Improvement of strapdown inertial navigation using PDAF
IEEE Transactions on Aerospace and Electronic Systems, 1999A new application of PDAF (probabilistic data association filter) for improving the accuracy of autonomous strapdown inertial navigation systems (SINS) is presented. The proposed method is a terrain-aided navigation (TAN) algorithm based on landmark detection combined with a classical SINS.

A New Mathematical Formulation for Strapdown Inertial Navigation
IEEE Transactions on Aerospace and Electronic Systems, 1971A differential equation is developed for the orientation vector relating the body frame to a chosen reference frame. The time derivative of this vector is the sum of the inertially measurable angular velocity vector and of the inertially nonmeasurable noncommutativity rate vector.

Correction of a Strapdown Inertial Navigation System During Descent in the Atmosphere
Mechanics of Solids, 2023The article deals with the problem on determining the angular position during descent on an apparatus with low lift-drag ratio. A solution is presented using the least squares method, which reduces to determining the orientation quaternion using a system of linear algebraic equations.

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.

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.

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 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

Basic principles of strapdown inertial navigation systems
2004The previous chapter has provided some insight into the basic measurements that are necessary for inertial navigation. For the purposes of the ensuing discussion, it is assumed that measurements of specific force and angular rate are available along and about axes which are mutually perpendicular.
