MEMS-based rotary strapdown inertial navigation system

Measurement, 2013
Abstract As the inertial navigation completely depends on the sensed acceleration and rotation rate by IMU, the sensor errors accumulate and eventually lead to diverged inertial solutions. Therefore the compensation of the inertial sensor errors is an effective approach to improve the SINS navigation performance.

Strapdown inertial navigation algorithm in geometric algebra

2011 International Conference on Electrical and Control Engineering, 2011
Geometric algebra(GA) is a very convenient representational and computational system for geometry due to its clear geometrical meanings and simple notations. The rigid body motion is represented by motors in GA. We derive the kinematic equation of motors, and associate motors with specific force acceleration and angular rate which can be measured in ...

Study of strapdown inertial navigation integration algorithms

2004 International Conference on Intelligent Mechatronics and Automation, 2004. Proceedings., 2005
This paper proposes an approach to update the attitude and velocity synchronously utilizing the fourth order Runge-Kutta in the strapdown inertial navigation system. The synchro-updating algorithm is designed for the condition, in which the outputs of gyroscope are the angular rate and the outputs of accelerometer are the specific force acceleration ...

Navigation Computation in Terrestrial Strapdown Inertial Navigation Systems

IEEE Transactions on Aerospace and Electronic Systems, 1977
The 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.

Improvement of strapdown inertial navigation using PDAF

IEEE Transactions on Aerospace and Electronic Systems, 1999
A new application of PDAF (probabilistic data association filter) for improving the accuracy of autonomous strapdown inertial navigation systems (SINS) is presented. The proposed method is a terrain-aided navigation (TAN) algorithm based on landmark detection combined with a classical SINS.

Strapdown Inertial Navigation Algorithms Based on Lie Group

Journal of Navigation, 2016
This paper presents a framework for a strapdown Inertial Navigation System (INS) algorithm design by using Lie group and Lie algebra. The general way to solve Lie group differential equations is introduced. Investigations reveal that this general Lie group method provides a simpler unified way to solve differential equations involving direction cosine ...

Doppler-Aided Low-Accuracy Strapdown Inertial Navigation System

Journal of Guidance, Control, and Dynamics, 1982
This paper presents a covariance analysis of the performance of a Doppler-aided low-accuracy coarsely aligned strapdown inertial navigation system (INS), whose fine alignment takes place automatically in flight. It is shown that the fine alignment in azimuth, which requires turns, consists of in-flight gyro calibration and inflight gyrocompassing.

Navigation schemes for underwater robots using strapdown inertial navigation system

Proceedings IECON '91: 1991 International Conference on Industrial Electronics, Control and Instrumentation, 2002
The authors deals with navigation schemes for underwater robots using strapdown inertial navigation systems. Compared to the current hydroacoustic position reference systems used for underwater robots, the strapdown inertial systems have longer operation distance, possess better autonomous ability, provide more complete navigation, and offer higher ...
