Bench calibration problem for a strapdown inertial navigation system
Mechanics of Solids, 2009We solve the bench calibration problem for a strapdown inertial navigation system. A distinguishing characteristic of the calibration algorithm under study is that the information conveyed by the bench transducers is not used directly. We study how the calibration accuracy depends on the program rotations performed by the bench platform control.

Strapdown inertial navigation system calibration
2017 2nd International Ural Conference on Measurements (UralCon), 2017The paper aims at improving the accuracy of the calibration of strapdown inertial navigation systems (SINS). The calibration is carried out using a 2-axial motion simulator. A new computational method is investigated for the calibration coefficients of the error models of accelerometers and gyroscopes of the strapdown inertial navigation system based ...

A methodological use of inertial navigation systems for strapdown navigation task
2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017This paper presents a study of mathematical description for inertial navigation systems and integration of virtual sensors implementation. Virtual sensors allow to estimate quantities detecting events or changes in its environment, to calculate variables such velocity, position and attitude on rigid or mobile bodies of navigation systems. Recently, the

Multiposition alignment of strapdown inertial navigation system
IEEE Transactions on Aerospace and Electronic Systems, 1993The authors demonstrate that the stationary alignment of strapdown inertial navigation system (SDINS) can be improved by employing the multiposition/technique. Using an observability analysis, it is shown that an optimal two-position alignment not only satisfies complete observability conditions but also minimizes alignment errors.

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.

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.

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.
