Portable Life Protection System for Fishermen Using Global Positioning System

The Global Positioning System (GPS) offers a very easy and a relatively cheap way of finding out ones location on the planet. As the name indicates this project is an application of GPS. It is a very hardship business for fishermen who stand in the middle of the ocean without knowing where they are actually located. This project addresses these problems by providing a preprogramed portable navi...

Use of Portable Global Positioning System ( GPS ) Devices in Exposure Analysis for Time - location Measurement

Exposure analysis is a critical component of determining the health impact of pollutants. Global positioning systems (GPS) could be useful in developing time-location information for use in exposure analysis. This study compares four low cost GPS receivers with data logging capability (Garmin 60, Garmin Forerunner 201, GeoStats GeoLogger and Skytrx minitracker MT4100) in terms of accuracy, prec...

Global Positioning System (A Review)

Accurate measurement of physical activity is a pre-requisite to monitor population physical activity levels and design effective interventions. Global Positioning System (GPS) technology offers potential to improve the measurement of physical activity. This paper 1) reviews the extant literature on the application of GPS to monitor human movement, with a particular emphasis on free-living physi...

The Design and Realization of a Portable Positioning System

In the early 1960s, the Inertial Navigation System (INS) was developed by Litton Industries. INS is a sensor-based, self-contained, dead-reckoning positioning system which uses a computer, motion sensors and rotation sensors to perform continuous positioning. The computation of position, velocity and attitude information of moving objects in INS is different fromGPS-based methods. This informat...
