Strapdown Inertial Navigation Simulation Program

This article provides a detailed description of the Strapdown Inertial Navigation Simulation Program. This program serves as a simulation system that evaluates the performance of actual navigation systems through position, velocity, and acceleration modeling. The simulation architecture is divided into multiple modules, including sensor modules, control modules, and output modules. The sensor module implements algorithms to detect aircraft parameters such as position, velocity, and acceleration - typically using inertial measurement unit (IMU) data processing techniques. The control module employs navigation algorithms (like Kalman filtering or dead reckoning) to compute optimal flight trajectories based on these parameters. The output module visualizes simulation results through graphical interfaces or data export functions. To ensure simulation accuracy, the mathematical models and algorithms within each module require precise calibration and optimization, involving parameter tuning and validation against reference trajectories.
