Autonomous Vehicle Navigation and MappingSystem

Abstract: Autonomous vehicle navigation gains increasing importance in various growing application areas. In this paper we described a system it navigates the vehicle autonomously to its destination. This system provides a communication between vehicle and internet using GPRS modem. This system interfaced with OSRM open source map through internet. So we can decide the robot path from internet. In non-urban Domains such as deserts the problem of successful GPS-based navigation appears to be almost solved, navigation in urban domains particularly in the close vicinity of buildings is still a challenging problem. In such situations GPS accuracy significantly drops down due to unavailability of GPS signal. This project also improves the efficiency in navigation. This system not only relay on GPS. To improve the efficiency it uses location information from inertial sensors also. This system uses rotatable laser range finder for obstacle sensing. This is also designed in such a way that It can be monitored from anywhere through internet.

Providing navigation information based on a navigation state

Abstract: A navigation system comprising a positioning system for determining a relative geographic location of an object; a controller for using location information provided by the positioning system in relation to designated destination information to determine a navigation state; and an indicator activated based on the navigation state to provide an instructional message suggesting a course of action to be taken and to provide a signal to automatically control an illumination system in conjunction with the instructional message, the illumination system visually signaling a navigation direction, wherein the illumination system is physically independent from any display unit of the navigation system.

Recent (1973) improvements in the navy navigation satellite system

Abstract: Removal of the pole wander (Chandler wobble) as a source of bias in the Transit Navigation System has improved the precision available to a stationary user (surveyor). The precision associated with the mean of several (say 20) combined passes should be less than 5 meters. The dominant items in the error budget will remain (for a land-based user) uncertainty in the satellite position and instrumentation errors. For an at-sea, non-stationary user; the errors are much larger and (still) dominated by uncertainties in the user's motion; typically 400 meters/knot of navigator's velocity error. The changes discussed here will not alter this situation in any way. We discuss, herein, just how the polar motion is accounted for in the system. No changes are required of any user's hardware or computer programs. The benefits accrue to him (or her) automatically via an improved precision ephemeris in the satellite which now contains the polar motion implicitly. The improvement will be implemented on Dec. 15, 1973. The Transit Coordinate System is reviewed and the recent performance (accuracy) of the system described.

Non-linear navigation in discussion forums

Abstract: Systems, methods, and other embodiments associated with providing non-linear navigation in a discussion forum are described. One method embodiment includes maintaining a location data that identifies a thread or message to which a user has navigated. The method also includes manipulating a navigation control in a graphical user interface based on actions taken by the user and/or other users of the system. The navigation control facilitates a user moving to points not traditionally reachable in a single vertical navigation step in a discussion forum interface.

Systems and methods for navigation of a graphical user environment

Abstract: Systems and methods are provided for navigating a graphical user interface, or GUI. A list may be invoked by a keyboard shortcut within an integrated development environment, or IDE, for software development wherein there are a number of items such as open files and development tools between which a user must navigate. The list appears in a navigation dialog that comprises the items such as open files, tool windows sorted in a most recently used, or MRU, order, and navigation of abstract views into the data. The list may be invoked by the user from the keyboard by pressing the “Ctrl-Tab” keys, for example, and holding down the “Ctrl” key. Once invoked, the user may navigate the list to select an item to open by using the arrow keys for, example, on the keyboard or pressing the “Tab” key again, for example, while holding down the key used to initially invoke the navigation dialog. Once the user selects the desired item, the navigation dialog may be dismissed by releasing the key used to invoke it.
