The use of simulation technology is essential in modern manufacturing. Its importance is particularly acute in the development of mission-critical spacecraft, where once launched, there is no redoing the process. In Japan, the adoption of digital engineering is accelerating across industry and academia, with initiatives such as JAXA’s “Small Technology Innovation Satellite Research and Development Program,” “CHAIN-X” in the aircraft development field, and the establishment of “JAMBE (Model-Based Engineering Promotion Center)” with the participation of domestic automobile manufacturers. Meanwhile, Western manufacturers and emerging space companies are already leading the way in utilizing this technology. To ensure future international competitiveness, process innovation from the design stage onward is an urgent necessity. This seminar will explore the role of digital engineering in space development, where failure is not an option, from multiple perspectives, including examples from Western manufacturers. This seminar will provide insights for companies both currently engaged in space development and those embarking on development, on how to enhance their competitiveness. We look forward to your participation.

High reliability and safety are essential for space development, and to date, engineering has relied on extensive document-based engineering, including specifications, design documents, and test records. However, this approach has been criticized for leading to inconsistent information and inefficient communication between organizations, resulting in longer development times and increased costs. This presentation will discuss the Multi-Disciplinary Analysis and Optimization (MDAO) methodology, which addresses these issues, and the introduction of Digital Engineering (DE), which is essential for its implementation. DE integrates analytical models from multiple disciplines, explores optimal solutions in the early design stages under unified data management, and aims to maximize the target system performance. Ansys is developing a DE platform that integrates system models and physical simulations. This presentation will outline the role and collaboration of Ansys simulation in DE promotion. Furthermore, we will use a specific application example, “environmental monitoring mission using a satellite constellation,” to explain the DE workflow, from requirements definition to detailed design, step-by-step.

In a startup environment where rapid development and visible results are required with limited funding, establishing a “design process driven by mission requirements” is beneficial for advancing spacecraft development quickly and reliably with limited resources. This session will introduce an approach that starts with mission (ConOps) and SysML models and uses Ansys ModelCenter to achieve mission-level design optimization and strengthen cross-departmental collaboration by linking various tools. In fact, global aerospace companies such as Northrop Grumman, Airbus, and Boeing are using this system to streamline the design and verification of complex spacecraft in a simulation-driven, traceable manner. Expanding this digital engineering platform offers many benefits, including replacing physical testing with computer testing, reducing redesign costs, improving verification speed, accelerating inter-organizational collaboration, and ensuring traceability of various design proposals and data.

Today’s advances in digital technology have brought a new form of digital engineering (DE) to the engineering world, using a “Model-Analyze-Build” methodology to replace the traditional “Design-Build-Test” methodology. On the other hand, in order to respond to the current severe security environment, it is becoming increasingly important to promote defense innovation that incorporates cutting-edge technologies and rapidly creates superior equipment. In this article, we will discuss the usefulness and challenges of applying DE to promote defense innovation in the present day, when various things and events in physical and virtual spaces are connected by IoT technology.

Maintaining the performance of telescopes and observation instruments operated in space is an extremely important issue. The harsh space environment, particularly the intense vibrations during rocket launch and the rapid temperature changes caused by sunlight and shade in orbit, can cause minute deformations in the structure of equipment, significantly degrading optical performance. To improve the performance and ensure stable operation of satellite systems, where failure is unacceptable, it is essential to accurately simulate these effects in advance and take countermeasures at the design stage. In this presentation, we will introduce an overview of STOP analysis, which integrates thermal, structural, and optical analyses, and introduce the analysis method through an application example using the James-Webb Space Telescope (JWST) , a space telescope model . This will demonstrate an approach to improving the reliability of optical system designs that take the space environment into account.

With the development of next-generation Earth Observation and space communications systems, the demand for accuracy in RF design and channel modeling is growing more than ever. This session will demonstrate how Ansys’ cutting-edge simulation technology is supporting innovation in the fields of space communications and radar systems. Ansys HFSS achieves the “gold standard” of accuracy based on the finite element method (FEM). By combining fast solvers such as the Shooting and Bouncing Ray (SBR) method and the Integral Equation (IE) method, it is possible to accurately and efficiently analyze complex propagation environments. Furthermore, the GPU-accelerated SBR solver enables near-real-time propagation analysis even in extremely complex scenarios, from densely populated urban areas to lunar environments. Ansys tools also enable SAR image simulation incorporating terrain data and CAD models, helping to generate high-quality synthetic datasets for AI and machine learning. Finally, we will introduce future directions for integrating Ansys STK and NVIDIA Omniverse system-level platforms to combine high-fidelity physical simulation with real-world mission design.

This session will introduce examples of design and verification using multiphysics analysis to address the radiation and thermal countermeasures required for satellites and spacecraft. Radiation analysis supports reliability assessment in the space environment by performing transient analysis based on the Total Ionizing Dose Effect. Thermal design support from the early stages also enables rapid launch of thermal control design for launch vehicles and satellites. Furthermore, we will introduce a simple GUI-based workflow for creating solar panel models that can be linked to STK.

In rocket development, there’s only one way to succeed—and countless ways to fail. From the first sketch to first flight and beyond, simulation and analysis tools are essential for turning complex ideas into reliable launch systems. These tools allow teams to explore performance, uncover failure modes, and validate designs—long before hardware is built. As launch programs become more visible and competitive, reducing technical risk also helps buy down programmatic risk—protecting funding, schedules, and reputation. Simulation enables engineers and leaders alike to make confident, data-driven decisions that improve performance and reliability across the entire lifecycle. This session will show how modern simulation and analysis support everything from materials and propulsion to mission operations, and how these capabilities naturally evolve toward digital engineering practices that enhance collaboration and insight. The result: faster innovation, greater confidence, and a stronger foundation for mission success.
