The RTI Connext TSS Advantage

RTI Connext TSS is certified conformant to the FACE TSS software standard. Connext TSS is a member of the RTI Connext product suite, making it easy for component developers and systems integrators to take advantage of both the FACE technical standard and the DDS standard. Connext TSS offers decentralized architecture with peer-to-peer communication for low latency and no single point of failure, meaning no brokers or servers are required.

To accelerate the integration with FACE conformant software components with legacy systems, systems without data models and non-FACE conformant systems, RTI offers commercial tools enabling the rapid translation of data from different systems into a FACE solution stack.

RTCA DO-178C DAL A Certification Evidence

RTI Connext TSS offers commercial RTCA DO-178C and EUROCAE ED-12C DAL A certification evidence audited by a third party for rapid and reliable airworthiness review. This evidence contains design documents, high- and low-level requirements, project documents, SOA audit memos, test results and more. This drives down the airworthiness cost and risk in programs requiring safety certification.

RTI FACE Partner Ecosystem

RTI has the most comprehensive FACE Partner Ecosystem in the industry. RTI has proven integrations with over twenty hardware and software providers that accelerate the development and deployment of FACE platforms. Most of these partners have commercial RTCA DO-178C and/or DO-254 certification evidence, and many have RTCA DO-330 qualified tools that simplify DO-178C objectives, reducing program costs and risks while accelerating airworthiness.

RTI's Success-Plan Services connect customers with our experts who can increase efficiency with Connext TSS and accelerate integration efforts into new or existing infrastructure. The building blocks of our Success-Plan Services are our time-tested services, called Xcelerators, which can be arranged as customized training or part of an overall Success-Plan. We offer a variety of options for training, architectural analysis and design support, whether your target is the FACE General Purpose or Safety profiles.
