NaveGo: an open-source MATLAB/GNU-Octave toolbox for processing integrated navigation systems and performing inertial sensors profiling analysis. NaveGo is an open-source MATLAB/GNU Octave toolbox for processing integrated navigation systems, simulating inertial sensors and GPS receptor, and performing inertial sensors analysis that is freely available online. It is developed under MATLAB/GNU-Octave due to this programming language has become a de facto standard for simulation and mathematical computing. NaveGo has been verified by processing real-world data from a real trajectory and contrasting results with a commercial, closed-source software package. Difference between both solutions have shown to be negligible. For more information read (Gonzalez et al., 2017).
