How to interface a GPS (Global Positioning System) module with Arduino

Have you ever thought how the GPS location mechanism works?

Let's get started with a quick overview of what GPS is and how can you get you coordinates using GPS module by interfacing with arduino.

So GPS is basically a Global Positioning System which gets your current location coordinates using satellites.

The mechanism is called "Trilateration". To understand this let's assume you are standing somewhere on earth with satellite above you in the sky.

All the three satellites will locate you with correct coordinates. Your device automatically choose those satellites above you which are at angle of 120 degree from each other.

Interface GPS with Arduino

Things that you will need from this project :

1) Arduino uno

2) GPS module

3) Arduino IDE

4) Some connecting wires

First you have to make connection of GPS module to arduino

here is the circuit diagram

Make sure that Rx of GPS is connected to Tx of Arduino and similarly Tx of GPS is connected to Rx of Arduino
