Initial alignment for strapdown inertial navigation system based on inertial frame
2009 International Conference on Mechatronics and Automation, 2009A 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

Identification modeling of inertial sensors' parameters of strapdown inertial navigation systems
2017 2nd International Ural Conference on Measurements (UralCon), 2017The 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.

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.

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

Equivalent nonlinear error models of strapdown inertial navigation system
Guidance, Navigation, and Control Conference, 1997The conventional linearized error models of strapdown inertial navigation system( SDINS ) are found not to be effective to represent the nonlinear characteristics of navigation error propagation in case of the system which causes the large navigation errors. To represent the large attitude error of the SDINS, the rotation vector error is introduced and

Optimal Two-Position Alignment for Strapdown Inertial Navigation System
2008 International Conference on Intelligent Computation Technology and Automation (ICICTA), 2008The optimal two-position alignment using Kalman filter is newly derived for strapdown inertial navigation system (SINS). During the alignment process, SINS is rotated with respect to the heading axis. The Kalman filter estimates the misalignments and gyro drifts at these two positions.

Strapdown inertial navigation system requirements imposed by synthetic aperture radar
Journal of Guidance, Control, and Dynamics, 1985The purpose of this paper is to demonstrate a means of specifying strapdown inertial navigation system (INS) requirements from synthetic aperture radar (SAR) requirements. The latter include allowable levels for quadratic and cubic phase shift, and side lobe levels [i.e., peak side lobe ratio (PSLR) and integrated side lobe ratio (ISLR)].

In-Motion Alignment Algorithm of Strapdown Inertial Navigation Systems
2018 DGON Inertial Sensors and Systems (ISS), 2018Strapdown Inertial Navigation Systems (SINS) estimate position, velocity and angular orientation upon signals acquired by inertial sensors– accelerometers and gyroscopes - stiffly fixed on a vehicle. A SINS begins operating by the initialization process which provides initial position, velocity and alignment.

Strapdown inertial navigation systems based on fiber-optic gyroscopes
Gyroscopy and Navigation, 2014Strapdown inertial navigation systems (SINS) are basic parts of modern integrated navigation systems in various vehicles. Currently, fiber-optic gyroscopes (FOGs) with closed-loop feedback are finding increasing use for inertial navigation systems.
