The objective is to develop and test a VHTS system emulator based on the functional modelling/programming of the system elements. This approach will enable payload-constrained system analysis and optimization not possible with current tools relying on procedural programming. At least two VHTS systems will be implemented to test the emulator.Targeted Improvements:Enabling generic payload constrained system analysis and system optimisation not possible today.Description:Current analysis and optimisation tools require setting up and implementing very complex simulation scenarios before the performance of a VHTS system can be assessed. Moreover, those scenarios are specifically tailored to the coverage and payload configuration requiring already a detailed knowledge of the system design. This approach provides a high level of precision, but limits the optimisation capabilities and the flexibility to explore other design options. This results in specialised SW tools that are specific to a payload architecture and thus difficult to reuse and/or expand for different scenarios.To achieve simulation tools that are generic, reusable, maintainable, reliable and easily expandable, this activity will follow a functional modelling approach. By combining the principles of model-based system engineering with those of functional programming the activity will develop a system emulator that allows satcom engineers to explore the design space of satcom systems within given payload constraints. This new approach has the potential to enable payload-constrained system analysis and optimisation not possible with current tools. The emulator will be capable of estimating the system capacity for different payload components, configurations/architectures and constraints. All types of antennas will be available as options and their pattern will be synthetically generated. The payload configuration options will include OBP or bent-pipe architectures as well as different feeder link technologies. Two VHTS systems will be implemented in the emulator and its system optimisation capability will be tested.
