MATLAB and Simulink provide aerospace engineers with capabilities that speed the development process and improve communication between teams. You can use MATLAB and Simulink to:
- Perform requirements-based mission validation in the time domain
- Run system-level Monte-Carlo simulations using multi-discipline spacecraft models
- Conduct trade studies for spacecraft sizing and hardware selection
- Analyze spacecraft telemetry and payload data
- Design detailed guidance, navigation, and control (GNC) algorithms
- Model Photo-Voltaic (PV) power subsystems and design power electronics components
- Analyze RF and digital communications subsystems and deploy the algorithms on FPGAs
- Generate embedded C and C++ code following space industry standards
- Perform flight software verification and validation
"MATLAB enabled our team to accelerate the development and debugging of highly accurate OpNav algorithms. On the OSIRIS-REx mission, for example, the center-finding algorithms were accurate to within 30 centimeters, or about 0.06% of the asteroid’s diameter—significantly outperforming the predicted accuracy of the mission’s navigation Concept of Operations (ConOps)."

Guidance, Navigation, and Control (GNC)
Using MATLAB and Simulink, you can test your control algorithms with plant models before implementation to achieve complex designs without using expensive prototypes. You can design for multiple physical configurations, such as the common bus architecture of a satellite design. In a single environment, you can work on:
- Building and sharing GNC models
- Integrating and simulating system-level effects of controls and mechanical design changes
- Reusing automatically generated flight code and test cases
- Integrating new designs with legacy designs and tools
Power Systems
You can use MATLAB and Simulink for tasks like running simulations for mission power profile analysis, predicting the system impacts of battery aging, and performing detailed design of electrical components such as DC-DC converters.
MATLAB and Simulink let you rapidly model electrical components and systems, such as solar arrays and voltage regulators, using provided blocks, or create custom blocks where the design calls for it. You can then simulate your model to solve the underlying complex systems of equations without writing low-level code, and immediately visualize the results. You can also include thermal and attitude effects in your models to perform multidomain simulation within one environment.
Communications Systems
You can use MATLAB and Simulink as a common design environment to develop, analyze, and implement spacecraft communications systems. You can model and visualize satellite orbits, and perform link analysis and access calculations. MATLAB and Simulink help you prototype signal chain elements—including RF, antenna, and digital elements—and combine the work of multiple teams as a system-level executable model.
You can explore imperfections at the system level and examine what-if scenarios that are difficult to produce in the lab. As the design matures, you can automatically generate C code for embedded processors or HDL code for FPGAs.
Systems Engineering
System Composer enables you to create space and ground system architectures, define interfaces, and perform trade studies to evaluate your designs. You can trace between levels of requirements and architectures and perform requirements allocation.
You can insert executable models into the architecture with MATLAB and Simulink to propagate and visualize satellite and constellation orbits and perform mission analysis such as computing line-of-sight-access. Also, you can add fidelity to the underlying system behaviors with executable multidomain spacecraft and ground system models to verify and validate requirements, providing insights into system-level behavior and performance that cannot be obtained by static analysis alone.
As the system design progresses, you can further refine the architecture model by mapping requirements to test cases and automatically measuring requirements coverage as the test cases are executed. System Composer lets you trace between levels of requirements and architectures, monitor the detailed implementation of the requirements in the design, and track the requirements in the automatically generated source code. Also, you can create customized, automated reports for design documentation and testing.
Space Software Engineering
With MATLAB and Simulink, you can automate design workflows while maintaining compliance with various space standards. You can automatically generate and test C and C++ code from your models for both plant modeling and flight software. You can generate software reports and artifacts at each step, including design documents, metrics, and requirements.
