Software Advances in Aided Inertial Navigation Systems

Navigation, 1970
The basic ideas underlying use of Kalman Filters for data mixing in aided inertial systems are developed in a tutorial manner, including the form of the computational algorithm employed as well as the notation in which it is described. Commonality of data-mixing software among many different applications is stressed, and factors underlying success or ...

Multirate problems in aided inertial navigation systems

Proceedings of the IEEE 12th Signal Processing and Communications Applications Conference, 2004., 2004
The main principal of navigation systems is the determination of a vehicle's position and velocity relative to some reference coordinate frame. An inertial navigation system (INS) utilizes inertial properties of sensors mounted aboard the vehicle to execute the navigation function. The system accomplishes this task through appropriate processing of the

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.

Inertial Methods in Hybrid Navigation Systems

Journal of Navigation, 1960
Some general features of inertial and hybrid inertial systems are examined in relation to the navigational problem in its two essential aspects:(i) The present situation.(ii) The action required.As the fundamental D.R. system, inertial navigation has the virtue of independence but suffers from time-dependent errors.

Optical flow and inertial navigation system fusion in the UAV navigation

SPIE Proceedings, 2016
In recent years navigation on the basis of computation of the camera path and the distance to obstacles with the aid of field of image motion velocities (i.e. optical flow, OF) became highly demanded particularly in the area of relatively small and even micro unmanned aerial vehicles (UAV).

Numerical algorithm for navigation in Earth's inertial system

47th International Symposium ELMAR, 2005., 2005
fie paper presents a numerical algorithm wedfor the solving of the navigotion problem in a strap- down inertial system set an a vehicle which has a short mission near by the Earth. The algorithm is divided into two distinct sequences: the establishing of the vehicle's attitude and the calculation of its speed andposition. The introduction comprises the

Gravity-model errors in mobile inertial-navigation systems

Journal of Guidance, Control, and Dynamics, 1986
A high-accuracy inertial-navigation system (INS) is to be used to navigate a land-mobile Vehicle travelling at about 30 knots, Over time periods of 2-4 h or less. Important sources of navigation error are the errors in modeling the anomalous gravity forces acting on the vehicle.

CHOICE OF COORDINATE SYSTEMS IN INERTIAL NAVIGATION

Navigation, 1956
In navigation of any sort, the choice of the system of coordinates in which position of the earth is measured depends on the particular nature of the navigation problem. Ordinarily that system is best which leads to the easiest form of instrumentation and computation.

A novel optimal redundant inertial sensor configuration in strapdown Inertial Navigation System

Proceedings of the 2012 IEEE/ION Position, Location and Navigation Symposium, 2012
This paper presents a novel optimal redundant inertial sensors configuration in SINS with overall considerations of reliability, navigation accuracy, size and cost of system. The optimal number of redundant sensors is determined by considering the reliability and cost.

AC 25-4: Inertial Navigation Systems (Ins)

1966
This circular sets forth an acceptable means for complying with rules governing the installation of inertial navigation systems in transport category aircraft. Other criteria which will afford a demonstration of compliance with applicable requirements are also acceptable.
