Tracking can be defined as the act of monitoring or checking on someone or something. A tracking system is used to observe moving people or objects and provide a timely ordered sequence of location data for further processing. The increasing rate of theft around the world makes tracking useful. Tracking a lost or stolen device on a real-time map interface using the Global Positioning System (GPS) helps reduce/solve this problem. Say no to plagiarism.

The system was originally developed by the US government for military navigation. A GPS navigation device or receiver is a device capable of receiving information from GPS satellites and then calculating the geographic position of the device. Every GPS receiver contains a computer that “triangulates” its own position by obtaining the bearings of at least three satellites. The result is provided in the form of a geographical position - longitude and latitude - with, for most receivers, an accuracy of 10 to 100 meters. Location techniques work in two stages: Signal Measurements and Location Estimation GPS satellites broadcast signals from space, and each GPS receiver uses these signals to calculate its three-dimensional position (latitude, longitude and altitude) as well as the current time. Calculation based on measurements that can be made by the user equipment or telecommunications network. Location tracking appears to be an interaction of various technologies such as mobile telecommunications systems, cellular identification, Global System for Mobile Communications (GSM), general packet radiocommunication. (GPRS) and geographic information systems (GIS). In today's world, smartphone development is witnessing significant advancements in the market with extreme performance parameters. Over the past few years, mobile device development has made significant advancements in memory capacities, advanced processing power, and higher transfer rates, to name just a few performance metrics. Navigation and positioning is one of the most important features available today, the most appreciated and useful entity for the user. Location-based service is actually an intersection of three main technologies which are: “New information and communication technologies” which encompasses “mobile telecommunication system”, wearable devices and information system geographical. One potential area for development in mobile commerce is location-based services (LBS). At the end of September 2002, there were approximately 605.6 million Internet users worldwide. In June 2014, the global number of mobile phone users reached one billion for the first time. Together, the convergence of these technologies promises to bring new services. Worldwide, revenues from mobile commerce, i.e. transactions over wireless telecommunications networks, are expected to exceed $75 billion by 2014. Keep in mind: this is only 'a sample.
