MIT's spacecraft simulator for control algorithm development
The SPHERES simulation is designed to support most software-related aspects of single- and multi-satellite SPHERES operations. The simulation code base consists of simulated versions of most of the SPHERES core flight code and additional code that simulates dynamics, communications, and other environmental interaction.
The simulation is particularly valuable during the early stages of algorithm development and implementation as an aid in accelerating the learning curve for any Guest...
The Dutchroll project provides Open Source applications for Matlab and Simulink, with the emphasis on aerospace engineering. The main application is the Flight Dynamics and Control toolbox; other applications will be derived from that toolbox.
