Mobile positioning is a technology used by telecommunication companies to approximate where a mobile phone, and thereby also its user, temporaily resides. More properly segregated the term applies more to a locating process rather than a positioning process. Such service is offered as an option of the class of location-based services (LBS). The technology is based around the fact that a roaming mobile phone always communicates wirelessly with one of the closest base stations, so if you know which base station the phone communicates with, you kn ....etc

Indoor localization has been an active area of research for several years. Especially as an enabling technology for location based services, indoor location support is of high interest for many business cases as well as for emergency/security scenarios. Location sensing represents a core component of ambient computing architectures, smart-environments and ubiquitous/pervasive computing architectures. The proliferation of wireless technologies, mobile computing devices, and the Internet has fostered a growing interest in location-aware systems ....etc

The Global Positioning System, usually called GPS,
The Global Positioning System, usually called GPS, is the only fully-functional satellite navigation system. A constellation of more than two dozen GPS satellites broadcasts precise timing signals by radio to GPS receivers, allowing them to accurately determine their location (longitude, latitude, and altitude) in any weather, day or night, anywhere on Earth.

United States Department of Defense developed the system, officially named NAVSTAR GPS (Navigation Signal Timing and Ranging GPS), a ....etc

Introduction

Location related products are the next major class of value added services that mobile network operators can offer their customers. Not only will operators be able to offer entirely new services to customers, but they will also be able to offer improvements on current services such as location-based prepaid or information services. The deployment of location based services is being spurred by several factors:


Competition

The need to find new revenue enhancing and differentiating value added services has been increasing a ....etc

Protection Of Transmission Systems By Using The Global Positioning System

Introduction
This is a new technique for the protection of transmission systems by using the global positioning system (GPS) and fault generated transients. In this scheme the relay contains a fault transient detection system together with a communication unit, which is connected to the power line through the high voltage coupling capacitors of the CVT.

Relays are installed at each bus bar in a transmission network. These detect the fault generated high frequency v ....etc

Tracking and Positioning of Mobiles in Telecommunication

Mobile positioning technology has become an important area of research, for emergency as well as for commercial services. Mobile positioning in cellular networks will provide several services such as, locating stolen mobiles, emergency calls, different billing tariffs depending on where the call is originated, and methods to predict the user movement inside a region. The evolution to location-dependent services and applications in wireless sy ....etc

Have u ever been lost and wished there was an easy way to find out which way u needed to go? How about finding yourself out hiking and then not knowing how to get back to your camp or car? Ever been flying and wanted to know the nearest airport?

Our ancestors had to go to pretty extreme measures to keep from getting lost. They erected monumental landmarks, laboriously drafted detailed maps and learned to read the stars in the night sky.

GPS is a satellite based radio navigation system which provides continuous, all weather, worldwide nav ....etc
