Abstract Initial alignment is the precondition for strapdown inertial navigation system
(SINS) to navigate. Its two important indexes are accuracy and rapidity, the accuracy of
the initial alignment is directly related to the working accuracy of SINS, but in selfalignment, the two indexes are often contradictory. In view of the limitations of
conventional data processing algorithms, a novel method of compass alignment based on
stored data and repeated navigation calculation for SINS is proposed. By means of data
storage, the same data is used in different stages of the initial alignment, which is
beneficial to shorten the initial alignment time and… More >
