The method is too complex to describe here in detail, but the system of hardware
and software that implements the method is the Global Positioning System (GPS).
Global Positioning System
The network of satellites operated and maintained by the USA is the Global Positioning System (GPS). There are other systems, comprised of other constellations of satellites, and operated and maintained by other countries.
You mean latitude and longitude?
A grid. One system is called longitude and latitude
grid system
Global Positioning System (GPS) is a system of satellite tracking that uses a network of satellites to determine the latitude and longitude of a person or object on Earth. It provides accurate and real-time information about the location, speed, and altitude of the target. GPS is widely used in various applications, including navigation, transportation, and outdoor activities.
It depends on the specifics of the network. If it involves satellites, no. If there are no satellites, then yes.
It's all down to timing ! Ground stations 'decode' the amount of time it takes for a signal to 'bounce' from the satellite to the Earth. This pinpoints the location of each GPS satellite - and thus the necessary calculations produce the coordinates
A network of imaginary lines is called a grid or a system of coordinates. It is commonly used in mapping, navigation, and plotting locations on a map or graph.
GPS does not use internet, it uses a constellation of US Airforce satellites that transmit coded radio messages. A GPS receiver picking up the radio messages from at least 4 of these satellites can decode them and determine latitude, longitude, altitude, and UTC time with great accuracy.
On maps, lines of latitude divide the Earth into "rings" of mainly 18 parts with each "ring" having 10 degrees latitude. Lines of longitude then cut across the lines of latitude and thus forming grids. There are mainly 36 lines of longitude spaced at 10 degrees longitude apart. In the end, there are 648 grids on a map if split up in this way.
The network of 36 satellites orbiting Earth for the purpose does.
