Initial alignment for strapdown inertial navigation system based on inertial frame

2009 International Conference on Mechatronics and Automation, 2009
A 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), 2017
The 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

2004
The 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), 2017
The 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

A misalignment angle error calibration method of underwater acoustic array in strapdown inertial navigation system/ultrashort baseline integrated navigation system based on single transponder mode.

Review of Scientific Instruments, 2019
The angle misalignment error of a USBL (Ultrashort Baseline) acoustic array is one of the major error sources of the strapdown inertial navigation system/USBL positioning system, which will directly affect the positioning accuracy of the USBL positioning

Equivalent nonlinear error models of strapdown inertial navigation system

Guidance, Navigation, and Control Conference, 1997
The 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
