We present a comprehensive, high-fidelity framework for long-duration thermal reliability simulations, initially developed and validated on a geostationary telecommunications satellite. Traditional methods relied on experimental formulas using minimum and maximum temperatures at specific mission phases. In contrast, our approach performs detailed thermal simulations for every single day of the...
The "Efficient Integration of Space Thermal Analysis Models" (EISTAM) R&D project investigated the feasibility of using FMI co-simulation to enhance the exchange of thermal models. Although promising results were obtained, several aspects required further refinement. The EISTAM CCN2 follow-on project successfully addressed these issues.
Firstly, EISTAM use-cases revealed that numerical...
The European Space Agency (ESA) has released an AI Harmonisation roadmap, with a focus on "Enabling Artificial Intelligence for Space System Applications." One of the key strategic objectives is to enhance space mission design with the use of AI assistants. Recently, the rapid development of generative AI, has led to significant advancements in automation in various engineering software with...
ESATAN-TMS provides an advanced thermal modelling environment for the thermal analysis of spacecraft and launch vehicles. The suite is continually being enhanced to meet current and future requirements of space projects, and to support the specific needs of thermal engineers. This presentation will focus on the latest development to be included in the coming ESATAN-TMS 2026.

Thermal modelling is a critical aspect of satellite design, ensuring subsystem performance and overall mission success under the extreme conditions experienced in space. While...
Enfys is an IR reflectance spectrometer for ESA’s Rosalind Franklin Rover (planned for launch in 2028), which has undergone rapid development since 2024 to replace the previous ISEM instrument. RAL Space is responsible for the design, analysis and test of Enfys’s electronics box. This has an unusual thermal configuration within the lander, sitting on insulating stand-offs with a dedicated...
In this presentation, We will provide an overview of the most recent developments in Systema. We will begin with a focus on the latest release, Systema 4.9.4P1, highlighting the key enhancements delivered to end users including improvements in usability, stability, and overall workflow efficiency.
We will then present a preview of the upcoming version, detailing the features currently being...
Radian is a thermal analysis software conceived to provide agility to engineers, both at modelling and computing processes. Our software is accessible through a regular web browser and counts on a scalable network of computing resources in the cloud.
Over the course of 2025, as part of the ESA BIC Madrid incubation program, our team has compared the results computed by our simulation engine...
Ansys Thermal Desktop (TD) is software for heat transfer analysis, thermal radiation, environmental heating, and fluid flow design. With a strong focus on space applications, it includes capabilities like importing and meshing CAD geometries, orbit definition for radiative analysis and 1D multi-phase flow.
The latest releases introduce several innovations like a new template launcher for...
In the space industry, thermal modelling typically relies on commercial simulation tools such as ESATAN-TMS, NX Siemens, and Systema Thermica. While powerful, these tools are often expensive and complex, particularly for systems engineers working in the early stages of mission design. To address this challenge, the Concurrent Engineering Centre at CNES has, over the past three years, developed...
With the deployment of space-based systems becoming increasingly accessible, the desire for affordable and sustainable return technologies is growing rapidly. Atmospheric re-entry from space presents extreme thermal challenges due to aerothermal heating, so the ability to predict and optimize the thermal performance of conceptual, prototype or production orbital return technologies is...
Going into cryogenic fields is always challenging for reasons such as achieving and keeping desired temperatures and stabilities for suitable time or due to temperature dependent material- and thermo-optical properties. One of the crucial goals of Thermal tests is to qualify the radiator system and with it the cold chain, and other is to correlate the Thermal Mathematical Model. Therefore, the...
Two-Phase Mechanically Pumped Fluid Loop represents an efficient technological solution to control temperature of spacecraft equipment because:
• The heat exchange in phase change is high.
• The temperature is stable during the phase change.
• The pump allows to control on the flow and so on the heat to dissipate.
The two-phase flow of fluid loop can be modeled using 3D and 1D flow...
