| Abstract: | Focused on the ballistic missile using inertial guidance,the calculation and compensation for instrument error of rate strapdown inertial navigation system was researched. The mathematical model of inertial measuring and instrument error was established,the compensation formula of instrument error for accelerometer and gyroscope was deduced,and simulation calculation was conducted. On basis of simulation results,the effect of instrument error coefficient deviation on the impact point deviation was analyzed,... |
