Vehicle Tracking System using GPS and Arduino

Vehicle Tracking systems are very commonly used in fleet management and asset tracking applications. Today these systems can not only track the location of the vehicle but can also report the speed and even control it remotely. In general, tracking of vehicles is a process in which we track the vehicle location in form of Latitude and Longitude (GPS coordinates). GPS Coordinates are the value of a location. This system is very efficient for outdoor application purposes. This kind of Vehicle Tracking System Project is widely in tracking Cabs/Taxis, stolen vehicles, school/college buses, etc.In this project, we are going one step ahead with GPS building a GSM and GPS based vehicle tracking system using Arduino. This Vehicle Tracking System can also be used to  track a vehicle using GPS and GSM and can also be used as Accident Detection Alert System, Soldier Tracking System and many more, by just making few changes in hardware and software.

We have also build many other types of vehicle tracking systems previously, you can check them out if interested

 

Components Required for Arduino based Vehicle Tracking system:

To build a simple vehicle tracking system suing Arduino we will need the following components. 

  • Arduino UNO
  • GSM Module
  • GPS Module
  • 16x2 LCD
  • Power Supply
  • Connecting Wires
  • 10 K POT

 

How can  GSM Module be used to track location:

GPS stands for Global Positioning System and used to detect the Latitude and Longitude of any location on the Earth, with exact UTC time (Universal Time Coordinated). GPS module is the main component in our vehicle tracking system project. This device receives the coordinates from the satellite for each and every second, with time and date.

GPS module SKG13BL

GPS module sends the data related to tracking position in real time, and it sends so many data in NMEA format (see the screenshot below). NMEA format consist several sentences, in which we only need one sentence. This sentence starts from $GPGGA and contains the coordinates, time and other useful information. This GPGGA is referred to Global Positioning System Fix Data. Know more about Reading GPS data and its strings here.

We can extract coordinate from $GPGGA string by counting the commas in the string. Suppose you find $GPGGA string and stores it in an array, then Latitude can be found after two commas and Longitude can be found after four commas. Now these latitude and longitude can be put in other arrays.

Circuit Explanation for Interfacing GSM and GPS with Arduino:

Circuit Connections of this Vehicle Tracking System Project is simple and is shown in the image belwo. Here Tx pin of GPS module is directly connected to digital pin number 10 of Arduino. By using Software Serial Library here, we have allowed serial communication on pin 10 and 11, and made them Rx and Tx respectively and left the Rx pin of GPS Module open. By default Pin 0 and 1 of Arduino are used for serial communication but by using SoftwareSerial library, we can allow serial communication on other digital pins of the Arduino. 12 Volt supply is used to power the GPS Module.

GSM module’s Tx and Rx pins of are directly connected to pin Rx and Tx of Arduino. GSM module is also powered by 12v supply. An optional LCD’s data pins D4, D5, D6 and D7 are connected to pin number 5, 4, 3, and 2 of Arduino. Command pin RS and EN of LCD are connected with pin number 2 and 3 of Arduino and RW pin is directly connected with ground. A Potentiometer is also used for setting contrast or brightness of LCD.

 

GSM and GPS based Vehicle Tracking system using Arduino - Working 

In this project, Arduino is used for controlling whole the process with a GPS Receiver and GSM module. GPS Receiver is used for detecting coordinates of the vehicle, GSM module is used for sending the coordinates to user by SMS. And an optional 16x2 LCD is also used for displaying status messages or coordinates. We have used GPS Module SKG13BL and GSM Module SIM900A.

GPS and GSM based Vehicle Tracking System Block Diagram

When we ready with our hardware after programming, we can install it in our vehicle and power it up. Then we just need to send a SMS, “Track Vehicle”, to the system that is placed in our vehicle. We can also use some prefix (#) or suffix (*) like #Track Vehicle*, to properly identify the starting and ending of the string, like we did in these projects: GSM Based Home Automation and Wireless Notice Board

 

Sent message is received by GSM module which is connected to the system and sends message data to Arduino. Arduino reads it and extract main message from the whole message. And then compare it with predefined message in Arduino. If any match occurs then Arduino reads coordinates by extracting $GPGGA String from GPS module data (GPS working explained above) and send it to user by using GSM module. This message contains the coordinates of vehicle location.

 

GAM and GPS Interfacing with Arduino Code  to Track Vehicle Location 

In programming part first we include libraries and define pins for LCD & software serial communication. Also define some variable with arrays for storing data. Software Serial Library is used to allow serial communication on pin 10 and 11.

