ASTOS 10 – Major Release
[2026-02-27]
Astos Solutions proudly announces the release of ASTOS 10, representing the most significant evolution of the ASTOS platform in recent years. ASTOS 10 introduces major advancements in launcher safety analysis, multi-body dynamics, structural modeling, mission analysis, visualization, hardware-in-the-loop integration, and computational performance—while establishing a modern backend architecture designed for long-term scalability and regulatory compliance.
Launcher & Safety – A New Standard
- Major expansion of Risk & Safety Analysis, including additional explosion and debris models and full support of the MPL methodology.
- Unified Safety Analysis module combining launch and re-entry safety into one consistent workflow (aligned with the latest risk assessment procedures).
- FAA-compliant risk assessment workflow: ASTOS 10 is currently in FAA qualification; full FAA acceptance is expected in 2026.
Multi-Body Dynamics & Structural Modeling
- Integrated Multi-Body & Flexible-Body Dynamics (MBS) for stage separation, sloshing effects, and payload release simulations.
- New and enhanced FEM module to compute mode shapes and natural frequencies via FEM, with direct coupling to multi-body simulations for increased structural fidelity.
Mission & Scenario Modeling
- Branching is back: concurrent simulation of main stage and return stages within a single scenario.
- Extended multi-vehicle and satellite mission modeling; Mission Analysis and Branching are available already in ASTOS Basic.
- Near-instantaneous Coverage Analysis enabling rapid trade studies and faster design iterations.
Visualization & AstroView Enhancements
- Real-time plotting and animation during simulation execution for live monitoring and improved debugging (supports very large simulation files).
- Advanced 3D visualization with VR headset support, terrain models, and textured globes.
- High-resolution Earth/Moon/Mars textures and DEM data streamed on demand from ASTOS servers.
- Enhanced analysis tools including elevation profiles, plot overlays in 3D environments, and visualization of aerodynamic vector fields.
Integrated Aerodynamics
- Embedded DrNUM CFD solver for generation of aerodynamic force and moment coefficients, fully integrated into the ASTOS workflow—reducing external CFD preprocessing for early design phases.
Performance & Automation
- Significant performance improvements: faster solver execution, optimized memory usage, and enhanced parallelization for batch simulations.
- Batch Mode Inspector with manual stop functionality.
- GPU acceleration roadmap for Monte Carlo simulations; first customer benefits expected within 2026.
EGSE, MIL, PIL & HIL Integration
- Full integration into modern EGSE environments.
- Seamless transition from MIL → PIL → HIL with an operator GUI for PIL/HIL execution.
- Hardware-in-the-loop ready using dSPACE SCALEXIO with ASTOS as simulator, enabling consistent workflows from concept design to hardware validation.
Platform & Licensing Evolution
- New licensing backend designed for flexible multi-user and multi-project environments, supporting modern workflows including HIL, cloud-based usage, and continuous integration.
- Backward compatibility: ASTOS 9 scenarios can be opened using a migration assistant.
- The annual licensing model ensures continuous delivery of safety/compliance updates, performance upgrades, and new capabilities such as advanced visualization streaming and GPU acceleration.

The "HyGo - Hybrid, Green Upper Stage" project has been kicked off!

The "HyGo - Hybrid, Green Upper Stage" project has been kicked off!
The aim of the project is to develop an upper stage for an orbital rocket using innovative and cost-saving technologies. The project is funded by the state of Baden-Württemberg as part of the invest-BW grant. The development of the central part of a rocket requires good coordination of the work areas such as structural development, fluid system, aerodynamics, electronics as well as software development. The foundation for this was laid at the first project meeting.
The participants Astos Solutions GmbH, enGits GmbH, the Institute of Aircraft Systems at the University of Stuttgart and HyImpulse Technologies GmbH stand for "Rocket Technology, Made in Baden-Württemberg". Competence in the "New Space" sector is being built up and jobs created in the region. In addition to overcoming major technical hurdles, this project contributes to the sovereignty of Germany and Europe and secures access to space.
PEET 1.1.0 Released
[2022-04-25] An extensively revised and extended version 1.1 of PEET is now available.
The main updates of the tool cover:
- Specific support for telecommunication missions (analysis features)
- Implementation of a user-defined post-processing feature that allows integrating own algorithms
- Improved user-friendliness based on received feedback (editing, reporting, plotting)
- Faster evaluation for quick-assessments (skipping auxiliary results and/or using lower resolution) and batch-mode operation
- Extended metrics for time-windowed relative errors
- Specific support for selected transient error types
- Contribution analysis for each error source and contributor blocks (percentage of contribution to total error)
ASTOS 9.22 Released
[2022-03-28] The release of ASTOS 10 is getting closer. Meanwhile ASTOS 9 has been improved through multiple updates in the last few months from version 9.19 to our newest release 9.22. These releases fixed bugs, added new features and improved existing ones:
- The Bending Moment output function has been added.
- The external dependencies of the MBS functionality have been updated. Now MSYS2 is required and available by download from Your Astos
- An experimental explosion model has been added to the launch safety analysis that better fits to the launch scenario than the former EVOLVE model.
- The multi-body dynamics simulation allows now predefined movements between vehicle units (translation and rotation). The movement is defined as a profile.
- The magnetorquer inductance is now an optimizable parameter. Furthermore, Magnetorquers can now be controlled via the electrical current alternatively to the supply voltage.
- The Link and Relay definitions in the coverage analysis received the parameter Link setup time to improve the realism of the coverage results.
- The Multi-Membrane-Tank component has been introduced. It allows for modelling a set of membrane tanks that are interconnected.
ASTOS 9.19 Released
[2021-07-27] As the release of ASTOS 10 is getting closer, the current version 9 of ASTOS is receiving its nineteenth update.
In the last releases, new functionalities were added for the application areas Launch Safety Analysis and Closed-Loop Simulation.
Since version 9.15 ASTOS offers the possibility of analyzing the so-called distant focusing overpressure when modeling explosions. You can also analyze the spread of the chemical plume during launch. For a more precise evaluation of the launch risk, the population models can now also be replaced or augmented locally with user-provided data.
Existing models have been expanded for closed-loop applications in which ASTOS is used as a dynamics, kinematics and environment simulator and for modeling actuators and sensors. It is now possible to use the GNSS navigation model, which was originally only developed for the mission analysis, for the detailed modeling of a GNSS receiver taking into account the antenna geometry, visibility of GNSS satellites and the available functionality of the receiver (e.g. number and type of channels).
The integration of ASTOS in automated tool chains is an important topic, especially when it comes to operational applications. It is now possible to start complete batch processes via the command line and reports can now be generated in a text-only format. Latter allows the generation of very customizable data files suitable for import into other tools.
The possibility of coupling ASTOS with other expert tools is an important selling point. Since version 9.17 the properties of flexible bodies can be imported from a NASTRAN file and since version 9.19 ASTOS can be used as a server for an FMI cosimulation, which enables completely new application scenarios.
To name the many other new features here would go beyond the scope. We therefore recommend downloading the latest version of ASTOS and testing its features. The release notes contain a complete list of all new functionalities.
