) offers RTI Data Distribution Service, Safety-Critical Edition, a smallfootprint version of real-time messaging middleware to meet safety certification standards such as DO-178B. It is designed for communication within and between avionics systems and unmanned aircraft system (UAS) ground control stations. It provides a message bus for integrating distributed components of avionics systems such as control systems, sensors, actuators, and displays. It allows individual subsystems to be added or upgraded without impacting existing software.

The Safety-Critical Edition supports the standard DDS interoperability protocol and the Real- Time Publish-Subscribe Protocol (RTPS). Applications developed using the middleware can seamlessly communicate with other systems developed using RTPS-compliant DDS middleware. This allows military UASs to be integrated with net-centric combat systems.
