Bring the World Closer With the Revolutionary GPS Tracking System
Worried about your young ones getting lost in crowds and places like malls, parks etc? Where can your teenage daughter be at midnight away from home? How would you like it if you could track the exact location of the person in question without venturing out in a desperate search? The GPS (Global Positioning System) tracker is one such device which points out precise whereabouts of the person or thing to which it is attached which also records the position at regular intervals.
The tracking is actually done by about 2 dozen satellites which form a navigation system orbiting the earth and controlled by the United States. Signals are transmitted from each satellite that helps determine the latitude and longitude of the GPS receiver device affixed to a person or an asset like a car. The orbital planes around the earth have 4 satellites positioned in them so that the whole world is equipped with the GPS facility.
The recording of the location of the object/person in question done at intermittent intervals can be done within the GPS device or the signals are transmitted to a central database from which it can be retrieved with the help of specialized software.
Based on the mode of data logging and recovery, GPS systems are categorized into 3 types namely.
Data loggers which make use of Flash based memory to store location data and can be recovered or transferred to other devices with the aid of USB connectivity. These are apt for cycling enthusiasts and hikers to chart out their routes.
Data Pushers are high frequency spy devices that send tracking signals of vehicles carrying explosives or other priceless items to a central data base at regular intervals. These are mainly used for security purposes.
For rare tracking purposes like to investigate stolen goods etc. A GPS device known as Data Puller is used. Using this, it is possible to pull data from the receiver as and when needed. It can be incorporated in mobile phones which respond via SMS from the receiver.
