Supplies

NEO-6M GPS Module

Arduino UNO

Arduino IDE App

4 connecting wires (pin wires)

Computer

Connect the Arduino Board

Open the Arduino IDE connect the board. Delete the current code (void setup etc..). Replace with code below (copy and paste it in). This is the code used below.

#include <SoftwareSerial.h>

// The serial connection to the GPS module
SoftwareSerial ss(4, 3);

void setup(){
Serial.begin(9600);
ss.begin(9600);
}

void loop(){
while (ss.available() > 0){
// get the byte data from the GPS
byte gpsData = ss.read();
Serial.write(gpsData);
}
}


Pin Wiring

The NEO-6M GPS module has four pins: VCC, RX, TX, and GND. The module communicates with the Arduino via serial communication using the TX and RX pins, so the wiring couldn’t be simpler

Setting Up Serial Monitor

In the Arduino IDE app, in the top left corner you will see a "tools" button. Press it and the drop down will appear, one of the options is a Serial Monitor. Open the Serial Monitor at a baud rate of 9600. It should look like the image above.

Reading the Data

  1. 110617 – represents the time at which the fix location was taken, 11:06:17 UTC
  2. 41XX.XXXXX,N – latitude 41 deg XX.XXXXX’ N
  3. 00831.54761,W – Longitude 008 deg 31.54761′ W
  4. 1 – fix quality (0 = invalid; 1= GPS fix; 2 = DGPS fix; 3 = PPS fix; 4 = Real Time Kinematic; 5 = Float RTK; 6 = estimated (dead reckoning); 7 = Manual input mode; 8 = Simulation mode)
  5. 05 – number of satellites being tracked
  6. 2.68 – Horizontal dilution of position
  7. 129.0, M – Altitude, in meters above the sea level
  8. 50.1, M – Height of geoid (mean sea level) above WGS84 ellipsoid
  9. empty field – time in seconds since last DGPS update
  10. empty field – DGPS station ID number
  11. *42 – the checksum data, always begins with *
  12. $GPGSA – GPS DOP and active satellites
  13. $GPGSV – Detailed GPS satellite information
  14. $GPGLL – Geographic Latitude and Longitude
  15. $GPRMC – Essential GPS pvt (position, velocity, time) data
  16. $GPVTG – Velocity made good

Additional - HM10-Bluetooth

You can also use a Bluetooth module like the HM10-Bluetooth and connect the data using that.
