In addition to Simulink, our engineers evaluated a modeling environment designed specifically for safety-critical systems. Selecting Simulink and Embedded Coder for AiRx2 development puts us on a path to closer collaboration between the research and development groups. MATLAB ® is used extensively at Septentrio, particularly by the research department.

#Localizer performance how to

DO-178C provides guidance on the use of Model-Based Design, such as how to map DO-178 objectives to model and code generation activities, through a supplemental document, DO-331: Model-Based Development and Verification Supplement to DO-178C and DO-278A.

#Localizer performance update

DO Qualification Kit supports the DO-178B certification process with resources for qualifying MathWorks software verification tools, including Simulink Verification and Validation ™ (transitioned at R2017b) and Polyspace ® code verifiers.Įditor’s Note: An update to DO-178C was recently published by RTCA, but at the time of writing, its use has not been approved by the FAA. In developing the AiRx2 software, Septentrio followed a well-defined workflow for using Simulink system models and Model-Based Design to build high-integrity systems that satisfy DO-178B.We used DO Qualification Kit to help prepare tool qualification plans for certification authorities and document tool operational requirements.

Organizations are free to map DO-178B procedures to automatic code generation using Simulink ® and Embedded Coder ®. The processes described in DO-178B cover planning, development, verification, configuration management, and quality assurance for software systems development. Published by RTCA, DO-178B outlines considerations that organizations may use to secure FAA approval of the software they develop. Because we have verified our models via simulation, the resulting generated code is virtually bug-free.ĭO-178B, Software Considerations in Airborne Systems and Equipment Certification, is the current version of the DO-178 international safety standard used to certify high-integrity commercial avionic system software, such as the software in Septentrio’s AiRx2. This approach enables us not only to find the best design but also to verify the design much earlier in development. We rapidly prototype design alternatives and evaluate them in simulation without waiting for a programmer to code them.

Model-Based Design enables us to streamline the certification process by tracking requirements, verifying the design using simulation, and maintaining the system model as the single source of truth throughout development. In addition to supporting runway approach with localizer performance with vertical guidance (LPV) and en route navigation, AiRx2 can be used for aircraft surveillance applications.Īs a high-integrity aircraft system, AiRx2 must meet the stringent development and verification requirements of the DO-178B standard. Septentrio's AiRx2 OEM is a GNSS+SBAS receiver for precision aviation applications. GNSS-based landing systems often increase runway capacity because, unlike ILS, they do not require a long, straight line of descent. Global navigation satellite system (GNSS) and satellite-based augmentation system (SBAS) technologies provide a reliable, accurate, and cost-effective alternative in places where no ILS is available. When visibility is poor, pilots often rely on ground-based instrument landing systems (ILS) to land their aircraft.
