Inertial navigation systems (INSs) are essential for modern aircraft, enabling accurate determination of position, attitude, and velocity without external references. This paper reviews the operational principles of INS, emphasizing the integration of gyroscope and accelerometer data, data flow within the system, and the importance of platform stabilization and alignment procedures. Key sources of error—such as sensor noise and platform instability—are identified, along with current strategies for error compensation and calibration. The evolution towards Inertial Reference Systems (IRS) is also discussed. By summarizing both theoretical foundations and practical considerations, this paper supports the development and maintenance of reliable INS solutions for aviation.
