NASA - Orion GN&C: MATLAB and Simulink Standards

The Orion Guidance, Navigation, and Control MATLAB and Simulink Standards document describes the modeling standards and guidelines that the Orion Crew Exploration Vehicle (CEV) Flight Dynamics Team (FDT) are using while developing and coding the GN&C algorithms using Simulink, Stateflow, the Embedded MATLAB subset of the MATLAB language, and Embedded Coder.

The Orion NASA/Contractor team used the MathWorks Automotive Advisory Board (MAAB) guidelines as a starting point, and updated and expanded it as required for the Orion program. The standards provide guidelines for several aspects of the GN&C models, including stylistic rules, modeling tool selection, and configuration setting, which affect model readability as well as the generated code.
