A Navigation Accuracy Evaluation Method for Multi-path Platform Inertial Navigation System

Gyroscope Drift Error Analysis in the Position-Independent Navigation Algorithm of a stable platform Inertial System

This paper deals with analyzing gyroscope drift error in the position-independent navigation algorithm of a stable platform inertial system. Most of the stable platform navigation algorithms proposed in the literature have drawbacks of estimating position rates for alignment commands. Not only the estimating position rates are the basic source of position errors, but they also make the alignmen...

Extracting Dynamics Matrix of Alignment Process for a Gimbaled Inertial Navigation System Using Heuristic Dynamic Programming Method

In this paper, with the aim of estimating internal dynamics matrix of a gimbaled Inertial Navigation system (as a discrete Linear system), the discretetime Hamilton-Jacobi-Bellman (HJB) equation for optimal control has been extracted. Heuristic Dynamic Programming algorithm (HDP) for solving equation has been presented and then a neural network approximation for cost function and control input ...

Adaptive Fusion of Inertial Navigation System and Tracking Radar Data

Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...

Inertial Indoor Navigation System

This paper represents a first step in developing an indoor navigation system based only on Micro-Electro-Mechanical Systems (MEMS) accelerometer and gyroscope sensors. The major advantage of the proposed inertial navigation system consists on the fact that it does not require any complex infrastructure to be able to operate. For determining the distance it uses three axis accelerometer sensors,...
