North American Aerospace Defense Command is a joint organization of Canada and the United States that provides aerospace warning, air sovereignty, and defense for the two countries.
This time of the year NORAD's main job is tracking Santa Claus.
NORAD uses four high-tech systems to track Santa – radar, satellites, Santa Cams and fighter jets.
Tracking Santa starts with the NORAD radar system called the North Warning System. This powerful radar system consists of 47 installations strung across the northern border of North America. On December 24th, NORAD monitors the radar systems continuously for indications that Santa Claus has left the North Pole.
