How to Make a GPS Tracker with Raspberry Pi Step by Step Guide
Are you interested in tracking locations using a Raspberry Pi? This guide will show you how to make a GPS tracker with Raspberry Pi easily. Whether you want to track a vehicle, a pet, or just experiment with GPS technology, this project will walk you through every step. You’ll learn about the hardware, software, and coding needed to get your GPS tracker up and running.
What You Will Need
- Raspberry Pi (any model with GPIO pins, e.g., Raspberry Pi 3 or 4)
- GPS Module (such as the Neo-6M GPS module)
- MicroSD card with Raspberry Pi OS installed
- Power supply for Raspberry Pi
- Jumper wires (female to male)
- Breadboard (optional, for easier wiring)
- Internet connection for software installation
- A monitor, keyboard, and mouse (or SSH setup for headless use)
Step 1: Set Up Your Raspberry Pi
Install Raspberry Pi OS
First, ensure your Raspberry Pi has the latest Raspberry Pi OS installed. You can download the OS image from the official Raspberry Pi website and flash it onto your microSD card using tools like Raspberry Pi Imager or Balena Etcher.

Connect to the Internet
After booting up your Raspberry Pi, connect it to the internet via Wi-Fi or Ethernet. This connection is essential to install necessary software packages.
Update Your System
Open the terminal and run the following commands to update your system:
sudo apt updatesudo apt upgrade -y
Step 2: Connect the GPS Module to Raspberry Pi
Identify the GPS Module Pins
Your GPS module will have pins typically labeled VCC, GND, TX, and RX. VCC is power, GND is ground, TX is transmit, and RX is receive.
Wiring the GPS Module
Use jumper wires to connect your GPS module to the Raspberry Pi GPIO pins:
- GPS VCC to Raspberry Pi 3.3V (Pin 1)
- GPS GND to Raspberry Pi Ground (Pin 6)
- GPS TX to Raspberry Pi RX (GPIO Pin 15, physical Pin 10)
- GPS RX to Raspberry Pi TX (GPIO Pin 14, physical Pin 8)
Note: Some GPS modules operate at 3.3V logic level compatible with Raspberry Pi. Confirm your module voltage to avoid damage.
Enable Serial Port
By default, the Raspberry Pi’s serial port is used for console access. To use it for GPS data, disable the console login on the serial port:
- Run
sudo raspi-config - Select Interfacing Options > Serial
- Choose No when asked to enable the login shell over serial
- Choose Yes to enable the serial port hardware
- Finish and reboot your Raspberry Pi
Step 3: Install Required Software
Install GPSD and GPSD Clients
GPSD is a daemon that handles GPS data on Linux systems. Install it with:
sudo apt install gpsd gpsd-clients python3-gps -y
Configure GPSD
Edit the GPSD default configuration file to set the GPS device:
sudo nano /etc/default/gpsd
Change or add the following lines:
DEVICES="/dev/serial0"GPSD_OPTIONS="-n"USBAUTO="false"GPSD_SOCKET="/var/run/gpsd.sock"
Save and exit (Ctrl+X, Y, Enter). Restart GPSD:
sudo systemctl restart gpsd
Step 4: Test the GPS Module
Check GPS Data Stream
Run the following command to see raw GPS data:
cgps -s
This opens a terminal interface showing satellite info and your current coordinates. If you see data streaming, your GPS module works!
Troubleshooting GPS Signal
- Make sure your GPS antenna has a clear view of the sky.
- Wait a few minutes for the module to lock onto satellites.
- Verify wiring connections.
Step 5: Write Python Code to Read GPS Data
Create Your Python Script
Open a new Python file:
nano gps_tracker.py
Sample Python Code
Use the following code to read GPS data and print latitude and longitude:
import gpssession = gps.gps(mode=gps.WATCH_ENABLE)
try:
print("Waiting for GPS data...")
while True:
report = session.next()
if report['class']
