Strapdown Inertial Navigation System Transfer Alignment: Algorithmic Features and Simulation Performance Analysis

The way of small aircraft strapdown inertial navigation system transfer alignment based on information from the carrier navigation system is considered. Optimal Kalman filter was selected as the main mathematical technique for the proposed method implementation, which showed acceptable accuracy and convergence time in the set task conditions. The main features of SINS transfer alignment algorithm and the results of its operation at complex trajectory simulation are presented.
