Connecting Neo 6m GPS with Raspberry pi 4

Global Positioning System(GPS) - an interesting aspect of modern day tracking helps in getting live updates and also monitor routine.

Why GPS and Raspberry pi ?

GPS data is more of a personal stuff, hence using a private network or service will be under threat to privacy.

Raspberry pi - an open source single board computer that does efficient job of a modern pc willbe more realiable to hold data and process it.

Even, hosting a webserver is highly feasible solution.

Let's begin

connect the GPS module to the Raspberry Pi! 

Mine uses a simple serial connection, so it has to be connected to the Raspberry Pi’s TX and RX pins:


Make sure that you attach the module’s RX input to the Raspberry Pi’s TX output and vice versa! Also note, that I connected the GPS module to the power pins of the Raspberry Pi. Make sure to use the correct voltage for your device.
Configuring the Raspberry Pi for GPS

Next, you have to configure the Raspberry Pi’s OS to be able to communicate with the GPS receiver. Note that these steps apply specifically to Raspbian Jessie or newer. They might differ for older versions. 

Start by running raspi-config:

        
sudo raspi-config


You should see the following screen:


Here you have to select “Interfacing Options” and then “Serial”:


Then disable the possibility to access the login-shell via a serial connection and in the next step, choose “Yes” when you get asked whether you want the serial ports to remain enabled:


When you get brought back to the main menu of the raspi-config program, choose “Finish” and then reboot the Raspberry Pi.

Install gpsd and the gpsd-client:
        
sudo apt-get install gpsd gpsd-clients

gpsd is an interfacing daemon for serial GPS receivers which supports different communication standards.

Once the installation is done, verify that you can receive data from the GPS module. To do that, output the data that it sends over the serial port:

cat /dev/serial0

Start a new gpsd instance that redirects the data of the correct serial port to a socket:

        
sudo gpsd /dev/serial0 -F /var/run/gpsd.sock
    
And then you can run either of the following two commands to display the GPS data:
        
sudo gpsmon
sudo cgps -s
