I've been searching a lot for pictures showing the innards of VORs, but the closest thing I've found are the insides of NDB, which just look like a bunch of copper coils in a shack. I know how they work, but it seems like if the insides were top secret  Wink

Even if they're as boring as an NDB, I'm still curious.  angel

I just googled VOR and this seems to be the best picture I could find... don't know if its correct.

Thanks MEL and ArmitageShanks. But I think I didn't explain myself well enough.

I was looking for pictures of the inside of the electronics shack of VOR stations.



This pic is of a VORTAC. The actuall VOR antenna is the inverted cone, and the top cylinder is the TACAN antenna. And the base of the VOR is always the radio shack. But i've never seen pictures of what's actually inside the shack.

thx  Smile

Pretty sure they get checked out once in a while inside. Gotta find someone who works on those things.

AKA: the FAA.... Even as Airport Operations we didn't have access to them (or Localizer/Glideslopes too).

The inside of lighting vaults (basically where all the circuits for the different zonesof lights are located) of airports are pretty interesting to see though.

Describe it Big grin

Well our vault was adjacent to the VOR, and the exterior is essentially a brick building plastered in High Voltage signs. Inside is basically rows and rows of what resemble computer servers/mainframes. They are labeled based on what circuit of lights they are for (different zones, as well as what the "mandatory" lights are on). It's pretty noisy inside, being a powerhouse and all, and there is a large amount of ventilation to keep everything cool. It might not be the most exciting thing in the world, but for a normal little 30' x 30' brick building, and knowing what importance the place has, it's pretty cool...

Here is an image I found of google, it's not accurate, but it gives you somewhat of an idea of what I'm trying to describe:

TLAR - that looks about right .  Smile I'd imagine the electronics for the VOR to be similar.

Has anyone ever seen the electronics for the ASOS?
Everyone has seen all the instruments outside, but the sensors collect all the data and send it into a server rack located inside one of the airport buildings which houses all the electronics and battery UPS. At my home airport, the server rack was located in the back of the FBO's office. There's a big WARNING sticker on the outside of the rack warning of severe and swift federal penalties for tampering with the electronics inside the server rack.

That pic above also looks like the inside of the computer room at a TRACON, where the computers merge the primary radar data and secondary transponder beacons with the data tags and send it to the radar distribution switchboard to be displayed on the controller's screens.

The picture also looks like the computer room on an AEGIS warship where all the radar data and data tags are combined and sent up to CIC.

This is a cool topic. I've always wondered about the different designs of the VOR, VORTAC, VOR/DME, And TACAN antenaes.
Most TACAN antennae I've seen look like the cylinder in the picture posted by MEL, and the small objects in a circle around the main antennae are related to DME, I'm not sure.

Any pictures of an NDB antennae? I've done some low fly-by's but I can never get a good look at one. They seem to consist of one or two simple poles.

I wish the US had a more dense VOR coverage. VOR spotting is starting to sound more and more interesting the more I look into it.

How about VORspotting.net?  scratchchin  Big grin

My private pilot instructor got an newsletter from the FAA (don't know the date) and told me the VOR's will be phased out with only select remain in service while GPS will be the primary nav with VOR being secondary.
It said something to 2010 or 2020 that will take effect.

Now that makes me wonder how big/powerful is the backup generator for just the airport's system.

An H-VOR (High power VOR) for enroute navigation pumps out about 200W worth of power, while the T-VOR (Terminal VOR), for navigation within the TMA, is at about 25-50W depending on the range (as a general rule of thumb, 1W would be approximately 1NM for smaller distances), so a single VOR wouldn't put much of a strain on the backup generator (as compared to the lights, ILS, ATC thingies and other high-power devices).

How about the lights on the runways and taxi-ways.

The power output of runway lights varies with their type and intensity, but generally, as far as I can recall, the important lights (threshold, end, edge) of a major airport runway are in the 150-200W-per-light range at full intensity.

However, when switching to a generator, the lights would be dimmed to a reduced intensity, based on the wx situation, and all equipment on airside not vital to safe a/c operations would be disconnected.
