1 Jan 1971TL;DR: In this paper, a mechanization and error analysis of inertial navigation systems is presented, with an emphasis on terrestrial applications on or slightly above the earth's surface, and a unified error analysis technique is developed that is applicable to virtually all system configurations.
Abstract: This volume offers the avionic systems engineer a fundamental exposition of the mechanization and error analysis of inertial navigation systems. While the material is applicable to spacecraft and undersea navigation, emphasis is placed upon terrestrial applications on or slightly above the earth's surface. As a result, practical considerations are geared toward those aircraft navigation systems of particular current interest. Extensive use is made of perturbation techniques to develop linearized system equations, whose solutions closely approximate those obtained by nonlinear differential equations. A unified error analysis technique is developed that is applicable to virtually all system configurations. The technique provides a greatly simplified method for comparing the performance of competing system configurations.

TL;DR: A number of experimental results are found to be consistent with the possible existence of a physiological inertial system of either a pure or hybrid form, and further investigation of the problems of animal navigation from the standpoint of inertial navigation appears merited.

TL;DR: This chapter discusses how an animal using the mental analogue of a topographical map can episodically take a positional fix, i.e. rely on information collected on site.
Abstract: Animals which regularly depart from and return to fixed positions in their environment can resort to two principally different ways of navigation by using egocentric or geocentric systems of reference. In the first case positional information is obtained by dead reckoning (route integration). A route-integration system provides the animal with a continuous representation of its spatial position relative to its starting point (home). Like a rigidly tightened thread of Ariadne a homeward-bound vector always connects the animal with home. In the second case, the animal is expected to use a map-based system of navigation, i.e. to obtain positional information by virtue of the spatial position it occupies in the larger environmental framework. Rather than relying on information continuously collected en route (dead reckoning), an animal using the mental analogue of a topographical map can episodically take a positional fix, i.e. rely on information collected on site. In central-place foragers like social hymen...

31 Mar 2009TL;DR: In this article, an autonomous robot system including a transmitter disposed within a working area and a mobile robot operating within the working area is described. But the transmitter includes an emitter for emitting at least one signal onto a remote surface above the working areas, and the navigation system includes a receiver responsive to the emitted signal as reflected off of the remote surface and a processor connected to the receiver and configured to determine a relative location of the robot based on input from the receiver.
Abstract: An autonomous robot system including a transmitter disposed within a working area and a mobile robot operating within the working area. The transmitter includes an emitter for emitting at least one signal onto a remote surface above the working area. The mobile robot includes a robot body, a drive system configured to maneuver the robot over a surface within the working area, and a navigation system in communication with the drive system. The navigation system includes a receiver responsive to the emitted signal as reflected off of the remote surface and a processor connected to the receiver and configured to determine a relative location of the robot within the working area based on input from the receiver.
