Autonomy, of concealment and navigation information completeness and inertial navigation system-specific features, which determines the special position of the inertial navigation system in military applications , precision-guided laser SINS technology to improve our weapons from a crucial role . Laser SINS optimization algorithm to meet the precision-guided weapons platforms ( aircraft) , in order to improve the overall accuracy of the laser SINS system , in-depth research . The main research work is concentrated in the algorithm, algorithm derivation and simulation , specifically: a brief INS theoretical basis . To define some common parameters , the definition of a vector cross product , the Coriolis theorem to derive the coordinate transformation , the basic equation illustrates some of the symbol conventions . 2 , the laser SINS algorithm in-depth , accurate derivation . Study the following algorithm: attitude update the quaternion algorithm to calculate the rotation vector algorithm ; cone motion environment , rotation vector sub-sample solution and the algorithm drift and optimization algorithms ; the speed algorithm paddling effect compensation algorithm and optimization algorithm ; the rotation effect compensation algorithm in the location algorithm , the the scroll effect compensation algorithm and optimization algorithm . Detailed derivation and expand the navigation parameters and the great circle route track solver algorithm , we also give the algorithm flow chart . 4, the laser SINS optimized route planning algorithm and the great circle route to all-digital simulation . The course of the study , data collection, analysis , induction, mathematics, mechanism of derivation , simulation method . From the simulation results can be seen after optimization algorithm solver attitude accuracy of the angle of the order of scores , the position accuracy Damien order of magnitude ( 1000s ) . The innovation of this thesis are: 1, laser SINS attitude , speed, position solver optimization algorithm . 2, the proposed extension of the navigation parameters and the great circle route track solver algorithm . 3 , the laser SINS programming optimization algorithm and the great circle route route planning all-digital simulation .