#include<LiquidCrystal.h>
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

#include <SoftwareSerial.h>
SoftwareSerial gps(10,11); // RX, TX
char str[70];
String gpsString="";
... ....
.... ....

Here array str[70] is used for storing received message from GSM module and gpsString is used for storing GPS string. char *test=”$GPGGA” is used to compare the right string that we need for coordinates.

After it we have initialized serial communication, LCD, GSM & GPS module in setup function and showed a welcome message on LCD.

void setup() 
{
  lcd.begin(16,2);
  Serial.begin(9600);
  gps.begin(9600);

  lcd.print("Vehicle Tracking");
  lcd.setCursor(0,1);
  ... ....
  .... ....

In loop function we receive message and GPS string.

void loop()
{
  serialEvent();
  if(temp)
  {
    get_gps();
    tracking();
  }
}

Functions void init_sms and void send_sms() are used to initialising and sending message. Use proper 10 digit Cell phone no, in init_sms function.  

Function void get_gps() has been used to extract the coordinates from the received string.

Function void gpsEvent() is used for receiving GPS data into the Arduino.

Function void serialEvent() is used for receiving message from GSM and comparing the received message with predefined message (Track Vehicle).

void serialEvent()
{
  while(Serial.available())
  {
    if(Serial.find("Track Vehicle"))
    {
      temp=1;
      break;
    }
    ... ....
    .... ...

Initialization function ‘gsm_init() is used for initialising and configuring the GSM Module, where firstly, GSM module is checked whether it is connected or not by sending ‘AT’ command to GSM module. If response OK is received, means it is ready. System keeps checking for the module until it becomes ready or until ‘OK’ is received. Then ECHO is turned off by sending the ATE0 command, otherwise GSM module will echo all the commands. Then finally Network availability is checked through the ‘AT+CPIN?’ command, if inserted card is SIM card and PIN is present, it gives the response +CPIN: READY. This is also check repeatedly until the network is found. This can be clearly understood by the Video below.

Check all the above functions in Code Section below.

No GPS Range Means your GPS is not in getting signal from satellite.
you have to place your GPS receiver or GPS antenna outdoor(on the roof, window)..

I wanted to extract only latitude and longitude and display them on lcd so i used this part of the code posted

#include<LiquidCrystal.h>
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

#include <SoftwareSerial.h>
SoftwareSerial gps(10,11); // RX, TX

String gpsString="";
char *test="$GPGGA";
String latitude="No Range ";
String longitude="No Range ";
int temp=0,i;
boolean gps_status=0;

Serial.begin(9600);
gps.begin(9600);
lcd.print("GPS Tracking");
lcd.setCursor(0,1);
lcd.print(" System ");
delay(2000);
//gsm_init();
lcd.clear();
//Serial.println("AT+CNMI=2,2,0,0,0");
lcd.print("GPS Initializing");
lcd.setCursor(0,1);
lcd.print(" No GPS Range ");

get_gps();
delay(2000);

lcd.clear();
lcd.print("GPS Range Found");
lcd.setCursor(0,1);
lcd.print("GPS is Ready");
delay(2000);

lcd.clear();
lcd.print("System Ready");
temp=0;
}

void loop()
{
//serialEvent();
if(temp)
{
get_gps();
//tracking();
}
}

void gpsEvent()
{
gpsString="";
while(1)
{
while (gps.available()>0) //checking serial data from GPS
{
char inChar = (char)gps.read();
gpsString+= inChar; //store data from GPS into gpsString
i++;
if (i < 7)
{

{
i=0;
gpsString="";
}
}
if(inChar=='\r')
{
if(i>65)
{
gps_status=1;
break;
}
else
{
i=0;
}
}
}
if(gps_status)
break;
}
}

void get_gps()
{
gps_status=0;
int x=0;
while(gps_status==0)
{
gpsEvent();
int str_lenth=i;

lcd.print(longitude);
i=0;x=0;
str_lenth=0;
delay(2000);
}

I know but I connected gps module in gateway mode and it worked
it displayed the desired output as discussed in other post
but when i tried to do the same thing displaying it on lcd it is just stuck i mean how is it possible that one time same place is in range and other time it is not.....
Code worked previously but now it is not working...
Please help

Hi. I have tried out this project with sim800l. The lcd works properly and displays that 'network has been found' plus the 'longitude' and 'latitude'.
But when I send the text Track Vehicle, I get no reply.
Can you please help me to solve this???

