Research on Independent Coarse Alignment of Aircraft Carriers SINS

Abstract:

Carrier-based Aircraft closely watched as the aircraft carrier weapons, storms and other factors affect the generated carrier swing to sway.This will enable the gyro measurement to the Earth's rotation angular velocity signal to noise ratio dropped significantly, giving the aircraft carrier's initialaligned to bring difficulties. To solve this problem, the Earth gravity acceleration in the inertial space the SINS independent coarse alignment, and gives the process of acceleration due to gravity points vector of analytic coarse alignment and fine alignment algorithm. Theoretical analysis and simulation results show that the moving base SINS alignment method can effectively solve the initial alignment of the aircraft carrier in the state of the ship mooring.
