The GPS is a satellite based Radio Navigation system,

that utilizes precise range measurements from the

GPS satellites to determine precise position anywhere

in the world.

It is a computerized information storage

processing and retrieval system that

has hardwareand software especially designed to cope with

geographical referenced spatial data.

Techniques to input geographical information

converting the information to digital form.

Techniques for sorting information in a compact

format on computer disk or digital storage media. Can analyze, make measurements and find

optimum sites or routes and a hosts of other

tasks.

Can predict outcome of various scenarios, candisplay data in the form of maps, images etc.

The Space Segment of

the system consists of

the GPS satellites.

These space vehicles

(SVs) send radio

signals from space.

The nominal GPS Operational Constellation consists of

24 satellites that orbit the earth in 12 hours. There are

often more than 24 operational satellites as new onesare launched to replace older satellites. The satellite

orbits repeat almost the same ground track (as the

earth turns beneath them) once each day.

The Control Segment consists of asystem of tracking stations located

around the world.

The Master Control facility is

located at Schriever Air ForceBase (formerly Falcon AFB) in

Colorado

CONSISTS OF GPS RECEIVER,ANTENNA AND

PROCESSOR

Four satellites are required tocompute the four dimensions of

X, Y, Z (position) and Time. GPS

receivers are used for navigation,

positioning, time dissemination

The Global Positioning System (GPS) is a worldwideradio-navigation system formed from a constellation of

24 satellites and their ground stations. GPS uses these

"man-made stars" as reference points to calculate

positions accurate to a matter of meters. In fact, withadvanced forms of GPS you can make measurements to

better than a centimeter! In a sense it's like giving every

square meter on the planet a unique address. GPS

receivers have been miniaturized to just a few integrated

circuits and so are becoming very economical. And that

makes the technology accessible to virtually everyone.
