(b) What is the minimum number of satellites that enables a Global Positioning System (GPS) receiver to determine one’s longitude/latitude position, i.e., to make a 2D position fix.

Expert Answer:

A 2D position fix is locating an objects horizontal co-ordinates. It means finding out the latitude and longitude of the object and not its altitude.
 
This can be done with the help of three satellites.
