What is the difference between GPS and GIS?

GPS stands for Global Positioning System. GPS uses satellites that orbit Earth to send information to GPS receivers that are on the ground. The information helps people determine their location.      

GIS stands for Geographical Information System. GIS is a software program that helps people use the information that is collected from the GPS satellites.
