Enhanced Navigation Technology- GPS

Introduction

GPS stands for Global Positioning System, it is used for navigation. Space based satellites are used which gives

the exact information about a particular location and tells correct time to reach the destination.

How It Works

The GPS navigation system is a network of 24 satellites placed in Earth's

orbit by the U.S. Department of Defense. It provides correct location and time information at

any position whether its a day or night, under all weather conditions.

The GPS navigation system devices find use in several applications in the fields of

a)Militaryb)Marine

c)Aviation d)Tracking

e)Surveillance

Uses of GPS Technology

Number of GPS technology applications are there

But the widely known are GPS navigation devices which are used to receive GPS signals on

Earth.

A GPS device gives the information about the Earth's Latitude, Longitute & Altitude.

It displays maps, including streets maps, displayed in human readable format via text or in

a graphical format,

GPS represents turn-by-turn navigation directions to a human in charge of a vehicle or via text or speech, directions fed directly to an automatic vehicle.

It can suggest the shortest route distance between the two locations.

It also represents the area with traffic congestion.

Mobile phones with GPS capability

The GPS technology is getting updated day by day, and its recent advanced advent is named as

A-GPS.

A-GPS stands for Assisted Global Positioning Service.

This service enables a user to navigate through his phone too.

Working Principle Of A-GPS

A-GPS technology was introduced for mobile devices, it takes assistance from GPRS and service provider network. A typical A-GPS mobile phones uses a GPRS or other networks for developing a connection with the server of A-GPS.

GPS & A-GPS Proved Worthy

GPS technology can be used in different modulesSome of them are:-

GPS Navigation DeviceGPS WatchGPS SatelliteGPS Tracking Unit

GPS Watch

A GPS watch is a device with inbuilt GPS receiver that work as a single unit strap onto wrist, GPS watches are generally used for sports and fitness purposes

A GPS satellite is a satellite used by the NAVSTAR Global Positioning System (GPS). The GPS satellite constellation is operated by the 50th Space Wing of the United States Air Force.

GPS Satellite

GPS Tracking Unit

A GPS tracking unit is used to determine the exact location of a vehicle, person, or other asset to which it is attached and to record the position of the asset at regular intervals. The recorded location data can be stored within the tracking unit, or it may be transmitted to a central location data base, or internet-connected computer,

The GPS and A-GPS technology are being advanced day by day, and even enhancing the

navigation experience.Because of its different modules it can be used in

outdoors as well as in indoor applications.
