[Termes IGN] robotRésumé : (Editeur) Robots helping with the housework may seem like science fiction, but Waseda University researchers are exploring ways that humanoid robots could live in harmony with humans. To enable robots to navigate household living spaces, the researchers are developing a seamless indoor/outdoor positioning solution using GPS technology with pseudolites.

[Termes IGN] modulation du signal
[Termes IGN] positionnement par GPSRésumé : (Auteur) In last month's column, we took a brief look at some of the technologies that might be used for UbiPos - ubiquitous positioning - to supplement conventional GPS in environments where it performs poorly or not at all such as in concrete canyons and inside buildings. One of the technologies mentioned involves using signals of opportunity radio signals whose primary purpose is for communications or broadcasting but which could be used for positioning and navigation. Potential signals of opportunity include the amplitude modulated (AM) broadcast stations in the medium wave band. Invented just over 100 years ago by the Canadian radio pioneer Reginald Fessenden, AM broadcasting covers large parts of the globe. Despite the recent tendency of AM stations to move to the FM band, most large metropolitan areas still boast a dozen or more stations on the "AM dial." The signals from AM stations can be used to determine the position of a mobile receiver with respect to a reference receiver using time difference of arrival (TDOA) measurements and a supplementary link between the two receivers. Measurements on one transmitter establish a hyperbolic line of position for the mobile receiver and the intersection of this line with another from measurements on a second transmitter establishes the receiver's position. Measurements on additional transmitters can improve the position accuracy and estimate unsynchronized receiver clock differences through a multi-lateration approach. It matters not whether the stations are "talk radio" or "country and western," as it is the carrier phase of the signals which provides the TDOA measurements. Of course, the proposed use of AM radio broadcasts for positioning and navigation is not a new idea. Measurements of the angle of arrival of AM broadcasts have long been used for position fixing in marine and other environments. In this month's column, a team of authors from the U.S. Air Force Institute of Technology describe the simulations and real-world experiments they carried out using a software-defined radio receiver to test the feasibility of AM radio TDOA measurements for positioning and navigation.Copyright Questex Media Group Inc Numéro de notice : A2007-148 Affiliation des auteurs : non IGN Thématique : POSITIONNEMENT Nature : Article DOI : sans Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=28511

[Termes IGN] téléphonie mobileRésumé : (Auteur) Mark Weiser is not exactly a household name. He was a chief technology officer at the Xerox Corporation's famous Palo Alto Research Center. This is the same outfit which brought us laser printing, Ethernet communications, the graphical user interface paradigm (including the mouse), and object-oriented programming. Like many of those who make a significant difference in technical fields, Mark Weiser's contributions are well known but his name is not. Dr. Weiser introduced the concept of "ubiquitous computing." He coined this term in 1988 to describe a new generation of the computer era, where the first two generations, that of the mainframe and the personal computer, would be superseded by one in which computers would disappear into the objects that surround us in our daily life both at the office and at home. He further posited that the best computer is a quiet, invisible servant whose "calm technology" informs us but doesn't demand our focus or attention. His idea, often tagged "UbiComp," has borne fruit and we now have smart coffee pots, smart printers, smart copy machines and the like, all connected via a wired or wireless network. Users of some of the smart devices in our UbiComp world, such as mobile telephones, personal digital assistants, cameras, and camcorders, would benefit by knowing their location wherever they might be - whether it's in an open field, on a street surrounded by skyscrapers, or inside an apartment building. As we all know, conventional GPS receivers don't always work where we would like them to. In order for a UbiComp device to know its position anywhere and anytime, we need "ubiquitous positioning" or UbiPos. And like UbiComp, UbiPos should inform us but not demand our focus or attention. In this month's column, we take a look at the available technologies that might be used to supplement conventional GPS positioning and some initial testing that will eventually lead to a UbiPos world, one in which we can locate anyone, anything, anytime, anywhere.

In turn, photogrammetry can come to the aid of a GPS/INS positioning system by bridging gaps in GPS/INS positions, which frequently occur in urban environments.

[Vedettes matières IGN] GénéralisationRésumé : (Editeur) Users have come to expect instant access to up-to-date geographical information, with global coverage-presented at widely varying levels of detail, as digital and paper products; customisable data that can readily combined with other geographic information. These requirements present an immense challenge to those supporting the delivery of such services (National Mapping Agencies (NMA), Government Departments, and private business. Generalisation of Geographic Information : Cartographic Modelling and Applications provides detailed review of state of the art technologies associated with these challenges, including the most recent developments in cartometric analysis techniques able to support high levels of automation among multi scale derivation techniques.
The book illustrates the application of these ideas within existing and emerging technologies. In addition to providing a comprehensive theoretical underpinning, the book demonstrates how theoretical developments have translated into commercial systems deployed within NMAs.
The book explores relevance of open systems in support of collaborative research and open source web based map services.Note de contenu : Preface.
