A fast dynamic alignment method

The present invention is in alignment method, particularly relates to a rapid method for dynamic alignment. Comprising: Step one: coarse alignment; Step 1.1: input information; Step 1.2: Calculate ax, ay, az; Step 1.3: Calculate ωx, ωz Step 1.4: 1.5 calculation step: calculating step 1.6: Calculate Step two: navigation solution operator; step three: an intermediate variable calculation; step four: aligned. Advantageous effects of the invention are: the present invention at the carrier angular vibration can be estimated accurately based internet misalignment angle relative geographic three lines and three uncompensated drift of the platform (internet-based), so as to achieve high precision self-alignment purposes.
