Inertial Navigation System Simulation with SIMULINK Implementation

This document discusses inertial navigation system simulation programs and their application in the SIMULINK environment. An inertial navigation system (INS) is a technology that determines an object's position and orientation by measuring its linear acceleration and angular rates. The simulation program serves as a tool to replicate real-world scenarios, enabling comprehensive analysis and performance evaluation of INS systems. SIMULINK provides a powerful software environment for modeling and simulating dynamic systems, offering an intuitive graphical interface and extensive libraries for efficient simulation development. Through SIMULINK-based INS simulation development, engineers can implement core algorithms including: - Strapdown inertial navigation algorithms using integration techniques for position and velocity computation - Kalman filter implementations for sensor fusion and error estimation - Coordinate transformation modules handling navigation frame conversions - Sensor error modeling blocks simulating IMU imperfections The simulation environment allows parameter tuning, system optimization, and validation of navigation algorithms before actual implementation. This approach significantly enhances understanding of INS performance characteristics and improves system accuracy and reliability in practical applications. Key SIMULINK components typically include inertial measurement unit (IMU) blocks, navigation equations solvers, and visualization tools for trajectory analysis.
