Transfer Alignment Procedure for Inertial Navigation Systems

In both commercial and military aircraft, inertial navigation systems are essential for ensuring flight safety and maintaining correct flight paths. The transfer alignment procedure for inertial navigation is a widely used technique that combines velocity and attitude information to achieve precise aircraft positioning and navigation during flights. This process utilizes velocity and directional data from the inertial navigation system, integrated with attitude information from accelerometers and gyroscopes, to compute the aircraft's precise position and orientation. The implementation typically involves sensor fusion algorithms like Kalman filtering, which processes raw inertial measurements to estimate navigation states and correct alignment errors. Key functions include coordinate transformation calculations, quaternion-based attitude updates, and real-time data synchronization between master and slave navigation systems. This technology significantly enhances flight safety and navigation accuracy, enabling pilots to maintain better aircraft control and ensure smooth flight operations.
