Answer:
B. location
Step-by-step explanation:
Global positioning service or GPS is a kind of tracking mechanism using satellites, whereby the location of an individual or an object can be tracked.
The service utilizes the movement of around 30 satellites which transmit signals travelling at the speed of light, which are intercepted by the user's handset transmissions.
The service observes the rate of transmission of such signals and determines the location of such transmissions based upon that.
GPS determines only the location to where the signals were transmitted and received.
