Good morning everybody, today, me and my partner riadh majouli we will present The Geolocation.
The Satellite geolocalisation goal is to calculate, through signals from a constellation of satellites, the current position on the ground facing a terminal equipped with a compatible chip. Network satellite of most known positioning is GPS (Global Positionning System),
Outline Introduction <ul><ul><li>Types of geo location system </li></ul></ul>The geocoding IP Geolocation GSM Geolocation WIFI Geolocation RFID Geolocation Geographic Information System GIS presentation Demonstration & Conclusion Satellite Geolocation
Introduction Aviation Why We May Need Geolocation? Maritime Navigation Direction Cartography Geolocation can be presented as being a process which allows us to locate an object or a person on a plan or a map using its geographical coordinates.
Types of geo location system <ul><li>Cell ID </li></ul><ul><li>EOTD (Enhanced Observed Time Difference) </li></ul><ul><li>It is the least expensive technology because there is no materiel to be set up . </li></ul><ul><li>Since the portable is in a zone covered by network , he is connected to one aerial GSM. </li></ul><ul><li>The mobile phone sends a signal to the stations of vicinity. </li></ul><ul><li>The closest returns him the signal . it's the time passed to receive the signal from the sender, </li></ul><ul><li>and that allows to determinate the localisation of the mobile with a calculator </li></ul>They are going to make a crossing of data got from three aerials relay used when the portable moves .
Types of geo location system The localization of a mobile phone? To locate a mobile phone, ootay set this service up to the user of the French mobile phone. You launch the localization The mobile phone of your yours is located via relays GSM You show the position of yours close in real time
Space Segment <ul><li>The Space Segment of the system consists of the GPS satellites. </li></ul><ul><li>These space vehicles (SVs) send radio signals from space. </li></ul>
Control Segment The control segment of the Global Positioning System is a network of ground stations that monitors the shape and velocity of the satellites' orbits.
User Segment <ul><li>It includes all civilian and military users to receive and exploit information from satellites. </li></ul><ul><li>The system can be saturated. </li></ul><ul><li>The maximum number of GPS users is unlimited. </li></ul>
G eographic Information System <ul><li>Geographic Information Systems is a computer technology that combines geographic data and other types of information to generate visual maps and reports. </li></ul>
G eographic Information System Computers Printers Scanners Network Services Better understanding of data relationships & trends Description and represnting Interpretation and explanation From simple data tracking and storage To complex multidimensional analysis
Conclusion <ul><li>Everyday activities such as mobile phone operations, transports monitoring, delivery management, and many others are facilitated by the accurate timing provided by geolocation processes. </li></ul><ul><li>Future application : </li></ul><ul><li>Google Building Maker </li></ul><ul><li>Augmented reality </li></ul>
