| What's Included |
 |
The Launch Vehicle Toolbox (LVT) is composed of MATLAB m-files and mat-files, organized into a set of modules by subject. It is essentially a library of functions for analyzing vehicles and missions. The Launch Vehicle Toolbox is a combination of the Spacecraft Control Toolbox and the Aircraft Control Toolbox, as well as a unique Add-On module (LaunchVehicle) that uses functions from both of these two stand alone toolboxes.
The core spacecraft files are in SC and SCPro which also include special CAD models. The core aircraft files are in AC and ACPro which again also include special CAD models. Princeton Satellite Systems has also developed companion plotting tools to go in addition to Matlab's built in plotting functions. These plotting tools are organized in the Plotting module. Functions for estimation, orbit analysis, subsystem analysis, and detailed attitude control system examples are grouped in separate modules.
All of the modules are described in the following table. Note that if you have downloaded the Aircraft Control Toolbox and the Spacecraft Control Toolbox separately, you only need to retain one copy of Common.
