Abstract This paper presents a method to improve the accuracy of and reduce the time needed for the initial alignment of strapdown inertial navigation systems. The new method is based on the conventional two position method enhanced by the use of gyro information. After presenting the problem of initial alignment and identifying the key issues – low accuracy and long convergence time, the paper introduces the two position method showing the improvement of performance but not on convergence time. By using gyro information in the new method, precision is improved and time for alignment reduced. The discussion is illustrated with simulations.
