Application of Kalman filtering technique to initial axes alignment of SDINS

SDINS의 좌표축 초기 배열에 관한 칼만 필터링 기법의 응용

Initial alignment of gimballed INS is accomplished by the gyrocompassing techniques. These cannot be used in the case of strapdown system where the inertial instruments are directly strapped down to a vehicle frame. The basic objective of this paper is the development of digital methods performing the initial alignment of a SDINS from vibration and sway currupted data on the launch pad.
