In the process of inertial alignment for an strapdowm inertial navigation system(SINS) on stationary base , the azimuth error’s poor observability leads to its long alignment time . In order to solve the problem,the paper considers inertial alignment as an optimizing process with the application of improved artificial fish swarm algorithm.Simulation ...

Attitude algorithm and initial alignment method for SINS applied in short-range aircraft
Modern Physics Letters B, 2017This paper presents an attitude solution algorithm based on the Micro-Electro-Mechanical System and quaternion method. We completed the numerical calculation and engineering practice by adopting fourth-order Runge–Kutta algorithm in the digital signal processor.

A novel initial alignment algorithm of SINS/GPS on stationary base with attitude measurement
2011 International Conference on Electronics, Communications and Control (ICECC), 2011Based on the error model of SINS/GPS and viewed of the improving of the observability and the observability degree, a novel initial alignment algorithm of SINS/GPS on stationary base with attitude measurement is put forward, which uses both the velocity error and yaw error as the observational value of Kalman filter.

A New Initial Alignment Algorithm for Strapdown Inertial Navigation System Using Sensor Output
IFAC Proceedings Volumes, 2008Abstract In this paper, a new alignment algorithm that uses simultaneously both open-loop and closed-loop scheme is designed to increase the convergence rate of the Kalman filter in the fine alignment stage. Generally, the initial alignment is divided into coarse and fine alignment. The fine alignment stage with the 10-state Kalman filter refines the

Application of Sage-Husa adaptive filtering algorithm for high precision SINS initial alignment
2014 11th International Computer Conference on Wavelet Actiev Media Technology and Information Processing(ICCWAMTIP), 2014When the system model and noise statistical characteristics are known, the conventional Kalman filtering algorithm is suitable. In most cases, the noise statistics are unknown. To improve the alignment precision and convergence speed of strap-down inertial navigation system, an initial alignment method based on Sage-Husa adaptive filter is proposed ...
