GPS ToolBox

Version 4.01 GPS Toolbox is a library of MATLAB m-file modules and programs used for the implementation of GPS applications. It enables the user to simulate a specific GPS application quickly and easily without the need to code and test the basic GPS algorithms.

Due to the fact that this software tool is primarily addressed to a practicing engineer, effort was made to implement the most efficient algorithms available in the technical literature. When appropriate, more than one module performs the same mathematical computation by using different methods, so you can select the approach that best meets your specific requirements.

The MATLAB GPS Toolbox contains numerous main programs which can be modified to fit specific application needs. Once the model of the application is derived or selected, the practitioner can use the software library to implement and test the validity of the proposed GPS application.

All of the more than 200 m-files are compatible with MATLAB 5.0 and higher, and most are also compatible with previous versions and Student Editions of MATLAB.

There are more than 31 fully explained examples (more than 80 pages) with input and output data and plots. Overall, the User's Guide and Reference Manual has more than 200 pages.

The source code is royalty free. The user can incorporate this software into applications, but is not permitted to resell the software "as is" or with changes.
