Abstract: GPS provides continuous positioning and timing information, anywhere in the world under any weather conditions. Under the US Department of defence, GPS was originally intended for military applications but in the 1980s, they made the system available for civilian use. The scientific uses of GPS is increasing day by day in the field of Military, civil and commercial user.GPS boosts productivity across a wide swath of the economy, to include farming, construction, mining, surveying, package delivery, and logistical supply chain management. Major communications networks, navigation, banking systems, financial markets, and power grids depend heavily on GPS for precise time synchronization. Some wireless services cannot operate without it.
Keywords: GPS, Navigation, Time Synchronization, Scientific uses.
The GPS concept is based on time. The satellites carry very stable atomic clocks that are synchronized to each other and ground clocks. Any drift from true time maintained on the ground is corrected daily. Likewise, the satellite locations are monitored precisely. GPS receivers have clocks as well however, they are not synchronized with true time, and areless stable.GPS satellites continuously transmit their current time and position. A GPS receiver monitors multiple satellites and solves equations to determine the exact position of the receiver and its deviation from true time. At a minimum, four satellites must be in view of the receiver for it to compute four unknown quantities (Three position co-ordinates and clock deviation from satellite time). GPS provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute position, velocity and time.
Objectives The study has been initiated to fulfil the following objectives-
To analyze the basic concept of GPS.
To analyze the various applications of GPS
The paper is descriptive type and mainly based on secondary data, which has been collected from Books, article in journals, innumerable newspapers and different website. Review Of Related Literature Review out published literatures have been examined related to our study- 1.Singal.P. & Chhillar.R.S.(2014) conducted a research study on the various applications of GPS in computer science like wireless video processing & monitoring using mobile, location of automobile in fisheries, marine studies. 2. Verma. P. & Bhatia. J.S. (2013) conducted a research paper and found that the system is about making vehicle more secure by the use of GPS Technology and web application. 3. Hwang.S. & Yu. D. (2012) conducted a research study and found that location awareness and navigation are becoming one of the most important features in mobile phone and smart phone. Personal navigation and location are enlarging the scope of mobile phones. 4. Duncan. M. J., Bandland. H. M. &Mummery. W. K. (2008) conducted a research paper that find out the utility of the global positioning system in the study of health- related physical activity
Need For The Study:
GPS is a modern technology. The importance of GPS in our daily life is undeniable. This is due to the fact that in today‟s dynamic world, the applications of GPS rapidly increases. It has a major goal of making tasks easier to execute as well as solving many humankind‟s problems. It is very importance in the field, like, Health, Crime, Transportation & Communication and the applications of it has been increased.
as GPS continues to advance and direct even more easiness in the field of resources management, there is a need gps newto stress how advantageous it has been to the diverse field of research and development.
