Your cell phone uses a timing receiver to coordinate the codes with different

base stations so it is easier to hand off the signal to other towers and ensure that your emergency calls get through. equipment has also revolutionized the study of the earth by aiding the measurement of fault lines before, during, and after earthquakes.
