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

Application of Neural Network to the Alignment of Strapdown Inertial Navigation System

2007
In this paper, a strapdown inertial navigation system (SINS) error model is introduced, and the model observability is analyzed. Due to the weak observability of SINS error model, the azimuth error can not be estimated quickly by Kalman filter. To reduce the initial alignment time, a neural network method for the initial alignment of SINS on stationary

Research on the dynamic error of strapdown inertial navigation system

2008 IEEE International Conference on Mechatronics and Automation, 2008
Researching on the static error of strapdown inertial navigation system (SINS) plays a great role in the past. This is mainly due to the complex mathematical model for dynamic error of SINS. It is hard to do the error analysis from the perspective of the number.

Analysis of the Symmetry for a Rotating Strapdown Inertial Navigation System

Advanced Materials Research, 2012
It is known that the precision of the strapdown inertial navigation system is influenced by constant bias of inertial sensors. A method of self-compensation based on a rotating inertial navigation system is proposed to enhance the precision. The constant drift of gyro and accelerometers is modulated into a seasonal and zero-mean form. In the paper, the

Terrain-Aided Strapdown Inertial Navigation System with Improved ICCP

2018
Ocean exploration is playing an increasingly significant role in the development of each country because of the huge material resources therein. A terrain-aided strapdown inertial navigation system based on Kalman Filter (KF) is proposed in this paper in order to improve the navigation precision of autonomous underwater vehicles. The characteristics of

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.

Research on the Vibration Control for Strapdown Inertial Navigation System

2010 Second International Conference on Intelligent Human-Machine Systems and Cybernetics, 2010
This paper investigates the vibration control for strap down inertial navigation system (SINS) based on the theoretical analysis and the simulation confirmation. Firstly, the disadvantage of passive vibration control technique commonly used for SINS at present is pointed out that it is only effective at high frequency.

A strapdown inertial navigation system for the flat-Earth model

IEEE Transactions on Aerospace and Electronic Systems, 1997
The development of a strapdown inertial navigation system (SINS) for aerodynamically controlled vehicles, which are limited to altitudes below 30 km (that is, a small distance compared with the Earth's radius of about 7000 km), or using the so-called flat-Earth model (FEM), is the principal objective of this work. In dealing with the FEM equations, the

In-Motion Alignment Algorithm of Strapdown Inertial Navigation Systems

2018 DGON Inertial Sensors and Systems (ISS), 2018
Strapdown 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.
