Astos Solutions GmbH is a trusted partner for advanced engineering software and services in the aerospace industry. Headquartered in Germany, the company has over two decades of experience supporting leading space agencies, launch service providers, satellite operators, and research institutions worldwide. Our core mission is to empower innovation through cutting-edge tools for mission analysis, optimization, and verification — from concept to deorbit.
Our Flagship Product: ASTOS – The All-in-One Software Suite for Space Applications
At the heart of our portfolio lies ASTOS – the Analysis, Simulation and Trajectory Optimization Software. ASTOS is a modular, highly customizable, and fully integrated software solution that covers the entire lifecycle of a space mission:
- from early-phase system concept design,
- through mission performance analysis,
- to detailed trajectory simulation,
- and even end-of-life disposal such as deorbitation or controlled re-entry.
ASTOS combines multi-domain modelling, realistic 6DOF simulation, and multi-objective optimization with a user-friendly interface and automated reporting. Engineers can simulate complex systems involving launchers, satellites, rovers, re-entry vehicles, or even interplanetary spacecraft, with full control over GNC logic, propulsion, power, thermal, and environmental constraints.
Whether your project involves CIS-lunar transfers, HALO orbits, Lagrange point missions, or small satellite constellations, ASTOS offers you a reliable and high-performance framework to design, optimize, and validate your mission.
What Makes ASTOS Unique
End-to-End Functionality: From system-level modeling to Monte Carlo simulations and launch window optimization – all in one integrated environment.
Advanced Guidance, Navigation & Control (GNC): Design and verify control logic using MIL, PIL, or HIL configurations.
Flexible Architecture: Use ASTOS as a standalone application or connect it to your existing MBSE toolchain or test benches.
Hardware-in-the-Loop Ready: Real-time simulation interface for system-level testing and verification.
3D Visualization and Virtual Reality: Embedded AstroView module enables immersive simulation review with terrain overlays, sensor FOVs, or orbital elements.
Robust Optimization Engines: Solve challenging multi-disciplinary trade-offs using global optimization strategies.
Export-Compliant Licensing: ASTOS is classified as dual-use software and delivered under strict EU export compliance, with flexible licensing models (annual, floating, etc.).
Why Astos Solutions?
Specialized Know-how:
Unlike general-purpose software vendors, we focus exclusively on space mission analysis and simulation. This singular focus allows us to offer a level of depth and precision that meets the stringent demands of space programs.
Proven Heritage:
ASTOS has been trusted in hundreds of missions, studies, and space qualification projects. From LEO satellite deployment to Mars mission feasibility studies, our tools are used by ESA, DLR, national agencies, universities, and private NewSpace companies alike.
Tailored Support & Services:
We go beyond software. Our customers benefit from customized trainings, technical consulting, feasibility studies, and mission support services provided by a seasoned team of aerospace engineers.
Innovation-Driven Development:
With each major release — including the recent launch of ASTOS 10 — we introduce industry-first capabilities such as:
- real-time plotting of simulation metrics
- co-simulation with MBSE environments
- integration of terrain models and satellite imagery
- advanced finite-element modeling
- and extended support for AI/ML-based optimization.
Adaptability to the NewSpace Market:
ASTOS supports rapid design loops and constellation scenarios, which are essential for start-ups and NewSpace innovators. Our Camera Simulator, AOCS SCOE, and Cloud Licensing System (CLS) further support agile development and remote collaboration.
