Explanation:
GPS Global Positioning Systems was a tool used by who has the need to navigate with the satellite through the microwave radio. Basically, GPS was use for route tracking in individual usage and it can use by different devices like pocket PC, forerunner and etc. But, nowadays a lot of organizations are using GPS technology to increase their business productivity like logistics company use GPS to keep track of the road in order to decrease the delivery time, travel agency or company use GPS to navigate the travel location and so on. The GPS is a rapid growth technology, which provides enhance flexibility and accuracy of positioning tracking for surveying, navigation and GIS data capture. It can divide by front end and back end usage in users’ segment site in a set of business GPS system. Front end consist navigation and back end include GIS data capture and surveying.
GPS was a satellites based system which is space-based navigation system. By communication with the satellites, GPS require 3 parts of segments that are space segment, control segment and user segment. The GPS satellites act as a references point from orbit to ground detect the receivers’ position. By detecting the position, GPS satellites able to receive the data from counting the longitude and latitude of the receivers; then send back the require data to receivers in order to let the pointer move on map files. The map file is a file with extension (.img) which is like image file from our Windows. This map file only available in navigation devices like pocket PC and GPS navigators; GIS data capture was using different method to manipulate the GPS technology and different infrastructure. The famous GPS navigation device manufacturers and services provider are Garmin and Tom Tom. They are using government satellites and only allow accessing the satellites for navigation purpose.
