GPS Evolution

Now a days its very common in using 3g (third generation) cell phones, but so many ppl donno
about whats the advantages of 3g cells over 2g.


Yup, this is not the discussion to find the difference b/w 2g and 3g cells...


Global Positioning System (GPS) is the one of the main feature which u can c in 3g cells..

Global Positioning System or GPS, is a technology that can give your accurate position anywhere on earth, which need a special GPS receiver that can receive signals from satellites.

Those GPS receivers u can get in 3g cells..


Not only in 3g cells, u can buy a new GPS receivers also and have to configure with the satellite.


It was first owned by United states department of defense, But it is available freely to anyone in the world for use. Other countries have developed similar Satellite Navigation Systems of their own.

Oh yeah, It works anywhere on the planet where you can receive signals from the satellite. You will need a pretty clear view of the sky for GPS to work.

Its mainly depend on the power of the receiver. U can get 2 types
* P code - which are used for military purpose, more accuracy
* C/a code - for normal ppl, not much accurate tan p code.

The most popular use of GPS is for navigation. You can buy a Car Navigation System, which can give you directions while you are traveling. Car Navigation systems are still new in India, but there are some systems already available.

U can feel it in Mercedes E class, BMW x4/x5, Audi q7 etc...


GPS devices cum transmitters are also available in small sizes which can be fitted into a shoe or a watch. These are popular to keep a watch on children. These devices would automatically send you a message when your child goes outside a defined perimeter, or you can know where your child is at any time.

This will be helpful to find children.





Hope u ppl get some idea about GPS...
