Workings of a VOR
 

Can anybody direct me to a suitably technical piece that explains the working of a VOR.
I am not looking for information on how to use them but on how they work.
I have tried a search here and Google but to no avail.
Thanks

Theres an Australian document HERE that gives the basics - but that's the best I could find I'm afraid.

Thanks Chilli Monster,
The bit I am looking for more detail on is how they transmit the variable phase angle rotating field.

from Wikipedia

Then there's Doppler (DVOR) versus Conventional (CVOR) :E

I've recently been working on a web page (still not done!) on this very subject. I've thrown together some notes and posted them here as an Acrobat file for your viewing pleasure. Note that they're dated, disjointed, and cluttered, but they may be a place to start. If you need more let me know and I'll see what I can post. I've got a lot of material but I don't want to upload it if it won't be useful to you.

But, bottom line... near as I can tell, a VOR is a bowling pin with 361 light bulbs inside. Something to do with that and the cosine of an Alford loop array flying out of your azimuth whenever your goniometer spins... :)

No, not your "groiniometer," Jerricho...

Thanks Foxbat01 & av8boy, that was what I was after. :ok:

The moral of this story is don't ask a question for which you are not prepared for the answer !
alford loops, goniometer, suppressed carrier modulation etc
Time to dust off the old notes from university time.:ugh:

Just don't go building one in yer back garden, please. We've all got kinda used to where they all are, and an extra one may cause a bit of confusion.:rolleyes:
