Economical Applications of GPS in Road Projects in India

Abstract

The Global Positioning System (GPS) is a satellite based navigation system made up of a network of 24 satellites placed into orbit by U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, they made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24hours a day. Therefore it has become a widely deployed and useful for commerce, scientific uses, tracking and surveillance. GPS's accurate time facilitates everyday activities such as banking, mobile phone operations and even the control power grids by allowing well synchronized hand-off switching. In general GPS applications are realized in following:•In Air – navigation by general aviation and commercial aircraft•At Sea – navigation by recreational boaters, commercial fishermen, and professional mariners•For Surveyors – cost saving by drastically reducing setup time at the survey and providing incredible accuracyAll above applications employ the service of 4- satellites in the orbit at any point of time. In this paper a new method is suggested for which, software is being developed to get the GPS outputs making use of data from a single satellite. The software is known as ‘Geomatic Engineering Application software’. Its use will bring saving of hiring time of 3- satellites, therefore it would cut down the financial implication to a large extent in any project. GPS application in Road projects is discussed herein with this new concept.
