Training and Simulation Applications
Secure, High-Performance, Scalable Software for Distributed Simulations
Simulators and training systems are already interactive, benefitting from traditional standards such as HLA and DIS. To keep pace with the evolving battlefield, Real-Time Innovations (RTI) Connext DDS adds value to these standards by creating the security needed for evolving cross-vendor, cross-branch and cross-ally simulation requirements.
Integrators are faced with different standards for interoperability, different data and voice communications protocols and integrating legacy systems with new ones. Security requirements that did not exist when legacy simulation systems were written are now paramount.
Meeting today’s emerging threats require training environments that can be assembled and reconfigured in an agile, ad-hoc manner from ready-made components. DDS is a modern, real-time, data-sharing standard that enables open, interoperable, component-based systems.
Muscle memory, reaction time, soldier response and unit behavior are honed through consistent repetition. Effective training requires a system that provides true, high-fidelity simulation with response times closely matched to real-world scenarios. Truest fidelity is found by using the same technology that is used in systems deployed in the real world.
RTI Connext DDS is the connectivity framework that successfully meets the stringent interoperability and real-time requirements of the defense industry in hundreds of deployed systems. Connext DDS seamlessly stitches together legacy simulations while adding humans and hardware in the loop to create new live, virtual and constructive environments. Share real, augmented and virtual realities in a single lab or across multiple sites while matching physics-speed response times.
Widely Distributed, Loosely Coupled
The DDS publish-subscribe paradigm 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 the application developer from needing to know about the internals of the other subsystems required to share data, making the addition of new systems a breeze.
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 platform to address security down to the data item level while maintaining real-time response. Participants in the simulation see only the data they are authorized to see and share information only with specific team members and systems while isolating others.
Using DDS with HLA
Traditional simulation-based standards such as DIS and High-Level Architecture (HLA) are challenged by new requirements for massively distributed systems. 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.
National Advanced Driving Simulator
The US Army and University of Iowa cooperated to create several high-fidelity simulators to demonstrate how US Army vehicles and components can be tested and evaluated using virtual proving ground (VPG) technology. They needed a software solution that was truly effective at real-time, low-latency data interchange to manage the large number of simulation components working in conjunction.
FORCE Multi-Ship Simulation
Force Technology, the market leader in the design of multi-ship simulator systems, 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 tugs. They required a connectivity framework that would offer real-time data interchange between subsystems without requiring the developers to know about the internals of each subsystem added to the application.
CAE Sim XXI Full Flight Simulator
CAE’s Sim XXI full-flight simulator is regarded by pilots around the world 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. Achieving this level of full-flight simulation 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. They tasked the US Navy High Performance Distributed Computing Project (HiPer-D) with creating test bed demonstrations, based fully on COTS technology, that would allow NAVSEA to investigate technologies supporting real-time, distributed, scalable, fault-tolerant, heterogeneous computing systems to be used in combat systems.
