As usual they were offered the first-class technical exhibition that we have come to expect at this meeting. Almost all the major system suppliers and software houses were present, as were several of the main commercial providers of mapping services in North America. Besides which, all the major U.S. government agencies concerned with mapping (USGS, NOAA, NIMA, EPA, NASA) had interesting displays. However a special feature of this year's technical exhibition was the introduction of a number of new airborne digital frame cameras based on the latest generation of larger-format CCD area arrays that have been released by the manufacturers over the last half-year or so. These arrays provide a substantial increase in performance, especially in terms of the ground coverage and resolution that can be achieved within an individual frame image. Besides these important products, the exhibition also saw the launch of a new airborne multiple camera system and a new airborne pushbroom scanner, both designed to acquire oblique digital imagery. Yet another introduction was that of a new model of an airborne laser scanner. On the DPW front, the exhibition saw the introduction of a number of stereo-displays, including an example of an auto-stereoscopic system, as well as numerous enhancements to DPW software.

GNSS update: positive and negative developments / Huibert-Jan Lekkerkerk in Geoinformatics, vol 9 n° 5 (01/07/2006)

Public [article]  inGeoinformatics > vol 9 n° 5 (01/07/2006) . - pp 24 - 25 Titre : GNSS update: positive and negative developments Type de document : Article/Communication Auteurs : Huibert-Jan Lekkerkerk, Auteur Année de publication : 2006 Article en page(s) : pp 24 - 25 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géodésie spatiale [Termes IGN] European Geostationary Navigation Overlay Service [Termes IGN] fréquence [Termes IGN] Galileo [Termes IGN] Global Navigation Satellite System [Termes IGN] Global Positioning System [Termes IGN] GPS en mode différentiel [Termes IGN] système de positionnement par satellites [Termes IGN] Wide Area Augmentation System Résumé : (Auteur) In the past few months a lot has happened regarding the implementation and testing of new GNSS frequencies. Not all results are positive however, especially with GPS there are some items that warrant attention in the long(er) run. Furthermore critics of the Galileo program seem to be proven partially right when looking at the more recent developments of the program. But not all is amiss in the world of navigation. The EGNOS signal is scheduled to become operational soon and WAAS has been put to use on a new aviation level in the United States. Copyright Geoinformatics.
