Monitoring of the location and navigation of the destination places can easily be determined by the GPS users. The transportation system in any form has got a giant leap worldwide with advent of this system. Life-saving missions, disaster relief and many other emergency services are getting the worth of this revolutionary system. Cell phone activities, banking system are all being operated with greatest efficiency. These economical services have also become helpful for the farmers, geologists, mariners and pilots, too. Uses of this system are completely safe and have no hazards. The Global Navigation Satellite System (GNSS) is the only functional system of its type which acts completely. Its timing services for the civilian users on worldwide basis are quite perfect. The data that the system provides are available for an unlimited number of people. Time zones, daylight, night, weather conditions do not affect this system to perform poorly.Applications of GPS System include Timing, Space, Environment, Marine, Rail, Aviation, Roads & Highways, Surveying & Mapping, Agriculture, Public Safety & Disaster Relief and Recreation. This system makes use of a constellation with the help of the transmission of specific microwave signals. The GPS receivers possessed by users, the control and monitoring stations located on Earth and satellites orbiting the Earth are the three parts that the GPS System is consisted of. Signals are broadcasted from space by satellites and GPS receivers are used to pick those up and identify. Three dimensional locations along with time are then provided by individual GPS receiver. Three dimensions include latitude, longitude and altitude. In the GPS system, date is written as a week number and a day-of-week number.
