Reliable and precise tracking of devices and assets has triggered the deployment of Location Based Services. Today, LBS is available for a wide range of applications from fleet and traffic management, security, personal navigation, advertising, and marketing, asset and people tracking to theft recovery. Many more new applications are in the making every single day. The acquisition and accurate updating of the device position information in a short time period is a key factor to all these applications. To provide an effective solution it is necessary to determine device position in indoor as well as harsh outdoor environments, such as urban canyons and mountains. The severity of the environment requires a more complex system to overcome the challenges hence multiple technologies are used in tandem to determine the location to the best possible accuracy.
This article throws light upon some of the techniques that are used in mobile devices in order to acquire its device position. Once the location is determined the data is usually sent over a cellular network to the application software.
