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.

A methodological use of inertial navigation systems for strapdown navigation task
2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017This paper presents a study of mathematical description for inertial navigation systems and integration of virtual sensors implementation. Virtual sensors allow to estimate quantities detecting events or changes in its environment, to calculate variables such velocity, position and attitude on rigid or mobile bodies of navigation systems. Recently, the

On an Optical Inertial Navigation System—Part II
IEEE Transactions on Automatic Control, 2008In part I, we developed the optical transfer function of the lens-fiber system for quasi-monochromatic, incoherent excitation, and studied the properties of the kernel function. We also studied the cross-talk between the fibers of the lens-fiber system for a worker bee and an artificial eye, and showed that it is not significant. This allows us in this

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 techniques (EIGEN)-6C4, which is a representative of the high-resolution models.

Inertial navigation system aided by aircraft dynamics
IEEE Transactions on Control Systems Technology, 1999In this work the possibility of using the model of aircraft dynamics as a means for aiding an inertial navigation system is studied. The method is of particular interest for low-grade inertial navigating system (INS). The aiding formulation is introduced, its corresponding mathematical model is derived and used in the design of an appropriate extended ...

Inertial navigation system alignment
2004Alignment is the process whereby the orientation of the axes of an inertial navigation system is determined with respect to the reference axis system. The basic concept of aligning an inertial navigation system is quite simple and straight forward. However, there are many complications that make alignment both time consuming and complex.
