Strapdown inertial navigation system of pendulum type

Mechanics of Solids, 2014
We consider two implementations of an isotropic oscillator to be used in the construction of a strapdown inertial system of new type [1]. The first implementation is a contact-free suspension of an electrically conductive ball used in electrostatic gyros, and the second implementation is a 3D combination of elastic constraints holding a mass point.

In-Motion Filter-QUEST Alignment for Strapdown Inertial Navigation Systems

IEEE Transactions on Instrumentation and Measurement, 2018
By analyzing the error models of the measured vectors of the gravitational apparent motion, an in-motion filter-QUEST alignment method only with the inertial measurement unit is presented in this paper. The contribution of the proposed method lies in constructing the in-motion model of the measured vectors of the gravitational apparent motion and ...

Strapdown inertial navigation system of a rotating carrier

2017 24th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS), 2017
The paper deals with a strapdown inertial navigation system (SINS) of a rotating carrier (RC) characterized by a high roll speed and rather slow oscillations in the yaw and pitch angles. It is shown that it is expedient for an RC to develop four orientation parameters: traditional yaw angles, pitch and trigonometric functions of the sine, cosine of the

Identification modeling of inertial sensors' parameters of strapdown inertial navigation systems

2017 2nd International Ural Conference on Measurements (UralCon), 2017
The paper aims at improving the accuracy of the strapdown inertial navigation systems (SINS). The calibration is carried out using a 2-axial motion simulator. The influence of motion simulator instrumental errors is investigated. They effect the errors in the determination of calibration coefficients for SINS accelerometers and gyroscopes.

Initial alignment for strapdown inertial navigation system based on inertial frame

2009 International Conference on Mechatronics and Automation, 2009
A initial alignment algorithm in the inertial frame based on the alignment application of Kalman filter was presented. State and observation equations of strapdown inertial navigation system (SINS) are established using Kalman filter by the gravity vector projected in the inertial frame, and the initial alignment of the SINS based on the inertial frame

Application of Neural Network to the Alignment of Strapdown Inertial Navigation System

2007
In this paper, a strapdown inertial navigation system (SINS) error model is introduced, and the model observability is analyzed. Due to the weak observability of SINS error model, the azimuth error can not be estimated quickly by Kalman filter. To reduce the initial alignment time, a neural network method for the initial alignment of SINS on stationary

Strapdown Inertial Navigation Algorithms Based on Lie Group

Journal of Navigation, 2016
This paper presents a framework for a strapdown Inertial Navigation System (INS) algorithm design by using Lie group and Lie algebra. The general way to solve Lie group differential equations is introduced. Investigations reveal that this general Lie group method provides a simpler unified way to solve differential equations involving direction cosine ...
