High Precision Dynamic Simulation Algorithm of Strapdown Inertial Navigation System

There are differences between the generation algorithm of vehicle dynamic model with the algorithm of inertial navigation system in scheduling principle.So the different error characteristics of inertial sensors can't analysis directly the affect of the dynamic performance of the inertial navigation system.Based aircraft dynamic models track data,we proposed a high-precision dynamic simulation method of SINS,which is the inertial navigation system dynamic parameter errors of the parallel compensation scheme to achieve effective separation of the dynamic simulation of the process of the inertial navigation system navigation parameters calculation error.Finally,we build the simulation platform of the ystem,which validate the performance of the method well.So it may be choosed to provide support for the actual selection of inertial sensors and indicators.
