Add-On Modules

Formation Flying

This module provides dynamics, control, and estimation support for formations of satellites. Circular and eccentric orbits are supported. The module features a decentralized formation flying (DFF) control system developed via SBIRs for NASA Goddard Space Flight Center.

Fusion Propulsion

This module provides a complete, integrated set of tools needed to perform the design and analysis of nuclear fusion propulsion systems. It includes functions for nuclear fusion power generation, nuclear fusion physics and propulsion. It has a complete set of functions for point reactor designs. All fusion reactions including Deuterium-Tritium, Deuterium-Helium 3 and Boron Proton can be analyzed. Additional functions provide tools for sizing shielding and cyrogenic cooling systems.

Solar Sail

This module’s high-fidelity disturbance model enables users to simulate complex solar sail shapes without resorting to analytical approximations. You can study the nonlinear effects of different sail material properties and propellantless actuation schemes. The combination of these special sail CAD and dynamics models with control design tools from the core toolbox provide a complete sail attitude and orbit control analysis solution!

Spin Axis Attitude Determination

This module provides a complete, integrated set of tools needed to perform spin-axis attitude determination using horizon sensor and sun sensor measurements. Spin-axis attitude determination requires at least one horizon sensor and one single-axis sun sensor.
