The project consists of three parts. The first part is a mobile device with an embedded GPS and wireless Internet connection to transmit its current location. The second part is a web server that will receive the data, parse it, and store it for access over the Internet. The third component is the user interface that will allow others to visually see where the hand-held GPS device is and has been. To view its location, one could use any device that can connect to the Internet such as a desktop computer, laptop, PDA, or cell phone. The data available through a browser includes a scalable map of the surrounding area, latitude, longitude, speed, and altitude of the hand-held device. The system is intended to be a general purpose tracking device; however, the user interface will be tailored to the university shuttle system.

Determining accurate geo-location of a person or object is of great importance in everyday life. This applies to small children who must attend school and have to take the journey alone. It also applies to aged people who are physically unfit for proper self care. Again it applies to the physically disabled like people with impaired vision, mobility disabled and so on. A cost effective and accurate system is in demand for the said purposes. The GPS based asset or person tracking system is one that makes use of the Global Positioning System (GPS) to determine the precise location of an asset/person to which it is attached. Such a system with cost effective design enables owners to view the present and past positions recorded of the target on Google Map through a purposely designed website or android application. The aim of current project is to develop such a system. The system components consist of a GPS sensor, GSP modem and Arduino Mega2560 processor platform. A button is interfaced with Arduino which is used to trigger the alert system. The system is intended to be carried by the user whose geo-location is of interest to the far away guardian. When the button is pressed Arduino sends the current geo-location of the user to the predefined mobile number. The guardian can then use that latitude/longitude data to map the person in panic on the goggle map or some other tool. With slight modification the system can be operated completely from a battery and can be made truly mobile. Right now for the purpose of demonstration it is made to operate from a regulated power supply derived from 230V AC power system. 3.Related Work [1] Design and Prototyping of Visible Light Indoor Positioning System (1) This report describes the design and prototyping of an indoor positioning system (IPS) using visible light. Current IPS are using RF and/or ultrasound technologies. Devices transmit unique identification (ID) codes, which are received by passive detectors in known fixed locations of a building. The basic system requirements are tracking of static and moving
