Simulation

Simulation environments are often complex systems made up of diverse, heterogeneous components. These environments require communication infrastructure for sharing data between subsystems, and typically there is a high demand for real-time data exchange, with low latency and high reliability.

RTI Data Distribution Service middleware solves the requirement for high-performance, low-latency data communications infrastructure even in the most complex, diverse simulation environments. RTI's proven commercial off-the-shelf (COTS) middleware solution is in use in a number of large-scale commercial simulators today, primarily because it is based on the only middleware technology – OMG Data Distribution Service (DDS) - that can keep up with the real-time performance demands of many of these applications. Unlike other commercial networking middleware technologies, DDS was designed specifically to ease the development of heterogeneous distributed systems with real-time data distribution requirements.

Additionally, 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.

Customer Profiles

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 middleware 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, 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 middleware 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.