IF you have Joined together the by putting a GSM Module ontop of Arduino Possible cause may be that the GSM Module has failed to send the message due to lower current since transmission requires much current , try using external power adaptor of 12V and connect it directly to the GSM.........,
In the initial codes try to replace the serialevent() method with this one
void serialEvent()
{
while(Serial.available())
{

if(Serial.find("Track"))
{
lcd.clear();
lcd.println("Message Received");
temp=1;
break;
}
else
temp=0;
}
}
if the "Track Vehicle" is received and read You will see the LCD , and it will prove that its a transmission problem (sendind of the SMS)

PROBLEM SOLVED.........!!!!!!!!!!!!!!!!! For all the People who has the same Problem as mine Just make Sure that your Hardware serial Communication is Configured Properly(Connection between GSM Module and ARDUINO)
i.e The serial monitor repeatedly dispays ATATATATATAT............. Because the GSM Module doesn't Respond meaning that thehardware Serial connection has failed ....
Man thanx 4 the codes .It realy Helped me...........

Initailly even I got the same message on serial monitor i.e ATATATA....
later the code isn't uploading to the ardino board!(avrdude..error relating to port 0)...Could you please tell the changes to be made in the code and the circuit connections.

can you please tell me what does this part of the code do:
while(Serial.available()>0)
{
if(Serial.find("OK"))
at_flag=0;
}

this will read gsm output string and find OK substring or word comming from GSM response. and if matched with OK then set at_flag

SLAAM Saddam Brother; i have sim900 and NEO-6M GY-GPS6MV2 gps it is working well for, just printing longitude and latitude plz guide me for the tracking by sim card like this project THANKFULL 2 u :)

hello guys i wish to know how to do this using proteus and arduino
what are the libraries to included in proteus and arduino and incorporating the gsm mudule and the pgrs/gps mudules

please help i power my sim 800l with arduino uno 5volt on board using a usb port of my laptop,everything went fine but when i send track vehicle, i got no respond.i read sim800l datasheet which says it draw up to 2A of current.my sim800l works with all AT command. but doesnt respond to sms command.please what kind of power should i use to power my sim800l? thanks in advance

please admin,please power a 12volt battery charger with auto cut off of with lcd display...no post of power supply,regulator and battery charger or solar...please see into that

after powering the sim800l with 3.7volt lithium battery,i was able to dial the number in the module and its rings.but when i send message(Track Vehicle) to the module,it only receive the message but nothing was sent back to the number i put in the programming...pls how to i test if a sim800l is working with sms recieving and sending sms using arduino...please urgent feedback is needed.. 

hardware: gps:NEO-6m-0-001 (Gps), and arduino(any type)....make sure your the gps TX is connected to pin10 of the arduino and the RX is left unconnected.... gsm sim800l...i power my sim800l with a full charger power bank battery......Lithium Ion 18600 3.7v Battery... since the sim800l data sheet says it need power of 3.7v-4.2volt and draw current of up to 2A.. after all connection are done.here is the code i used..

during my study of the gsm module i use, i found that my sim800l shutdown when i use serial.find(''Track Vehicle''); so i use the wireless notices board code in the other post and it work fine, so i just have to swap and do some modification to the existing code and it work..command to send is 

#anything u like*    example;
#track* 
#track vehicle*

Sir, this is my final year project, I have got the Arduino UNO R3, GPRS/GSM Shield SIM900 Ver 2.0
I am little confused with my components, My following doubts are,
1. In my GPRS Shield SIM900 there is a in built antenna, what's the purpose of the antenna?
2. is it nesessary to add a GPS module for this project?, if so please recommend a suitable one?
3. But in my Shield i don't have no idea where to plug the GPS module?

Your help would be highly appreciated!

Thank you.

for those that still encounter problem in setting up this circuit to work, double check your connection very well and if its failed to work check the previous page and use the modified code i use for my own circuit

nurul this project can be use for final year project but use just have to make sure you are not having any issue with the connection between the hardware. also make sure you check your hardware datasheet expecially the gsm and the gps for proper power connection 

the issue i had then was that my sim800l doesnt work with ''serial.find''

while(Serial.available()) 
  {
    if(Serial.find("#A."))
    {
      digitalWrite(led, HIGH);
      delay(1000);
      digitalWrite(led, LOW);
      while (Serial.available()) 
      {
      char inChar=Serial.read();
      str[i++]=inChar;
      if(inChar=='*')
      {
        temp=1;
        return;
      } so i tried use other method like the while loop

 

 serialEvent();
    if (temp == 1)
    {
      x = 0, k = 0, temp = 0;
      while (x < l)
      {
        while (str1[x] == '#')
        {
          x++;
          while (str1[x] != '*')
          {
            msg[k++] = str1[x++];
          }
        }
        x++;
      }

 

so check whether your gsm works with the serial.find or the while loop
