Modelling and Simulation

About this theme
Simulation is a key activity in support of the specification, design, verification and operations of space systems. System modelling and simulation can support a number of use cases across the spacecraft development life-cycle, including activities such as system design validation, software verification & validation, spacecraft unit and sub-system test activities, operations, etc.

With steadily increasing adoption of modelling and simulation, significant benefits of a more consistent approach to simulation across project phases have been achieved. Effective use of modelling and simulation within the system engineering process is clearly desirable, to minimise the overall space programme schedule, risk and cost. In industrial facilities, simulation and test systems are more commonly used, and are capable of bridging multiple projects and phases. Furthermore, significant commonality exists between the infrastructure and models developed for each of these facilities. The following objectives have been identified:

  • Maximise the benefits of using modelling and simulation in support of Systems Engineering
  • Reduce effort in developing and maintaining simulators over the system life-cycle.
  • Preserve investment in modelling a system, independently of the tools.
  • Improve collaboration between involved teams and communities by addressing distribution and interoperability aspects.
  • Facilitate and encourage reuse from phase to phase, project to project.

The contribution of Modelling and Simulation is particularly important for the focus in 2023, where we encourage presentations of developments and technologies to establish a “Digital Twin”, as well as their use in an industrial context.
