"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."

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.

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.
