SSOS v0.8.2 Released - Now with Configurable CMG Control Dynamics
We’re pleased to announce the release of SSOS v0.8.2, now including configurable CMG (Control Moment Gyroscope) control - a key component in attitude control systems for large spacecraft like space stations.
This update finalizes a series of improvements around dynamic modeling, modular control, and simulation-driven development. It brings us closer to our goal of building a complete, ROS2-native platform for space station system development.
A quick overview of what’s included and what’s coming next is shown below.
What’s included in v0.8.2
This release focuses on building blocks that are familiar to robotics developers, but applied to the space domain:
-
Modular modeling of a space station
Define sensor and actuator configurations using structured descriptions -
Physics simulation
- Attitude control logic based on torque models
- Gravity-gradient disturbance modeling
- Parameterized dynamics for CMGs, enabling system tuning and integration
- Thruster support for backup and hybrid control
-
Ground station interface
- Database logging and retrieval
- Integration with visualization tools (e.g., yamcs)
-
Simulation support
- Basic physics simulator
- Software-in-the-loop (SILS) structure to enable integration with external software
-
ECLSS (Environmental Control and Life Support System)
- Initial integration under way

What’s next in v0.8.3
- CMG unloading strategies
- Thruster reboost modeling
- Additional external torques (e.g., air drag, magnetic effects)
- Runtime updates of mass properties
- Full-loop ECLSS simulation
About SSOS
Space Station OS (SSOS) is an open-source ROS2 platform designed to unify the development and simulation of space station subsystems - guidance and control (GNC), power (EPS), thermal, communications, and life support (ECLSS).
It is built around modular software architecture and simulation-first development principles. Our goal is to accelerate prototyping, testing, and integration of complex spacecraft systems, with a clear path from simulation to hardware.
Even if you’re not working on space systems, the challenges overlap heavily with mobile robotics, autonomous platforms, and modular simulation - so your skills are highly relevant.
How to get involved
We welcome collaboration and discussion, especially in the following areas:
- Mechatronics and physical modeling
- Autonomous control and planning
- ROS2-based architecture and integration
- SILS/HILS development
- Environmental systems and closed-loop simulation
- Data handling and visualization for robotic platforms
