New 2017 Toolbox Release!
We are happy to announce the 2017.1 release of the Spacecraft Control Toolbox. Follow the link above for the changelist.

Design • Analyze • Simulate

The Spacecraft Control Toolbox (SCT) for MATLAB® lets you design, analyze and simulate spacecraft. This product is used worldwide by leading research and development organizations and spacecraft manufacturers. Over two thousand functions are provided for attitude and orbit dynamics, simulation, analysis and design. You can build a satellite using the graphical CAD tools; design and analyze the control systems; perform disturbance analyses and test the control system in a six degree-of-freedom simulation - all in the MATLAB environment. The toolbox is provided with full source code for every function, nothing is hidden!

Proven in Flight

Princeton Satellite Systems has used this toolbox over the past 15 years to design the complete Indostar/Cakrawarta-1 transfer and geosynchronous attitude control systems; the TDRS momentum management system; formation flying systems for NASA/GSFC and on many other projects. Many of the tools are the product of our own research and development and are not available anywhere else!

Extensive documentation is included such as our 500 page theory textbook, Spacecraft Attitude and Orbit Control. The User's Guides can be downloaded for free from the product pages or below.

Toolbox Editions and Related Products

Which toolbox edition is right for you? Our Comparison Table [PDF] provides details about the differences between our spacecraft toolbox products.

The toolbox is available in three editions: Professional, Academic, and CubeSat. The Pro Edition provides comprehensive software and extensive examples for designing any spacecraft control system, anywhere in the solar system. Add-on modules are available to the Pro Edition for formation flying, fusion propulsion, launch vehicles, solar sails, and spin-axis attitude determination in a transfer orbit. The Academic Edition is a subset of the Pro software that is intended for undergraduate and graduate level attitude control system design and analysis. The CubeSat Toolbox is our entry level product that has been specially designed for CubeSat teams. Click on the product names in the table below to navigate to the relevant pages.
