Training for today’s military threats requires simulated environments that can be assembled and reconfigured in an agile, ad-hoc manner from ready-made components. RTI Connext DDS is the platform that brings distributed simulations together in a secure, high performance, scalable environment. Based on the DDS standard, it has the necessary security and interoperability requirements for cross-vendor, cross-branch and cross-ally simulation of the evolving battlefield.
Connext DDS seamlessly stitches together legacy simulations while adding humans and hardware in the loop to create new live, virtual and constructive environments. It provides rapid response times for real, augmented and virtual realities in a single lab or across multiple sites.
Connext DDS is based on a publish-subscribe model that allows simulation subsystems to share data without requiring unique interfaces for each new system. The new system merely needs to subscribe to the desired dataset. This frees application developers from having to create custom data-sharing code within subsystems, enabling rapid integration and expansion of new variables per training exercise.
Securing Complex Simulation Environments
Modern simulators and training systems must share data with operational systems, presenting new security and performance challenges. Connext DDS Secure is the world’s first data-centric framework to address security down to the individual data object level while maintaining real-time response. It shares information only with authorized systems and participants, preventing blanket access for all users.
Using Connext DDS with HLA
Traditional simulation-based standards, such as Distributed Interactive Simulation (DIS) and High-Level Architecture (HLA) are challenged by new requirements for massively distributed systems. Connext DDS provides the plug-and-play interoperability, real-time performance and fine-grained security lacking in HLA so the two can work together. Existing HLA applications can be bridged to a Connext Databus, or DDS can be used as a transport for HLA data objects.
Customer Use Cases
National Advanced Driving Simulator
The U.S. Army and the University of Iowa jointly developed several high-fidelity simulators to demonstrate how military vehicles and components can be tested and evaluated using virtual proving ground (VPG) technology. Connext DDS provided the software for real-time, low-latency data interchange to manage the many simulation components working concurrently.
FORCE Multi-Ship Simulation
Force Technology created the world's first system to provide a complete environment for training tugboat captains in maneuvering large vessels, such as oil and gas tankers into restricted spaces using multiple boats. Connext DDS delivered the connectivity framework that offered real-time data interchange between subsystems without requiring the developers to know specific code for each subsystem added to the application.
CAE Sim XXI Full Flight Simulator
Pilots around the world consider CAE’s Sim XXI full-flight simulator as the closest simulation of the true experience of flight. It delivers breakthrough visual realism, precise cockpit replication, high-fidelity avionics simulation, and flight and ground-handling characteristics indistinguishable from the aircraft. Connext DDS helps to achieve this level of full-flight simulation that involves a variety of complex subsystems sharing and processing data in real-time.
US Navy HiPer-D
The Naval Sea Systems Command (NAVSEA) Dahlgren Division needed to investigate how to apply advanced technologies and concepts to the Naval Surface Ship Anti-Air Warfare (AAW) problem domain. Connext DDS was used by the US Navy High Performance Distributed Computing Project (HiPer-D) to create test bed demonstrations, based fully on COTS technology, that enabled NAVSEA to investigate technologies supporting real-time, distributed, scalable, fault-tolerant, heterogeneous computing systems to be used in combat systems.
