Id like to understand the basics of how they use GPS / satellite / cellular tower triangulation etc to find location. Ie; a car GPS has no Sim, uses no cell tower coverage but has an accurate location as long as it can see the satellites in the sky. A mobile phone has GPS but relies on cell tower to help find location with some seeming better than others at doing this when there's no cell coverage.

.......from under the great down under.

Cell towers are not used for location from a user viewpoint. Don't believe everything you see on TV shows, although a provider has the ability to do a very rough location by using the currently active cells and relative signal strengths. That function is not available to the user. GPS provides the location by locating from multiple satellites and some fancy maths on the very accurate relative times involved. The more satellites, the better the location accuracy. No SIM is required for GPS. Smart devices may use cell data to assist with things like maps (or maybe they are available off-line like in your GPS navigator, etc) so they can display your location on a pretty map rather than just a set of coordinates which is all the basic GPS unit provides by way of location.
