Gyrocompassing mode of the strapdown inertial navigation system
2017 IEEE 2nd Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2017A gyrocompassing mode of the strapdown inertial navigation systems (SINS) was presented. SINS has been composed of Inertial Measurement Unit (IMU) and navigation computer. IMU consists of triad accelerometers, gyroscopes and a circuit of signal processing.

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.

System reset for underwater strapdown inertial navigation system
Ocean Engineering, 2019Abstract Conventional system reset methods establish the relationship between measurements such as position or heading and gyro drifts by the Psi equation, following which, they iteratively calculate the gyro drifts. However, these methods have some limitations in practice.

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.

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.

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.

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.
