Can you guess what this building is used for?

Andrew Spargo on February 15, 2008

I'm guessing it's either a satellite telecommunications receiver, or a gigantic immitation of a soccer ball ;)

Jessica G. on February 15, 2008

Close-ish on the satellite guess, but not quite. It sure does look like a soccer ball, that's why I titled it that way! :)

Andrew Spargo on February 16, 2008

Hmmm...is it a satellite tracking device then?

Cell phone tower! ;-)

hmmm, thinking better (now that I saw the aiport so close), this could be a radar and... I could guess that we are seeing just the back side. Am I right? ;-) Cheers, Cleber

I would say this is a radar- station. These ball-like constructions serves as a dome (shelter) for the rotating radar-antennas. We have two big "soccer- balls" here on the Koralpe. See on GE the fotos on positions 46°47´39´´N, 14°57´08´´E and 46°47´28´´N, 14°57´25´´E. This balls are definitely radar-domes. GG

Agreed. It's a radar dome. Based on the material properties, probably reinforced fiberglass, the dome is constructed with a certain thickness to match the wavelength of the radar waves. Since the waves pass through the dome without any interference or reflection, this makes the dome completely invisible to the radar antenna, which as Guiseppe says, is happy rotating away inside.

Cheers, Ryan

Hi Ryan, you know what you are speaking of! GG

Jessica G. on February 16, 2008

Guiseppe and Ryan, you're right. This is (as far as we can tell) the Doppler weather radar station for our area.

Whatever it's for - it's a beautiful PIC!!!

I would say this is a nuclear reactor.

Actually It belongs to Edmonton International Airport, as they handle all Air Traffic Controlling for Aircraft between Vancouver and Winnipeg Center. It is a Radar Dome,(Ryan and Gussepie are both right) I worked at the Calgary International airport for almost 6 years and know people who service that equipment.

I believe this is what is called a Terminal Doppler Weather Radar primarily used to detect "Microbursts", which are especially dangerous for landing aircrafts.

Hi Jessica! Looks like I just joined the Doppler Weather Radar club. I had no idea what this thing was! :)

The position of the radar is actually 300m north and 100m west of where the photo is placed. Great shot.

Jessica G. on January 28, 2010

Hi mrbarryb, I placed the marker around where I was when I took the photo, not where the radar itself is. Thanks!

It's Doppler Radar.

To be more precise this a Terminal Surveilance Radar owned and operated by Nav Canada corporation. This one provides for the safe separation and Air Traffic Control associated to Calgary International Airport. It has both a primary and secondary radar function. Not a Doppler weather radar. Uses monopulse techniques for both applications.
