The GPS Toolbox is a topical collection dedicated to highlighting algorithms and source code utilized by GNSS engineers and scientists. 09. REFL_CODE = where the reflection code file (SNR files and results) will be stored. INS MATLAB Toolbox to emulate inertial sensors from RGLs and FOGs and MEMS. The toolbox provides a nonlinear six-degrees-of-freedom (6DOF) flight profile and trajectory generator and a land vehicle trajectory generator, as well as a simple point-mass model.
