The official Santa tracking website for the United States is NORAD at noradsanta.org. The website begins reporting information about Santa on December 1st each year, and it tracks his journey on Christmas Eve until he has finished his work early on Christmas Day.
NORAD tracks Santa using satellites that pick up the infrared signature from Rudolph's glowing nose. The NORAD Tracks Santa website reports hourly on Christmas Eve to show where Santa and his sleigh are.
Santa's aviation call sign is Big Red One. There are Santa Cameras placed all over the world so children can see pictures and videos of Santa in different countries at any time.
Canadian NORAD fighter jets are the first to welcome Santa into North America. They fly with him, which gives NORAD more detailed information about where Santa is as he delivers gifts.
