Model-based systems engineering (MBSE) is an approach to developing complex systems that uses software tools to create a model that describes the system. It is increasingly being used on small spacecraft, due to the advantages that it offers in terms of cost and time savings over traditional methods. This article looks at the benefits and challenges of implementing MBSE for small spacecraft.
Benefits of MBSE for Small Spacecraft
MBSE can provide significant benefits for small spacecraft projects. First, it allows the development team to quickly gain a better understanding of the system, as the model can be used to visualize and explore the design. This helps to identify potential problems and refine the design more efficiently than with traditional methods.
Second, the model can be used to automate the design process, greatly reducing the manual effort required and resulting in a faster design cycle. This contributes to cost savings and shorter development times. Finally, by creating a single source of information, MBSE helps to ensure that all stakeholders have access to the same information.
Challenges of MBSE for Small Spacecraft
While the benefits of using MBSE are clear, there are also some challenges associated with its implementation. First, MBSE requires a significant effort up-front to develop the model. This can be difficult for small teams with limited resources.
Second, the model requires regular maintenance to ensure that it accurately reflects the design. This requires dedicated effort from the development team to ensure that the model is kept up-to-date. Finally, the software tools used for MBSE can be expensive and difficult to use, making it difficult to access the benefits that MBSE offers.
Overall, MBSE can provide significant benefits for small spacecraft projects, including cost and time savings, better understanding of the system, and a single source of information for all stakeholders. However, the implementation of MBSE can also present some challenges due to the effort required to develop the model, the need for regular maintenance, and the costs of the software tools.
