The technologies NORAD is ‘using’ to track Santa Claus today
As a child, NORAD’s Santa Tracker served as irrefutable evidence that my belief in Santa Claus was completely justified. If the military was tracking Ol’ Saint Nick, then clearly he must be zooming through the sky at near the speed of light on Christmas Eve. The largest and most sophisticated armed forces in the world surely wouldn’t waste resources on following someone who wasn’t real.
Well fast forward a few years later, and I was forced to reconsider my rationale for some things. But NORAD’s Santa Tracker is still one of my favorite Christmas tradition. I even remember a time before there was a fancy website, when you used to have to call in to NORAD’s hotline to find out Santa’s exact coordinates.
And now that I’m an ”adult,” I do find the tracker interesting — but for different reasons. Mostly I’m intrigued by the real-world technologies that NORAD supposedly employs to follow Kris Kringle. These are technologies and resources that are used on a daily basis to do homeland defense, according to the organization. I spoke with Stacey Knott, a spokesperson for NORAD, about what those technologies entail and how they are meant to be used when not pinpointing the location of a magical flying sleigh.
Military satellites
The first essential tool to tracking Santa is satellite surveillance. Specifically, NORAD uses the military’s Space-Based Infrared System, or SBIRS, according to Knott. It’s a constellation of probes that sit in super-high orbits above Earth looking for infrared signatures on the planet below. Infrared is a type of light that can’t be seen but is associated with heat, so SBIRS is good for tracking heat signatures coming off of things like intercontinental ballistic missiles, for instance.
“What we’re looking for here at NORAD is if something is being shot off from somewhere else in the world, and if it’s a threat to North America,” says Knott. “That way, if we need to, we can use our missile defense systems.”
