RTI Real-Time Middleware Provides Greater Reliability, Flexibility for Distributed UAV Designs

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) May 25, 2008 -- Technology Currently Adopted by Insitu and General Atomics

SAN JOSE, CA–May 27, 2008–Real-Time Innovations (RTI), The Real-Time Middleware Experts, today summarized its success in providing real-time messaging and data distribution technology to unmanned autonomous vehicles (UAVs). RTI also emphasized its commitment to future UAV design and development advancements. The use of RTI middleware can make UAVs more reliable and increase flexibility as mission parameters change and evolve.

RTI middleware, which complies with the Object Management Group (OMG) Data Distribution Service for Real-Time Systems (DDS) standard, has been adopted by several leading developers of UAV systems. Insitu Inc. is using RTI software in multiple portions of platforms, such as on UAV airframes, in ground control stations (GCSs) and in future air-to-ground communications. On the airframes, RTI connects flight control computers, sensors and on-board application computers. Within GCSs, RTI connects the systems that decode data feeds, analyze a UAV’s situation and interface to the operator control. RTI middleware is also being used in the General Atomics Aeronautical Systems, Inc. (GA-ASI), Advanced Cockpit GCS.

“UAV systems are a great application for RTI’s real-time middleware technology,” explained David Barnett, vice-president of Marketing at RTI. “RTI provides features such as highly tunable real-time Quality of Service and support for multiple transmission protocols, including unreliable network connections. These characteristics enable UAV systems to operate more reliably and ensure high performance in a wide variety of missions.”

The DDS standard provides a highly scalable infrastructure for evolving UAV systems. Instead of relying on hard-coded or pre-configured connections, it allows applications to communicate in a loosely coupled fashion via anonymous publish-subscribe messaging. Applications communicate by indicating the types of data that they publish and subscribe. Messages are automatically routed between publishing and subscribing applications based on their content. DDS addresses both cross-vendor source-code portability through a standard Application Programming Interface (API) and multi-vendor run-time interoperability through a standard wire protocol.

RTI at AUVSI
RTI’s real-time messaging and data distribution technology for UAV applications will be demonstrated at the AUVSI’s Unmanned Systems conference on June 9-11at the San Diego Convention Center, booth 2313. For an appointment, please contact the RTI Sales department at 408-990-7400.
