NAV CANADA is set to improve its NAVCANtrac air traffic management (ATM) system with Real-Time Innovations (RTI) Connext Data Distribution Service (DDS) middleware.
NAV Canada said that it selected the RTI middleware platform after a successful implementation of the evaluation stage in order to replace the first-generation distribution architecture of its NAVCANtrac ATM system.
The latest platform will enhance ATM, automating and integrating flight information from multiple sources.
NAV CANADA chief technology officer Sid Koslow said that RTI Connext DDS was selected for its extensive compliance with the Object Management Group (OMG) DDS standard, as well as its high security rating, wide support of tools and programming languages, and reputation for performance, scalability and 24/7 reliability.
"It is a good fit to support current and future software development for the NAVCANtrac distributed architecture," Koslow added.
RTI product management VP David Barnett said that Connext DDS will ease the transition of the currently operational and proven NAVCANtrac system to a more flexible, scalable and interoperable ‘open architecture’.
"This will accelerate the release of enhancements while reducing software development and integration costs," Barnett added.
RTI Connext DDS’s ATM and support system processing capabilities will improve the existing level of automation and integration of flight data between the company’s air traffic control sites, multiple surveillance sources and external systems.
The platform will also be used for internal system communications, as well as perform as the interface to external system communications.
With NAVCANtrac, traffic from a wide national airspace can be viewed and managed using an advanced graphic display.
It allows safer and more efficient management with flight plan generation, data communication and sector coordination, in addition to modern ATM decision support functionality.
Using 4-D flight trajectories, NAVCANtrac offers accurate information on the current and future position of every aircraft through space and time, enhancing safety and flight predictability.
It uses the latest surveillance fusion technology to display a seamless presentation of targets generated from several surveillance sources.
The deployment of RTI Connext DDS will complete the replacement of the middleware software for NAVCANtrac and reduce the volume of application code while providing a base for further technology enhancements.
