Resumen de Satellite-based location: the technological challenges
Michel Monnerat, Arnaud Masson
Satellite-based location will shape our future, creating new applications. Besides emergency call location, and navigation in cars and on mobile phones, a range of new services will appear in our life: personal assistance and medical care, localized presence services, finding friends, gaming, localized blogs, home zone billing, and so on. To enable the wide commercial success of each service, several key technological challenges need to be met: accuracy; ubiquity of service, including in dense urban areas and inside buildings; delivery of information instantaneously; and low consumption figures. These challenges are targeted by Alcatel in its technological roadmap, which uses its wide expertise to combine satellite positioning with mobile networks, WiFi, WiMAX, and dedicated sensors in handsets. Hybridization of several technologies is the key to meeting these market success factors. As an example, combining satellite positioning with mobile network positioning is the most efficient way to locate persons calling an emergency number (112 in Europe), indoors as well as outdoors.
