JAVAD GNSS Announces Partnership with LightSquared

PORTLAND, Oregon — JAVAD GNSS announced that it is partnering with broadband
company LightSquared. In promotional material distributed at 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 networkhas come under fire from users of high-precision GNSS over possible
interference issues.

JAVAD GNSS is promoting its latestreceiver, 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."

LightSquared issued a press release stating the partnership will "develop a
system that will eliminate related interference issues for
high-precision GPS devices." LightSquared said the system can be
adapted to work with high-precision GPS devices including those
already in the agriculture, surveying, construction and defense
industries. 

Javad GNSS has completed the design, madeprototypes, and tested those prototypes, LightSquared said.
Preproduction units will be released for public tests in October,
followed by mass production. High-precision receivers for positioning
applications are expected to go to market by November 2011, and
precision timing devices by March 2012.

To develop thetechnology, Javad GNSS took the existing flagship receivers and
reconfigured the filters and linear amplifiers to make them
completely compatible with LightSquared's bottom 10 MHz of spectrum.
It was a very simple and inexpensive process and was developed in a
matter of days. LightSquared claimed, adding that the additional cost
for this technology is not expected to increase the selling price of
the device to the customer.

"This interference problem isnot a difficult one to solve, once you decide to solve it,'' said
Javad GNSS founder Javad Ashjaee. "We've begun manufacturing
preproduction models and expect to have 25 available within two weeks
— we are not talking in hypotheticals here."

"Thetruth is that high-precision GPS users have a wide range of
interference issues to contend with — from congested frequencies to
intentional jamming. LightSquared made this problem much easier to
solve by moving to spectrum farther away from the core GPS
frequencies. As LightSquared's spectrum neighbor, it's our obligation
to build a wall between our spectrum and LightSquared's. My filter
accomplishes that goal,'' said Ashjaee. "Good fences make good
neighbors.''

"The tests conducted so far by the GPSindustry did not take into account the GPS modernization plan that is
in place," Ashjaee said. "Since we have demonstrated that
LightSquared can certainly coexist with the current GPS satellite
signals, the coexistence will be even stronger when the new GPS
satellites with modern L1C, L2C, and L5 un-encrypted codes are
launched."

JAVAD GNSS presented the chart above and said its receiver will offer these
features on this timeline:

• LightSquared protected: Protected by the JAVAD LNA (low-noise amplifier) system.
  For all precision positioning applications. Multipath mitigate
  features preserved. (November 2011)

• LightSquared compensated: Protected by the JAVAD LNA system and dynamically
  compensated for group delay variations (better than 100 picosecond.)
  For precision timing applications. (March 2012)

• LightSquared integrated: Includes the above two features as well as a
  LightSquared communication module inside. (June 2012).
