Thermal analyses are performed throughout the entire life cycle of a space project, from the first rough architecture trade-offs to the last in-orbit simulations.
In general, they consist in building a more or less complex thermal model, running different sizing cases and post-treating them. These activities are conducted by “thermal analysts” who are specialized in the different pre-post and...
“Development of a new software tool for thermal analysis of satellite harnesses”
• Ewin Bloem (Royal Netherland Aerospace Centre), edwin.bloem@nlr.nl
• Roel van Benthem (Royal Netherland Aerospace Centre), roel.van.benthem@nlr.nl
The harness sizing for space applications is defined by derating rules that are specified in international standards such as the ECSS-Q-ST-30-11C Rev 1 (ESA,...
ESATAN-TMS provides an advanced thermal modelling environment for the thermal analysis of spacecrafts 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.
A major focus of ESATAN-TMS development this year has been on providing facilities within Workbench to further...
During this presentation, we will compare and evaluate the different workflows available in Simcenter 3D PCB Exchange and Simcenter 3D Space System Thermal for printed circuit board assembly analysis in the context of spacecraft thermal design. Component reliability is heavily dependent on temperature and so PCA thermal design and simulation is an important aspect of spacecraft development....
There are current necessities of real-time simulation and satellites model exchanges with launchers. We are developping a geometrical model reduction (currently manualy done in the industry) complementary with a TMM reduction module (done by tools such as TMRT). A budget of faces for GMM is almost always imposed (Launcher or DSS constraints). The presented model reduction tool is physics...
The thermal-hydraulic design and analysis of the PLATO focal plane assembly (FPA) and normal-front end electronics (N-FEE) thermal-vacuum calibration experiment is presented. Optical calibration of the instrument, which consists of a 300mm diameter Ti-6Al-4V FPA with 4xCCDs, connecting via flex-cables to the 15W N-FEE, requires two separate thermal control loops with temperature ranges of 150K...
The Lunar Orbital Platform-Gateway (LOP-G) space station is one key element of the NASA Artemis Program, which has the goal to bring humans back to the moon by 2024 and to provide a sustainable infrastructure for future missions. One of the LOP-G modules is the European System Providing Refuelling, Infrastructure and Telecommunications (ESPRIT) module, which contains, among others, the xenon...
In the past year, two Systema versions have been issued. First Systema 483P2 has been released last May 2020 to address some issues signalled by users.
Then the version of Systema-Thermica V4.9.0 was released and available to users in fall 2020. This new version embeds features presented during the last edition of ESTEW, such as the Orekit library for enhanced accuracy of in-orbit...
The Long-Term Support version of Systema-Thermica V4.8.3 was released last year. As day-to-day users, we conducted an extensive validation campaign based on various realistic use cases including both Telecom and Observation satellites/instruments.
First, the presentation will focus on this validation campaign implementation including the definition of the use cases, the validation criterion...
To prevent thermal induced breakdown, thermal modelling is a crucial task during each design phase of a new space mission. Monte Carlo ray tracing, while computationally demanding, is usually the go-to method to simulate thermal energy transfer. State of the art thermal modelling suites, such as ESATAN-TMS, usually rely on a CPU-based implementation of Monte Carlo ray tracing.
Due to the...

EnVision is one of the three candidates for ESA's next medium class mission with the aim to explore the link between geological activity and the Venusian atmosphere. The mission consists of a suite of instruments to probe various layers of the Venus atmosphere, surface and sub-surface.
The topic of this presentation is a preliminary thermal study for the VenSpec-H instrument developed by...
The presentation will give a short overview of the ongoing work on in the area of thermal analysis data exchange and specifically STEP-TAS.
The ongoing work with tool vendors to provide more robust and feature complete STEP-TAS interfaces will be presented, as well as some perspectives for the verification of STEP-TAS models. The latest converters for Thermal Desktop models will also be...
