How to find the location of the phone?

Question

satellite navigation

Hello. Interested in the process itself, how to find out the location of the phone, its coordinates relative to another phone. Preferably without google maps. Or is this how "suits" work that accurately transfer animations to 3d editors? What kind of sensors are used or how? What are they made from?

Answer 1

the difference between the gps data of both phones should suit you
