Sperry Marine uses RTI to enable seamless integration of shipboard navigation systems with other real-time clients
SANTA CLARA, CA-October 9, 2006-Real-Time Innovations (RTI), The Real¬ Time Middleware Company, announced that Sperry Marine, a Northrop Grumman Company, has incorporated RTI Data Distribution Service into the development of a versatile and scalable Navigation Data Distribution System (NavDDS) that seamlessly interfaces a wide variety of electronic navigation sensors with shipboard systems and equipment requiring navigation information. The product was released and shipped to Sperry Marine's first customer in August 2006.
The NavDDS solution can be configured to support anything from a simple half-duplex interface with a single sensor up to a large-scale system with dual- redundant servers running complex software that distributes time-critical data from multiple sensors. NavDDS can also disseminate navigation information via traditional transport mechanisms such as RS-422 and synchro and via Ethernet by leveraging RTI's real-time publish-subscribe messaging capabilities.
"NavDDS is an excellent example of the powerful integration capabilities provided by RTI Data Distribution Service," said David Barnett, vice president of Product Management for RTI. "NavDDS demonstrates the flexibility of RTI's publish-subscribe messaging model for applications that share real-time data between multiple producers and consumers."
A significant advantage of employing RTI Data Distribution Service within the NavDDS system is because the publish-subscribe architecture does not require specific design knowledge of remote devices leveraging the middleware system (such as weapon-and-command or control systems). Furthermore, the
RTI auto-discovery capability gives system designers the flexibility to seamlessly add entirely new systems to the architecture without having to reconfigure existing subsystems.
"From a technical standpoint, RTI Data Distribution Service is a key technology in that it enables data from any navigation system to be accessible to any other shipboard system," explained Guy Babineau, director of Engineering for Sperry Marine. "RTI's Professional Services Department helped us get started quickly and was very effective in working with us to address issues encountered during the project."
Of importance to Sperry Marine was the ability to work within the context of an open architecture so devices with different data formats and interfaces could be easily integrated into the network. An additional NavDDS requirement was to distribute real-time data over the primary Ethernet transport, which is inherently non-deterministic. RTI Data Distribution Service is based on the Object Management Group Data Distribution Service (DDS) and provides the technical functionality that helped to meet these design challenges.
An important ingredient to success for any project team is the ability to quickly become proficient and productive in the use of adopted technology. RTI delivered effective training that was essential in providing the Sperry Marine engineering team with knowledge of the fundamentals of RTI Data Distribution Service. RTI also worked closely with the team to accelerate development and resolve issues encountered during the course of the project.
"Responses to our issues were extremely fast," commented John Mouring, Sperry Marine Engineering department head for Software Systems. "RTI had people in our region that responded immediately and were advocates for our requirements and communicated them to RTI management. We received near- instant feedback and resolution."
About RTI Data Distribution Service
RTI Data Distribution Service (formerly NDDS) is networking middleware that implements a real-time publish-subscribe communications model and allows distributed processes to share data without concern for physical location or network architecture. RTI Data Distribution Service is an open-architecture platform based on the DDS. RTI Data Distribution Service is field-proven in a wide variety of time-critical applications. It is available with C, C++ and Java programming interfaces.
