A friend in Texas has confirmed that Loran signals are now up and
receivers are showing position. I am including a note from UrsaNav
regarding this event.
TIME FOR LIFE
UrsaNav Testing Wide-Area Timing Alternative
February 29, 2012. This week, for the first time since August 2010,
advanced Low Frequency (LF) signals, including eLoran are on air in
North America. As a result of a Cooperative Research and Development
Agreement (CRADA) between the United States Coast Guard and UrsaNav,
Inc. live testing of a wide-area precise timing solution has begun.
These initial tests include a comprehensive pallet of signals, including
eLoran, that are being evaluated for their ability to provide a robust,
wide area, wireless precise timing alternative that can operate
cooperatively with GPS, or during periods of GPS unavailability.
Globally, government, industry, and academic experts recognize that
enhanced LF signals, such as eLoran, can provide alternative timing,
either as a standalone service, or as a component of a Position,
Navigation, and Timing (PNT) service. The LF signals operate
independently of Global Navigation Satellite Systems (GNSS), such as
GPS. This recognition has led to a cooperative approach, such as the
CRADA, for testing and examining the benefits of a wide-area timing
solution.
Additional on-air tests are planned at various sites throughout the
United States. Broadcasts will test several different frequencies,
waveforms, and modulation techniques using evolutionary,
state-of-the-art technology. Reception of these broadcasts are planned
at both on-shore and off-shore locations, and will include advanced LF
data delivery techniques. The results of these trials will be presented
at national and international conferences. Any party interested in any
part of the trial, or interested in doing their own measurements are
invited to contact us.
UrsaNav is uniquely positioned to help achieve the CRADA goals. We
provide the worlds most advanced solutions for Low Frequency Alternative
Positioning, Navigation, Timing, and Data, including high performance
eLoran Timing Receivers. We have partnered with Symmetricom, the global
leader in precise time synchronization, and Nautel, the industry-leading
supplier of high-power RF transmitters. This “alliance of expertise”
provides the foundation technology for the best wide area, terrestrial
based alternative to satellite systems such as GPS. GLONASS, and Galileo.

Well darn
Though I can hear them on the longwire with a hp3586. It appears the loran
c preamp may have bit the dust. I checked the austrons with the simulator
and they are doing fine.
Will have to look at the preamp this weekend. Easily fixable generally
speaking.
Can tell at least on the eastcoast that they are running dual rate so 59300
and 99600 I suspect.

A friend in Texas has confirmed that Loran signals are now up and
receivers are showing position. I am including a note from UrsaNav
regarding this event.
What are the odds that any long-term deployment would be
backward-compatible with legacy Loran receivers (not the same as the
initial tests being backward-compatible)? The primary revenue stream
would appear to be from sales of new receivers that use patented
technology (unless the government wants to get back into the business
of subsidizing Loran, which it just vacated -- not very
likely). Cynical, maybe, but it is always a good idea to keep an eye
on the money. I suppose they could make the enhancements transparent
to legacy receivers, so you would buy new receivers if you needed the
enhancements but could also use older receivers if you didn't. But
would they? There does not appear to be an incentive to do so,
absent a government subsidy.
Best regards,
Charles

Hi
The obvious advantage to backwards compatibility would be much greater coverage area. It is a bit tough to envision them getting a reasonable user population with a 100% from scratch approach. Indeed that may be wishful thinking.

What are the odds that any long-term deployment would be backward-compatible with legacy Loran receivers (not the same as the initial tests being backward-compatible)? The primary revenue stream would appear to be from sales of new receivers that use patented technology (unless the government wants to get back into the business of subsidizing Loran, which it just vacated -- not very likely). Cynical, maybe, but it is always a good idea to keep an eye on the money.

Eloran is compatible with the older timing rcvrs. Or at least it was
supposed to be. Now the message suggests that they will try other
modulation modes. I couldn't find anything really further then what was
sent.
I did hook the longwire directly to the austron so far no lock and I am
less then 70 miles from the Nantucket site.
Will keep trying

A document I found via UrsaNav's web site describes the basic premise of
eLORAN, and indicates that it is intended to be backward compatible,
although the timing and navigation performance will not be any better than
before. This seems reasonable. The 'e' part adds a data channel that adds
corrections for propagation and such to improve the accuracy, which
obviously the old receivers can't support.
It appears that the sales pitch is to provide a reliable backup for the
satellite based systems as well as better penetration into urban canyons and
buildings than GPS offers.
The document does provide some predicted performance specs for time and
position.
UrsaNav looks to be selling receivers for this, some of which would be very
small, and some would offer eLORAN plus GNSS capability.

The obvious advantage to backwards compatibility would be much
greater coverage area. It is a bit tough to envision them getting a
reasonable user population with a 100% from scratch approach. Indeed
that may be wishful thinking.
Well, if they get no revenue from legacy users, how does the
increased user base benefit them (and, thus, why would they
care)? The only path I see is, "Get 'em hooked using their old
receivers, and they will need new receivers to replace them as they
decide they can't live without the enhancements or as their old
receivers die." But any number of users might decide that the legacy
capabilities were sufficient. Indeed, other manufacturers might
start producing new legacy receivers without having to pay to license
any of the enhanced technology, and spoil the market for enhanced receivers.
All speculation, of course, but it seems at least facially plausible
to me. Maybe it depends on what is enhanced, and by how much.

The paying customer is the military. They need a backup to GPS. The
hijacking of that drone over Iran proved that point to them.

The publication in the federal register, here
http://www.gpo.gov/fdsys/pkg/FR-2012-01-11/html/2012-307.htm
says they are playing with more than Loran. There are
several MF bands they are playing with as well, in particular
the dGPS bands and 500 kHz.
I noticed a while ago that UrsaNav's UN-151 receiver was advertised
as being "capable of processing multiple signals in the LF and MF bands",
and wondered what the "MF" part was about. That is a bit clearer now.

I did hook the longwire directly to the austron so far no lock and I am
less then 70 miles from the Nantucket site.
Will keep trying

The obvious advantage to backwards compatibility would be much greater
coverage area. It is a bit tough to envision them getting a reasonable user
population with a 100% from scratch approach. Indeed that may be wishful
thinking.

What are the odds that any long-term deployment would be
backward-compatible with legacy Loran receivers (not the same as the
initial tests being backward-compatible)? The primary revenue stream would
appear to be from sales of new receivers that use patented technology
(unless the government wants to get back into the business of subsidizing
Loran, which it just vacated -- not very likely). Cynical, maybe, but it
is always a good idea to keep an eye on the money. I suppose they could
make the enhancements transparent to legacy receivers, so you would buy new
receivers if you needed the enhancements but could also use older receivers
if you didn't. But would they? There does not appear to be an incentive
to do so, absent a government subsidy.

Government subsidy, like letting them use the frequency?
Like paying them as contractors to operate the transmitters.
Best regards,

LORAN C
Seems my fet preamp is working as I discovered this morning. Maybe the fets
filament needed to warm up overnight. May have to dig in a bit. But oddly
after a few minutes neither austron has begun to lock.
I am running a hp 3586 off the same active antenna splitter and hearing the
loran stations at -65 db. Thats a pretty strong signal.
If these do not lock soon perhaps what I am hearing is a different chain.
Regards
Paul.
