The Standard in Mission-Critical Connectivity

Real-time Aerospace and Defense applications must employ a modular open systems architecture to:

  • Minimize integration, maintenance and upgrade costs,
  • Foster reuse and
  • Enable rapid reconfiguration to meet evolving mission requirements.

With its interoperability, portability, loose coupling and real-time Quality of Service (QoS), the Data Distribution Service (DDS™) is the predominant standard for implementing mission-critical open architecture systems.

As the leading DDS solution, RTI Connext provides the proven and most productive environment for developing DDS compliant systems. Its broad support for programming languages, operating systems, processor architecture and network types make it ideally suited to integrate everything from sensors at the edge, to track management in the cloud.
