Code Optimization for Strapdown Inertial Navigation System Algorithm [PDF]
, 2018 Inertial navigation systems are in common use for decades due to its advantages. Since INS outputs are usually used for inputs in different control algorithms (depending on applications), INS will induce certain errors and limitations. This chapter deals with optimization of the inertial navigation algorithm against limitations due to the accuracy and ...

A Novel Damping Method for Strapdown Inertial Navigation System [PDF]
IEEE Access, 2019 <p> </p> <p>There are periodic oscillation errors in the strapdown inertial navigation system (SINS) when it works in pure inertial navigation mode. It seriously restricts the navigation accuracy of the system. In order to improve the accuracy of the system, the traditional idea of the external horizontal damping in the stabilized ...

An Improved Alignment Method for the Strapdown Inertial Navigation System (SINS) [PDF]
Sensors, 2016 In this paper, an innovative inertial navigation system (INS) mechanization and the associated Kalman filter (KF) are developed to implement a fine alignment for the strapdown INS (SINS) on stationary base. The improved mechanization is established in the pseudo-geographic frame, which is rebuilt based on the initial position.

Optimization-based alignment for strapdown inertial navigation system: comparison and extension [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2016 In this paper, the optimization-based alignment (OBA) methods are investigated with main focus on the vector observations construction procedures for the strapdown inertial navigation system (SINS). The contributions of this study are twofold. First the OBA method is extended to be able to estimate the gyroscopes biases coupled with the attitude based ...
