MATLAB source code for strapdown inertial navigation system simulation program, providing comprehensive understanding of strapdown INS principles with detailed algorithm implementation and key function descriptions
Strapdown Inertial Navigation Simulation Program. This simulation targets general aircraft applications, using the geographic coordinate system as the navigation frame. It implements mechanical arrangement and numerical simulation based on north-referenced navigation principles. The guidance system focuses on ballistic missiles, designing standard trajectories and comparing perturbation guidance with explicit guidance methods. The implementation selects flexible and adaptive explicit guidance, utilizing required velocity increment as the cutoff function to control engine shutdown for target impact.
