GPS Architecture: usage in Mobile Applications Development

In general sense, any device that receives the Global Positioning System signal for locating the device on any part of the earth is defined as a GPS navigation device. The GPS devices are basically used to provide the latitude and longitude information. They are also used for geocoding of the device once the Mobile application developers are aware of the latitude and longitude information. Most of the usage of the GPS devices are in military, aviation and marine fields. Nowadays, they are also getting popular in consumer product applications.

GPS Tracking Unit Architecture:

This diagram depicts the hardware architecture of an advanced GPS tracker.
Basically, the GPS Tracking Unit uses the Global Positioning System (GPS) to determine the precise location of an object – say a vehicle, person or other asset to which it is attached and to record the position of the asset at regular intervals. The latitude and longitude (location), which is got through the GPS geocoding is then stored within the tracking unit, or it may be transmitted to a central location database, or the internet-connected personal computer, or even any other GPS enabled device such as a radio or satellite.
This GPS tracker contains the GPS module to receive the GPS signal and thus calculate the latitude and longitude coordinates. It also contains the large memory to store the coordinates and additionally contains the modem to transmit this information to a central computer via SMS /GPRS in form of IP address.
