INTRODUCTION

Invented by u.s department of defense(DOD) and

ivan getting.

satellite navigation system designed for

navigation.Man made star.

Known as NAVSTAR(Navigation system for timing

and ranging.

Finding its way into car,boats,planes,constructionequipments,farm machinery and even laptop

computers.

HISTORY

1973 : TIMATION of the U.S airforce and 621B of theU.S navy.

1974-1979: system test.

1977: transmitters are installed on the earths

surface called pseudolities.

1978 1985:11 block satellite launched in this

period.

1983: comes in use for civillian.

1986:accident of the space shuttlechallenger

means a drawback for the GPS program.

CONTI

In 1989:the first block II satellite was installed and

activated.

1990-1991:temporal deactivation of the selectiveavailability(SA).

17.07.1995:Full operational capability is announced.

20.03.2004:launching of the 50st GPS satellite.

25.09.2005:launch of the first IIR M GPS satellite.

Why GPS ?

Location - Determine a basic position

Navigation - Getting from one location to

another Tracking-Monitoring the movement of

people and things

Mapping-Creating maps

Timing-Providing precise timing

How Does GPS Work?

METHOD OF OPERATION.

Satellites transmit signals to equipments on the

ground.

GPS receivers passively receive satellite signals,

they do not transmit.

Each GPS satellite transmits data that indicates itslocation and the current time.


7/21

GPS signals move at the speed of light.

By capturing signals from three or moresatellites exact location is determined.

4th satellite is used for time accuracy.

Each GPS satellite has atomic clocks on board.

GPS Guided Missile

Potential target areas are mapped out ahead oftime, identifying potential targets by their location(height above sea level, latitude, and longitude) withrespect to the GPS satellite system. When an attackraid is planned, the GPS guided missile isprogrammed with the targets GPS coordinates andthe topology of the region surrounding the target.When the missile is then launched, it reads itscurrent GPS position and plots a course to the

target. Additional software onboard the missileenable the missile to follow the terrain in itsapproach to the target. This makes it difficult to spotthe missile on radar or to intercept the missile by anyother means.

HEART FAILURE ALERT SYSTEM

USING RFID AND GPS The Heart Failure Alert

System consists of:

[1]RFID Tag (Implanted

into Human body). [2]RFID Reader (Placed

in a Cellular Phone).

[3]Global Positioning

Satellite System andlocating and trackingstation

[4]Mobile Rescue Units.

The FutureDual/Tri systems (using GPS & Galileo, GLONASS, etc)

Hybrid/Augmented systems(also using cell towers, TV signals, RFID, Wi-Fi, etc.)

LBS (Location Based Services) advertising, via cell phone,mobile ads (busses, taxis), service location/lookup, etc.

Additional Satellites

Additional Ground support (augmentation)

Components the size of a credit card (for under $10.00)

Better clocks in receivers (only need 3 satellites)

Dual (or Tri) Frequency GPS receivers

Track L1and

L2 (& L5?) satellite signals for greater accuracyEnhanced GPS Ability to use low-quality satellite data

(typically filtered out by masks) for estimating positionsunder canopy, inside buildings/cars, etc.

Upgraded satellites sending 3 signals (instead of 1) from eachsatellite, using slightly different frequencies (bettereliminate errors)
