Gravity Disturbance Compensation for Inertial Navigation System
IEEE Transactions on Instrumentation and Measurement, 2019This paper investigates the gravity disturbance compensation for inertial navigation system based on high-resolution global gravity field models. The high-precision gravity is calculated using the European Improved Gravity model of the Earth by New ...

Inertial navigation system for bladder endoscopy
2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011The usage of video endoscopes in cystoscopic interventions of the urinary bladder impedes an intuitive navigation. Although image-based solutions such as panorama images can provide extended views of the surgical field, a real-time 3-D navigation is not supported.

Strapdown Inertial Navigation System Initial Alignment Based on Modified Process Model
IEEE Sensors Journal, 2019In this paper, the nonlinear initial alignment method for Strapdown inertial navigation system is investigated. As an important part of the nonlinear initial alignment method, the dynamic model based on nonlinear error equations is re-derived with the ...

Navigation, 2018
Kinematic constrained navigation is a subset of model-aided navigation systems that is attractive because of its independence from extra hardware equipment. In this study, the error-based Kalman Filter is used for the data fusion process through feedback

Integrated Inertial Reference - Inertial Navigation System
Journal of Aircraft, 1976The value of Inertial Navigation Systems (INS) is reduced for long time-duration flights because uncertainties produce increased position errors with time. A reduction in this position error buildup is obtained from a mechanization concept described in this .paper.

STATISTICAL ESTIMATION IN INERTIAL NAVIGATION SYSTEMS
Guidance and Control Conference, 1966Although navigation systems have generally been developed by solving exactly the dynamic equations of motion, in reality the navigation problem is a statistical one since there are unpredictable errors in the measurements. The advent of very powerful navigation computers makes it possible by using statistical filtering techniques to retrieve more of ...

Inertial Navigation System Modeling
2012Modeling requires representing real world phenomena by mathematical language. To keep the problem tractable the goal is not to produce the most comprehensive descriptive model but to produce the simplest possible model which incorporates the major features of the phenomena of interest.
