Navigation Computation in Terrestrial Strapdown Inertial Navigation Systems
IEEE Transactions on Aerospace and Electronic Systems, 1977The problem of computing the translational velocity and position relative to earth, which has to be solved by the processor of a strapdown inertial navigation system is discussed. Several approaches are briefly examined with consideration given to the form in which the sensor data are generated and to the computational burden involved in each approach.

Initial Alignment by Attitude Estimation for Strapdown Inertial Navigation Systems
IEEE Transactions on Instrumentation and Measurement, 2015This paper derives a novel initial alignment method for the strapdown inertial navigation system (SINS), which transforms the attitude alignment into an attitude estimation problem. The process model of the proposed initial alignment method by attitude estimation is established by decomposition of the attitude matrix.

In-Motion Filter-QUEST Alignment for Strapdown Inertial Navigation Systems
IEEE Transactions on Instrumentation and Measurement, 2018By 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 pendulum type
Mechanics of Solids, 2014We 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.

Strapdown inertial navigation system of a rotating carrier
2017 24th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS), 2017The 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

Analysis of the Symmetry for a Rotating Strapdown Inertial Navigation System
Advanced Materials Research, 2012It is known that the precision of the strapdown inertial navigation system is influenced by constant bias of inertial sensors. A method of self-compensation based on a rotating inertial navigation system is proposed to enhance the precision. The constant drift of gyro and accelerometers is modulated into a seasonal and zero-mean form. In the paper, the

Application of Neural Network to the Alignment of Strapdown Inertial Navigation System
2007In 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

Research on the dynamic error of strapdown inertial navigation system
2008 IEEE International Conference on Mechatronics and Automation, 2008Researching on the static error of strapdown inertial navigation system (SINS) plays a great role in the past. This is mainly due to the complex mathematical model for dynamic error of SINS. It is hard to do the error analysis from the perspective of the number.
