 # GINav
-NOTE: The program is still under development, and some bugs may exist in GINav. Comments and suggestions from users are welcome, please send them to the author ([email protected]). Additionally, we will further optimize GNSS/INS integration algorithms and develop a C language-based GINav. If you're interested in the GINav algorithm, you can join the GINav discussion group (`QQ:533185090`) <br>

 ## Introduction <br>
 GINav is an open-source software, which focuses on the data processing and analysis of GNSS/INS integrated Navigation system, and can also process multi-constellation and multi-frequency GNSS data. GINav is suitable for in-vehicle situations and is aimed at providing a useful tool for carrying out GNSS/INS-related research. It is a convenient platform for testing new algorithms and experimental functionalities. GINav is developed in MATLAB environment. It provides a user-friendly graphical user interface (GUI) to facilitate users to learn how to use it quickly. A visualization tool, GINavPlot, is provided for solution presentation and error analysis.  <br>
