Abstract:
GPS-based navigation systems have become very popular,mainly because they let people rapidly explore unknown areas. However, GPS works only outdoors, because the required satellite links are blocked or unreliable inside buildings. For indoor location sensing, many types of sensor sexist, including ultrasonic, infrared, magnetic, and radio sensors. But they all require a permanent electronic infrastructure to facilitate measurements, and localizable objects relying on this infrastructure need special sensors or actu ....etc

Indoor Positioning
by Kalid Azad

1 Introduction
1.1 The Problem of Indoor Positioning
Currently, there is no commonly agreed-upon way to determine position indoors. In contrast, GPS (Global Positioning System) works well outdoors and is almost universally used. However, its signals are weak enough to be blocked by the walls of a building, and thus is not available for indoor applications. Various methods exist for indoor positioning, but all must balance flexibility, cost, and accuracy.

Abstract.
Precise positioning in indoor environments faces different challenges than the outdoor ones. While indoor environments are limited in size to rooms and buildings, outdoor positioning capabilities require regional or even global coverage. Secondly, the difficulty of receipting satellite signals indoors has triggered the development of high sensitive and AGNSS receivers “ with many issues remaining unsolved. Thirdly, the accuracy requirements are dissimilar between indoor and outdoor environments “ typic ....etc

ABSTRACT

This seminar Indoor Positioning and Navigation with Camera Phones discuss about low-cost indoor navigation system runs on off-the-shelf camera phones. The system uses built-in cameras to determine user location in real time by detecting unobtrusive fiduciary markers. The required infrastructure is limited to paper markers and static digital maps, and common devices are used, facilitating quick deployment in new environments. marker-based navigation is easier to use than conventional mobile digital maps. the users' location awarenes ....etc

This seminar deals about working of Indoor Positioning Systems (IPS) and the application of Indoor Positioning Systems (IPS) like patients under care or equipment in a hospital. Indoor Positioning Systems (IPS) locates and track objects in buildings. Most system apply wireless concepts or optical tracking, ultrasound, phase-shift system. commonly The located objects shall be tagged with labels, tags, tokens or transponders to enable locating or positioning.Global navigation satellite systems (GPS or GNSS) are not s ....etc

Abstract

There are potential technologies like WLAN fingerprinting, RFID positioning, and indoor positioning with GPS.But it has always been a challenge to get satisfactory results. AGPS is being used since many years in cellular system. By using the assisted GPS technology in mobile network, its possible to get a more accurate fix with better yield and TTF(time to fix). It would be ideal to integrate indoor LBS technologies with AGPS solution.This seminar discuss more on how we can achieve Cellular Indoor Positioning System
