Is there an on-line directory of TACAN locations? For example, the FAA
lists on
http://www.faa.gov/atpubs/LID/A_B.htm
a TACAN on Bald Mountain Nevada, with designation GBM. However, there
is more than one Bald Mountain in Nevada. I'm looking for lon/lat.

In a previous article, said:

Hmmn, it's not listed there, but thanks for the website. I had that
website but somehow lost the bookmark.

If you want to see navaid data one at a time then

http://www.airnav.com/navaids/

works very well.

Is TACAN still in use? I worked on it briefly in 1956 when I was in the
RAF.

Of course. TACAN was developed by the US Navy for use on its
aircraft carriers, the bearing component of VOR being too large
for shipboard use. Nothing has changed.

Except ICs instead of valves?

Right. Thank you.

It wasn't the size of the electronics, but rather the
large antenna array required of the VOR system. A VOR
antenna must be permanently aligned to the earth,
something not possible with such a large array onboard
a ship. The TACAN system operating on a different
principle than VOR solved the size and alignment problems.

I can't, sorry. I've long forgotten it. Even though I was supposed to
write the Vol 1 for the RAF. After a fortnight they posted me!

The writeup at
http://www.radarpages.co.uk/mob/navaids/tacan/tacan1.htm
has already been mentioned.

Aside from size and earth orientation, TACAN has two advantages
over VOR for shipboard use.

1. TACAN uses a bearing reference direction of due east. For a
shipboard installation, that means a properly corrected compass
reference and a means of correcting the antenna orientation.

2. TACAN incorporates a ranging transponder (DME) in the
transmitter site. The aircraft interrogates the system, and the
site's transponder responds after a fixed 50 microsecond delay.
The site's azimuth and range are typically displayed on a
combined bearing/distance/heading indicator. The combination of
bearing and range display clears up any of the to/from confusion
possible with VOR sites.

That's a fine reference. I saved a bookmark there. It looks as if the
UK TACAN is the same as the USAF TACAN, but I'm still not clear as to
the differences from a VOR. Maybe it's just the frequencies. Or, I
believe all TACANs are supposed to have DME built in.

Here is another description that explains how the VOR ground station signals
are used to determine the radial.

Why? Why not have a heading indicator (or DG) to drive the 'angles' (i.e.
phase) it sends out?

An advantage of VORs over TACANs is the VOR antenna does not physically
more, whereas it does in a TACAN. Electronic "rotation" of the antenna
intuitively makes shipboard use easier, but I might not understand ships
enough!

Operating frequencies dictate the size of the antenna array.
Compare this picture of a TACAN site at
http://en.wikipedia.org/wiki/TACAN with this one of a VOR site at
http://en.wikipedia.org/wiki/VOR.

Other advantages:
Range: TACAN DME has a maximum range of 300 NM miles. VOR
reception range is limited to 25 - 130 NM, depending on the
site's transmitter power.

Bearing accuracy: TACAN can provide bearing resolution of +- 1
degree. Typical VOR bearing accuracy is +- 2 degrees.

A bearing error of 1 degree at 100 miles isn't likely to be
critical on land, but that same error at sea can mean the
difference between finding your carrier and a very long swim
home.

Actually George, the first picture is a VORTAC, a TACAN and VOR
installation. The TACAN is just the round cylinder part and that
is what makes it so easy to mount onboard a ship.

Oops. My mistake on that. I was focusing on the size of the VOR
antenna ring.

We used to carry a portable TACAN (TRN-41) in a backpack for
contingencies in the USAF. Didn't take long to set up and then align so
it could be used.

JPH

I wonder if the TACAN has to move physically. That may be an old
design. Looking at the portable tacan posted later in the threads, it
doesn't look very mechanical.

I don't know much about how either works, other than TACAN transmits its
azimuth signal in the UHF band and DME is an intergal part of the TACAN
station. The DME portion of the TACAN is compatible with civil DME
avionics.

Many of the en route VORs in this country have VOR and TACAN at the same
site. The civil users's airborne DME equipment use the DME portion of
the TACAN station. The official name of one of these sites is VORTAC.

I remember from a recent history or discovery channel program that
air-to-air tacan is still used for aerial refueling operations.

Here's a page about it from Rockwell:

When I was stationed in Thailand, I also heard about A-A mode
being used in a two-ship formation when a major system (attack
radar or INS) failed. The aircraft with working systems would
lead, and the aircraft with the failed system would follow the
leader. As I understand it, buddy bombing was possible, but may
not have been all that accurate.

But, civil aircraft use the TACAN's DME, so they should see the same
range for DME, shouldn't they

Help me with that one. The TACAN ground station is on the ship, right?

If so, angular errors diminish as you approach the station and you
should end up at the ship, whether you started at 150 miles out with a 1
or 2 degree error.

Know this is an old thread.. but..

1 degree sounds like a lot, and would be significant if you were 10 miles away, shot an azimuth and followed that for ten miles.. but with TACAN it's continuous feed of direction and distance so as you get close (picture a funnel) the error becomes less and less, and of course as a plane gets closer to a carrier there are many more control systems that "Capture" the aircraft and provide guidance and landing control.

For an idea of current TACAN and future trends (TACAN is not going away) google TRN 47 Marine Man Portable TACAN, URN 32 Shipboard TACAN.. Fernau TACAN 2010, and Moog MM7000
