How is object tracking done, coordinates recorded in the database?

Question

satellite navigation

How is object tracking done, that is, what technologies are used to do this and what is needed for this?
I see it this way... there is some kind of chip that transmits the coordinates of an object every N seconds, which are written to the database. Well, some socket server is already working with the database.
It is not clear how the data should get into the database. That is, how and with what to program the chip, where to get it and how to make it transfer data to the database?
I have seen sites that offer truck tracking services that even transmit data from fuel tanks, not to mention the coordinates.
It's just interesting how it's done, in which direction even to google.
Thank you!

Answer 1

There are many implementation options.
A device is installed on the machine that receives coordinates from a GPS receiver and other sensors (including fuel flow meters and so on). The data is buffered on the device. Then they are sent to the server, either by an HTTP request that pulls some script on the server, or simply via SMS, so that the GSM modem on the server receives these SMS, and some server software receives them and decrypts them. This very script puts the data into the database with a simple SQL query. Nothing complicated architecturally, but plenty of places where you can make nonsense, which will turn out to be another shit service of this kind.
