Genetic Algorithm-Particle Swarm Optimization algorithm based Compass Initial Alignment of Strapdown Inertial Navigation System

2018 IEEE CSAA Guidance, Navigation and Control Conference (CGNCC), 2018
The rapidity and accuracy of the initial alignment influence the performance of the Strapdown Inertial Navigation System (SINS), compass alignment is one of the most important methods for initial alignment. The selection of the parameters of the compass alignment loop directly affects the result of alignment. Nevertheless, the optimal parameters of the

Robust self-corrective initial alignment algorithm for strap-down INS

2015 10th Asian Control Conference (ASCC), 2015
This paper presents a novel robust method of self-corrective Initial Alignment of a stationary SINS1 with respect to local-level frame (NED-frame) depending only on the output of a strap-down IMU2. The proposed method provides a superior performance compared to traditionally-known self-corrective initial alignment methods. The main contribution of this

Research on the Algorithm of Initial Alignment for New Generation Air-to-air Missile

2020 Chinese Control And Decision Conference (CCDC), 2020
As one of the main weapons of the fourth generation fighter, the new generation air to air missile has the characteristics of close combat and over sight air interception, which determines that the transfer alignment of the missile borne moving base must be full of rapidity and high precision. In view of this, the mainly research content of this report

A novel initial alignment algorithm based on the interacting multiple model and the Huber methods

2016 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2016
Initial alignment is one of the key technologies in Strapdown inertial navigation system (SINS). It is divided into coarse alignment and fine alignment. The conventional method of fine alignment is to adopt Kalman filtering and uses single filter to estimate system states. In Kalman filtering, it is known that system model should be matched with actual

Initial Alignment Algorithm Study Based on Rotating Modulation and Kalman Filtering

Applied Mechanics and Materials, 2014
Kalman filtering is used to restrain the influence of environmental disturbance to the initial alignment precision. Meanwhile, rotating modulation is utilized to reduce the influence of peg-top excursion and accelerometer zero deflection. The theoretical analysis and test data demonstrate that the proposed algorithm can improve the alignment precision ...

An In-Motion Initial Alignment Algorithm for SINS Using Adaptive Lie Group Filter

2018 37th Chinese Control Conference (CCC), 2018
In this paper, an in-motion initial alignment algorithm based on Lie group is proposed, which effectively solves the non-uniqueness of the unit-quaternion attitude description and the nonlinear problem when using unit-quaternion for state estimation. The algorithm divides the attitude matrix into three successive special orthogonal matrices according ...
