GLOBAL POSITIONING SYSTEM (GPS)

Global positioning system is a huge range in space research inventions. Its USA based satellite navigation system which tells the geographical position and navigation of world wide things through satellite. Means its locate the actual position at anytime, anywhere and in any whether and any conditions.

There are Many GPS used by people like car navigation system or a vehicle tracking system. Such systems are used many

specific GPS devices that the people works in present scenario. Mainly GPS system consist three things. These are satellite, earth and the receiver. Satellite are passes the signal from the space then GPS receiver receives those signal on earth and tells the actual position in reference of latitude, longitude and altitude.

A GPS receiver manipulate its position according to the timing of satellite sent the signal from the earth .it continually sent the signal from space and consisting various facts that a time the message was sent by satellite, precise orbital

information and the general system health and rough orbits of all GPS satellites. in the GPS system there

are three segment these segments are:

*Space segment

*Control segment and

*User segment.

This segment makes it easier and more discrete to incorporate the tracing possibilities of everything you could just imagine. it simply to purchase GPS handsets that are readily available into markets. To installing with these GPS receivers, people can correctly locate where they are and easily navigate to where they want to moving, whether walking, driving, flying, or boating.

GPS has also widely used in transportation systems worldwide, providing navigation for aviation, ground, and maritime operations. Disaster relief and emergency services depend upon GPS for location and timing capabilities in their life-saving missions. Everyday activities such as banking, mobile phone operations, and even the control of power grids, are facilitated by the accurate timing provided by GPS. Farmers, surveyors, geologists and countless others perform their work more efficiently, safely, economically, and accurately using the free and open GPS signals.

So you can find anyone of yours with the GPS system and now its time to familiar with a great technology......
