The CubeSat Toolbox for MATLAB® is an educational product for designing CubeSats and analyzing typical CubeSat missions. The toolbox consists of the CubeSat module from the Spacecraft Control Toolbox with a subset of functions from the core toolbox; the Spacecraft Control Toolbox is not required. Please see the API, our comparison table [pdf], and the Getting Started [pdf] guide for more information. Scroll down to purchase online.
The CubeSat Toolbox is applicable to any small satellite project.
- Trade studies.
- Control system design.
- CubeSat mission planning.
- Communications link analysis.
- Stability analysis of gravity gradient and passive magnetic satellites.
- Power and thermal analysis.
- Orbit modeling and simulation.
- Disturbance modeling.
- Generate attitude profiles with sequences of primary and secondary alignments.
- Relative orbit simulations and coordinate transformations.
The license for the CubeSat toolbox is for an entire university CubeSat or nanosatellite team. Up to 10 users may register for technical support. To register users you must send Princeton Satellite Systems a list of user’s names and their university email addresses. Gmail, etc. addresses will not be accepted. If purchased for commercial use than the license is per user as with our other toolboxes.
Our software license is perpetual and includes complete source code. All PSS products include 90 days of free telephone support and one year of free email technical support and product updates. Annual maintenance fees provide software updates and additional technical support. For complete details, refer to the Software License Agreement.
