Research and Simulation on the Algorithm of Guided Projectile Strapdown Inertial Navigation System

Abstract:

To improve the hit probability and damage probability of guided projectile, made the strapdown inertial navigation technology better application in guided projectile, based on the feature of short range and short flying time of guided projectile, a simplification model of SINS (strapdown inertial navigation system) was proposed. The optimal 3-subsample rotation vector simulation platform was founded based on the tradition method, and this system was also checked by simulation using three-channel databases from simulator testing. The results show that this system not only can satisfy the requirement of real-time and precision, but also can improve the relative error to 10-6. The influence of direction draft to the guided projectile is also reduced.
