It is  time, NORAD is once again  tracking  Santa's journey.   The tracking actually started around 2 this morning  and NORAD (North American Aerospace Defense Command) uses several methods of keeping track of Santa.

Radar, that is part of the North Warning System  has  47 installations across Canada and ALasa.  The radar is watched very closely for  any sign of Santa leaving the North Pole.  ONce  it is confirmed he has  left the North Pole,  NORAD starts using satellite technology to keep track of his  journey.

The satellites have infrared sensors which  means they can see  heat.  NORAD says it can  follow Santa through the infrared  signatures because Rudolph's nose gives off a great deal of heat.

A third method,  is  the Santa Cams.  They are turned on about an hour before Santa enters a country then turned off  after an image of Santa is captured.  Those images are immediately downloaded onto the NORAD  website for  everyone around the world to see.

Finally,  the Jet fighters are used.  Canadian NORAD fighter pilots take off out of Newfoundland and welcome Santa to NOrth AMerica.  Then  other Fighter pilots across the country   escort Santa across Canada.

NORAD, and its predecessor the Continental AIr Defense Command (CONAD) have beentracking Santa since  1955.

But, as the little ones   count down  the time till Santa arrives,   the tracking Santa site  has plenty of activities to keep them busy  .  You can click here to access the site.
