Hello, there.
I have read your job description carefully, You want to receive data (latitude and longitude) that is a location of mobile on a web page every a certain time.
The technology which uses control towers is GSM, and GSM doesn't send the location, GSM sends/receives messages or calls or orders to/from another GSM and it requires money for the mobile chip you will use to send messages.
But this is a way to get a location and display it on a web page by using a GPS module, a microcontroller with a WiFi module.
This is an IoT system what you want to do your job.
Love to work with you and know more if you would like, thanks.
, Mahmoud.
