Next-Generation Distributed Maritime Systems

Building autonomous maritime systems is incredibly challenging due to the ever-changing environment and adversarial threats. Undersea systems have additional challenges as they submerge and lose communications.

To help meet these challenges, the U.S. Navy has developed the Unmanned Maritime Autonomy Architecture (UMAA) to define a comprehensive data model and a standardized group of services required of maritime vessels and systems. This data model and the required services connect via a common connectivity framework, based on the Data Distribution Service (DDS™) standard.

RTI Connext implements the UMAA Autonomy Bus as defined in the UMAA Architecture Document, and provides fast, scalable, reliable, and secure connectivity for on- and off-vehicle communications in real time. Through its integration with UMAA-based designs, Connext enables rapid system updates and mission readiness, while driving down system maintenance costs.



RTI Connext drives UMAA mission success by:

  • Ensuring that sensor and command data are delivered in real-time when and where needed
  • Providing real-time communication within the vehicle, off-vehicle and between vehicles
  • Ensuring data confidentiality and integrity, while protecting data-in-motion information across multiple security domains from unauthorized access and tampering by adversaries
  • Delivering rapid integration and mission-readiness, while increasing the maintainability of vehicle assets
  • Bringing a MOSA software deployment approach that accelerates system development and enables the rapid insertion of new capabilities 
  • Including a rich set of tools that accelerate module- and system-level development, debugging, testing, integration and optimization
