i am in final year of electronics and comm.my final year project is vehicle tracking system using gsm and gps module.
in which the tracking device is fixed on car and the device continuously(1 hour interval) send google map link on other cell phone.so guys please help me to complete this project1st where should i buy GSM and GPS module,which model is best for this kind of trecking application?
you have to use rs232 cable ,89c52 kit , sim 300, gps module capable of communication with rs232 and an activated sim cardwysiwyg_imageupload:3310:
PRODUCT NAME : GSM MODEM
HARDWARE : SIM 300 MODULE
COMMUNICATION : RS232
COMMANDS : AT
INPUT VOLTAGE : 12VDC / 1AMP
*************************************************************************************************************************
ANTENNA – PULL THE ANTENNA OUT IF THE SIGNAL IS WEAKHOW TO TEST!!!!
1. INSERT THE SIMCARD INTO SIM TRAY BACKSIDE
2. CONNECT THE RS232 CABLE TO THE PC SERIAL PORT – SERIAL PORT PROPERTIES ( RESTORE DEFAULTS – 9600 BAUD RATE)
3. OPEN HYPERTERMINAL FROM WINDOWS START>PROGRAMS>ACCESARIES>COMMUNICATIONS>HYPERTERMINAL
4. SELECT THE COMPORT WITH BAUD RATE 9600
5. TYPE “AT ” ECHO “OK” IF ECHO IS OK COMMUNICATION IS OK !!!!!!!!!+6. CHECK THE LED STATUS ( NETWORK SERCHING , NETWORK CONNECTED, IS SHOWN IN LED STATUS GIVEN BELOW)
****************************************************************************************************************************
Working state of network status indication LED OUTPUTState SIM300 function
Off SIM300 is not running
64ms On/ 0.8SEC Off SIM300 does not find the network
64ms On/ 3 SEC Off SIM300 find the network
64ms On/ 300ms Off GPRS communication
*****************************************************************************************************************************TO CHQ GAIN – AT+CSQ=?
TO CHK NETWORK – AT+COPS=?Examples for send and receive SMS
For sending SMS in text Mode:
AT+CMGF=1 press enter
AT+CMGS=”mobile number” press enter
Once The AT commands is given’ >’ prompt will be displayed on the screen.
Type the message to sent via SMS. After this, press ctrl+Z to send the SMS.
If the SMS sending is successful, “ok” will be displayed along with the message number.For reading SMS in the text mode:
AT+CMGF=1 Press enter
AT+CMGR= no.
Number (no.) is the message index number stored in the sim card. For new SMS, URC will be received
on the screen as +CMTI: SM ‘no’. Use this number in the AT+CMGR number to read the message.
Voice call
Initiating outgoing call:
ATD+ mobile number; press enter
For disconnecting the active call:
ATH press enter
For receiving incoming call:
ATA press enter**************************************************USEFUL AT COMMANDS FOR SETTINGS *****************************************************************
TO CHANGE BAUDRATE – AT+IPR=BAUDRATE(Ex 9600) 0-115200 For maore details refer AT commands Document page 33
TO SAVE THE SETTINGS AT&W
TO RESTORE FACTORY DEFAULTS TYPE AT&F THEN SAVE IT AT&W

I am working on the vehicle tracking system for my semester project!
plz provide me the circuit diagram and code for help!
i am really pooooor in programming
i am in final year student of electronics and communicatin engineering.My final year project is Advance vehicle secuirity system withtheft control and accident notification using gsm , gps module &PIR sensor.In which gps receiver and gsm modem are placed on car and the device continuously(after certain interval) send longitude ,latitude,time,speed on other stored cell phone.And also the ignition of engine is control by cell phone by sending sms and if any accident is happen to vehicle again it send location of accident .And pir is used to detect the motion of person around the car if it detect the motion then sends sms to owner .
So please help me to complete this project by sending the program code and circuit daigram using at89s52 microcontroller as soon as posible
guys…my project is same as of u with some additions…means i hav to lock/unlock door and ignition on/off…….i hav a lil bit idea about pic programing …kindly plzz help me in code i hav a code and and am able to understand some portion of code…code is given bellow

hey plz mail me the circuit and code of the this project my mail idis [email protected]
Dear all i am also working on a device able to track vehicles and send the lattitude and longitude to the user’s mobile phone.I am using a at89s52 Microcontroller , a GPS module and a GSM module.If possible please send me a error free code and circuit diagram as well
My mail id is [email protected]
i hav bought a SIM300 and GSSM3 seriers GPS module i want to interface it with atmega 128 as it has full duplex UART connectionz…can any one help me in circuit and coding of it????
