Gps based location tracking in cell phone

 

The GPS project was launched in the United States in 1973 to overcome the limitations of previous navigation systems, [3] integrating ideas from several predecessors, including a number of classified engineering design studies from the 1960s. The U.S. Department of Defense developed the system, which originally used 24 satellites. It became fully operational in 1995. Roger L. Easton of the Naval Research Laboratory , Ivan A. Getting of The Aerospace Corporation , and Bradford Parkinson of the Applied Physics Laboratory are credited with inventing it. [4]

Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS and implement the next generation of GPS Block IIIA satellites and Next Generation Operational Control System (OCX). [5] Announcements from Vice President Al Gore and the White House in 1998 initiated these changes. In 2000, the U.S. Congress authorized the modernization effort, GPS III .

In addition to GPS, other systems are in use or under development, mainly because of a potential denial of access and potential monitoring by the US government. The Russian Global Navigation Satellite System ( GLONASS ) was developed contemporaneously with GPS, but suffered from incomplete coverage of the globe until the mid-2000s. [6] GLONASS can be added to GPS devices which makes more satellites available and enables positions to be fixed more quickly and accurately, to within two meters. [7] There are also the European Union Galileo positioning system and China's BeiDou Navigation Satellite System .

Gps based location tracking in cell phone

If you are developing any location based app, you can make your app more smarter by finding user’s location automatically. For this you need to integrate location modules in your application. This tutorial covers how to integrate location module in your apps.

This tutorial uses older APIs to fetch user’s location. Now google introduced new way of getting user’s location using Google Play Services. Read Android Location API using Google Play Services to get the location using play services.

2 . Open AndroidManifest.xml and add ACCESS_FINE_LOCATION (Which includes both ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION). Also if you are getting network-based location then you need to add INTERNET permission too.

Assisted GPS (abbreviated generally as A-GPS and less commonly as aGPS ) is a system that often significantly improves startup performance—i.e., time-to-first-fix (TTFF), of a GPS satellite-based positioning system. A-GPS is extensively used with GPS-capable cellular phones , as its development was accelerated by the U.S. FCC 's 911 requirement to make cell phone location data available to emergency call dispatchers. [1]

An assisted GPS system can address these problems by using external data. Utilizing this system can come at a cost to the user. For billing purposes, network providers often count this as a data access , which can cost money depending on the plan. [3]

As an additional benefit, in mobile station assisted implementations, the amount of processing and software required for a GPS receiver can be reduced by offloading most of the work onto the assistance server.
