GPSOperation
A GPS receivercalculatesitspositionbycarefullytiming the signal sendbythe constellationof GPSsatellitehigh
above the earth.Each satellite continuallytransmitsmassagescontainingthe time the messagewassent, aprecise orbit
for the satellite sending the message (theephemeris),andthe general systemhealthandroughorbitof all GPS satellite.
These signal travel atthe speedlightthroughouterspace andslightlyslowerthroughthe atmosphere.The receiveruses
the arrival time of each message tomeasure distance toeachsatellite thereby establishingthatthe GPSreceiver
approximatelyonthe surfacesof spheres centered ateachsatellite.The GPSreceiverusesalso,when appropriate,the
knowledge thatthe GPSreceiverison (if vehiclealtitude is known)ornearthe surface of a sphere centeredatthe earth
center.Thisinformationis thenusedtoestimate the positionof GPSreceiveratthe intersectionof sphere surfaces.The
resultingcoordinatesare convertedtoamore convenientformthe usersuchas latitude &longitude,onlocationona

Howevera4th
conditionisneededtofor2 reasons.One has to do withposition&the otheris to correctthe GPS
receiverclock.Itturnsout that 3 sphere surfacesusuallyintersectin2points.Thus a fourthsphere isneededto
determine whichintersectionisthe GPSreceiverposition.Fornearearthvehicle,thisknowledge thatitisnearis
sufficienttodeterminethe GPSreceiverpositionsinceforthe case there isonlyone intersectionwhichisnearearth.A
fourthsphere surface isalsoneededtocorrectthe GPS receiverclock. More precise informationisneededforthese
task.An estimate of the radiusof the sphere isrequired.Therefore anapproximationof earth altitude orradiusof the
sphere centeratthe satellitemustbe known.

GSMTechnology:-
GSM (Global systemfor mobile communication,originally group special mobile),is standard setdeveloped by the
European Telecommunication Standard Institute (ETSI) to describetechnologies for second generation (2G) digital cellularnetworks.
Developed as a replacement of firstgeneration (1G) analogcellular networks,the GSM standard originally described a digital,circuit
switched network optimized for full duplex voicetelephony. The standard was expanded over time to includefirstcircuitswitched
data transport, then pocket data transportvia EDGE (Enhanced Data Rates for GSM Evolution). The GSM standard is more impound
after the development of tried generation (3G) UMPS slandered developed by 3GPP.
GSM networks will evolvefurther as they begin to incorporatefourth generation (4G) LTE advanced standards.GSMis a
trademark is owned by the GSM association.
BUZZER:-
A 12V buzzer is connected to port RD.6 (29) of the microcontroller through a driver transistor (Q1). The
buzzer required 12Volt at a current of around 100 ma, which cannot provide by the microcontroller. So the
driver transistor is added. The relay is used to addible alarm indication. Normally the buzzer remains off. As
soon as pin of the microcontroller goes high, the buzzer operates.
RELAY INTERFACE:-
A single pole dabble throw (SPDT) relay is connected to port (30) of the microcontroller through a
driver transistor (Q2). The relay requires 12 volts at a current of around 100 ma, which cannot provided by the
microcontroller. So the driver transistor is added. The relay is used to operates vehicle ignition, external siren,
electronic lock, CCTV camera, strobe light or any other electrical device etc. normally the relay remains off. As
soon as pin of the microcontroller goes high, the relay operates. When the relay operates and release. Diode
D1 is the slandered diode on a mechanical relay to prevent back EMF from damaging Q2 when the relay
release. LED L1 indicate relay is operated. LED has a current limiting resister in series. The LED/resister
combination is simply in parallel with the relay.
