"PORTLAND, Oregon — JAVAD GNSS announced today that it is partnering
with broadband company LightSquared. In promotional material being
distributed the ION-GNSS conference in Portland, Oregon, JAVAD GNSS says
"LightSquared not only can coexist with GPS, it complements it."

"LightSquared's proposal to build a broadband network has come under
fire from users of high-precision GNSS over possible interference issues.

"JAVAD GNSS is promoting its latest receiver, the TRIUMPH-LS
(LightSquared). "TRIUMPH-LS can benefit from LightSquared communication
channels for receiving RTK corrections," JAVAD GNSS said. "LightSquared
communication channels are much faster and less expensive than
conventional channels for RTK correction transmissions."

I have some nice Beach-Front property in Arizona that is up for Sale
also.

And a bridge in New York that can make anybody a millionaire in a
week.

Don't forget they are only claiming compatibility with the lower 10MHz
LTE channel. The testing group never completely dismissed the
possibility of Lightsquared using that channel.

The upper 10MHz channel remains incompatible.

The avionics group suggested many aviation test devices came close as
is. If I recall properly, avionics test receivers exhibited a 30dB
range between the best and worst performing receiver. That would
suggest front end designs exist that are superior with respect to
overload and perhaps a slightly better filter might make the
difference. Evidently, Javad expounded on that concept.

Of course coming close doesn't cut it with respect to protecting the
installed user base. What is to be demonstrated is feasibility for
using the lower portion of the MSS satellite band for future
terrestrial operations.

How much is that bridge?

The real question is if the filter cuts the mustard, then will L^2 pay
for retrofitting filters to all high accuracy receivers in CONUS or
supply all of them with a standardized replacement unit, at the tune
of US$ billions, perhaps tens of billions. And if with the 10MHz guard
band if all other receivers will operate properly without replacement.

To date, L^2 arrogant attitude has placed a large mass of current GPS
users at serious odds with them. And their lack of technical accuracy
in their claims didn't help them at all.

Time will tell.
Also, will they completely abandon the higher 10MHz band ? That needs
to be part of the deal, from the get go.

My take is that if JAVAD is successful in demonstrating that receiver
redesign can work with LightSquared in the lower part of the L-band,
that this might push the industry to do likewise at a HUGE cost to end
users.

JAVAD is a highly respected supplier of precision GNSS receivers. I
doubt they would allow Lightsquared to diminish their reputation.
They have designed equipment that tracks every GNSS signal with
published specifications. Their receivers remove the multipath
component from SVN49. I'll take their claims seriously.

Javad's somewhat sparse claims on Lightsquared co-existence:

http://www.javad.com/jgnss/javad/news/pr20110921.html

The figure near the bottom of the page implies a nearly brick-wall
filter, no real details.

As an aside, confirming CHAS's assertion about tracking SVN 49:

http://www.javad.com/jgnss/javad/news/pr20110421.html

An earlier Javad input on Lightsquared:

http://www.gpsworld.com/gnss-system/...cryption-11887

If nothing else, you have to admire the Selective Availability ad.

For any readers of this forum who aren't familiar with the name Javad
Ashjaee, some background:

http://www.amerisurv.com/PDF/Profess...Interview..pdf

"In September 1981, one week after entering the U.S., he responded to
a Trimble ad for electrical engineers. Within 24 hours of submitting
his resume, he was working at Trimble Navigation, and was the third
engineer (including Trimble himself) who was hired. He vividly
remembers details of his interview with Charlie Trimble. Javad
has tremendous respect for Trimble’s dedication and credits him with
making GPS a commodity product. . . . 'Iowa gave me the knowledge.
Charlie taught me what to do with it,' Javad says."

http://www.engineering.uiowa.edu/events/ashjaee.php

"Ashjaee pioneered high precision GPS technology at Trimble Navigation
from 1981-1986 and introduced the first GPS receiver for high
precision applications that did not require an atomic clock."

I never intended to paint doubt on JAVAD's technical accomplishments.
I read a complete article on Mr. Ashjaee pioneerism and
accomplishments (I believe it was on insidegnss.com), and have the
utmost respect for his work.
Just having a technical solution to the L^2 interference issue (using
new equipment) isn't enough to solve the whole equation, vis-a-vis the
cost of replacing affected receivers, and that's just for starters. I
stand by my opinion that L1 band should never be used for high power
terrestrial signals. This is a horrible precedent. Next some company
will buy cheap spectrum around the L5 band and try the same trick !
Replacing affected high accuracy receivers will cost billions, if L^2
could deploy in such a way that all existing receivers continue to
work and GPS users can upgrade at the same schedule as upgrading away
from semi-codeless (2020 date) then maybe this could be marginally ok.
Otherwise, unless L^2 volunteers to pay for the upgrades at the tune
of several billion US$, it's still unacceptable.
Hopefully just the military schedule to upgrade affected receivers
will drag us into 2020.
One potentially good is this might speed up launching of new GPS
satellites to make L2C and L5 available faster, that might be the only
great thing coming out of this.

Considering that this huge cost will be "sales" for the GNSS
industry... they may really want to sell a lot of new receivers

You can purchase this receiver from JAVAD for $6000 US.

http://www.javad.com/jgnss/sales/events/20110524.html

I'd suppose the LS version is based upon this design. Will
Lightsquared/JAVAD really demonstrate form, fit and function of their
design with respect to other precision survey/scientific devices?

How about avionics NAV systems? One cannot change an internationally
certified design in a few months and call the deed done.

Then they think DoD will send in their classified GPS devices for
modification! They really don't understand the testing and approval
regime for authorizing DoD equipment designs .. a painful process.
It's only for extreme cases of a national security emergency that
allows that design/approval/procurement process to be 'short
circuited' by order from highest authority of DoD. And the
administration is already under scrutiny for that kind of misbehavior.
