Rapsberry Pi: set up GPS - how it works

The Raspberry Pi is a versatile single-board computer with countless possible uses. This practical tip shows you how to set up with this GPS.

Setting up GPS with Raspberry Pi: the hardware

To use GPS with your Raspberry Pi, you need a GPS module:

For example, as a simple and reliable GPS module, you can buy the Ublox Neo 6M GPS module.
Then you need to connect it to your Raspberry Pi. To do this, wire the following connections from the GPS module to those of the Raspberry Pi:
VCC with 3.3V (Pin 1) | RX with TXD / GPIO 14 (Pin 8) | TX with RXD / GPIO 15 (Pin 10) | GND with ground (pin 6)
You can find a PIN assignment on the official website of the Raspberry Pi.

Then you have to install the corresponding software for the GPS module and release the serial interface. To do this, proceed as follows:

To enable the serial interface, open the config file with "sudo nano / etc / inittab".
Delete the following line there: "T0: 23: respawn: / sbin / getty -L ttyAMA0 115200 vt100" and then save the file.
Then edit an additional configuration file with "sudo nano /boot/cmdline.txt".
In this file you have to remove the entries "console = ttyAMA0, 115200 kgdboc = ttyAMA0, 115200".
Then update the installed packages on your Raspberry Pi.
You then have to install additional software for the GPS module. To do this, type "sudo apt-get install minicom gpsd gpsd-clients" in the console.
After the installation you should restart your Raspberry with "sudo reboot now".
Enter "stty -F / dev / ttyAMA0 9600" in the console to inform the module of the appropriate transmission speed.
In order for your position data to be displayed, you must first configure the software with "sudo gpsd / dev / ttyAMA0 -F /var/run/gpsd.sock -n".
You can then start the program. To do this, enter "cgps -s".
