WHAT IS GPS

Satellite based navigation system Based on a Constellation about 24 SatellitesDeveloped by UNITED STATES Departments of DEFENCE

(DOD)Only System today able you your exact position On EARTH (Any time ,Any where ,Any weather)

Things which need to be determined:

• Current Locations of GPS Satellites The Distance Between Receiver’s Position and the GPS Satellites

Current Locations of GPS Satellites

GPS satellites are orbiting the earth at an altitude of 11,000 miles.

The orbits, and the locations of the satellites, are known in advance.

GPS receivers store this orbit information for all of the GPS satellites in an ALMANAC*.

All 24 satellites are divided into 6 parts.

There are 4 satellites in each part.A definite orbit is defined for each

part.Each of these 3,000- to 4,000-

pound solar-powered satellites.
