gncde

  • A Template is the central resource in gncde common to all processes 
  • The Template contains the organization and structure of all available resources (existing models, data structures...) applicable to the development of a new GNC design 
  • Once a project is started, gncde allows the re-use and customization of a Template in order to integrate new requirements and characteristics of the specific mission scenario 
  • gncde Templates are of two types: Analysis and Design Templates or Mission Templates. Both are scenario representations (including the spacecraft, real world, onboard processor models…) conceived to support the GNC design process at these separate design phases:

    • Analysis and Design Template: Supports the first tasks involved in the GNC design process in a simplified “Real World” model. It provides the linear state-space representation of the “plant” models and “sensor” models and is prepared to perform simplified simulations (specific for each GNC mode) that allow the basic performance assessment of of the controllers and estimators being designed
    • Mission Template:Supports the full performance assessment of a high-fidelity simulation model. It also includes the verification of high-level requirements, evaluating not only the GNC functions but also other on-board functions (MVM) against complete and, in general, non-linear models of the “Real World”. It includes a spacecraft model, sensors, actuators, dynamics, kinematics and environment as well as all necessary perturbations.

gncde also includes a wizard to walk the user through the development of a completely new Template from scratch, with the proper infrastructure components. Several Templates developed by GMV are available in gncde for default classic mission scenarios.
