B. GENERAL NEWS ON ACTIVITIES THAT IMPACT THE CORS PROGRAM

FROM THE NEWS
U.S. Officials Mull Standards in Wake of LightSquared Controversy
BY: TITUS LEDBETTER III
Space News
10 February 2012
U.S. transportation and telecommunications officials hope to develop technical standards
that would allow companies planning broadband networks using mobile satellite services
frequencies to tailor their systems to avoid disrupting GPS applications.
The proposal comes amid the still-simmering controversy over LightSquared, whose plans for
a mobile broadband network serving North America have been upended by GPS interference
concerns. LightSquared of Reston, Va., has invested some $3 billion in its satellite-terrestrial
network and has a satellite in orbit, but now faces what might be an insurmountable regulatory
roadblock.
U.S. Deputy Transportation Secretary John Porcari told lawmakers during a Feb. 8 hearing
that his agency would work with the Commerce Department's National Telecommunications and
Information Administration (NTIA) to develop GPS spectrum standards in consultation with
stakeholders in industry. The standards would be crafted so as not to affect emerging GPS
applications that are vital for the economy, public safety and national security.
LightSquared's proposed wholesale broadband service would operate in L-band frequencies
adjacent to spectrum set aside for GPS navigation and timing signals, which are used for a
wide variety of military and civilian applications including aviation safety. The interference
issue primarily affects precision GPS units that receive signals in those adjacent bands,
which the U.S. Federal Communications Commission has set aside for mobile satellite services
but which LightSquared would also use to broadcast from terrestrial towers.
"In general terms, the more precise the GPS receiver -- for example the avionics in an
aircraft -- the more that they are likely to have a wideband receiver that in fact needs to
be able to listen beyond the GPS frequency," Porcari told members of the House Transportation
and Infrastructure aviation subcommittee. "Acknowledging that and building a policy around
that would be, we think, a very good use of staff time and, from a policy perspective,
critical to protecting GPS as an asset."
Thomas Hendricks, senior vice president for safety, security and operations for Airlines
for America, an advocacy group based here, said a government policy is needed to help
federal regulatory agencies navigate GPS issues. He also said the Federal Communications
Commission (FCC) should be required to consult with the National Space-based Positioning,
Navigation and Timing Executive Committee (EXCOM) before taking action on an application
for a terrestrial communications network that may impact GPS.
The EXCOM is a decision-making panel with representation from nine U.S. agencies with a
stake in GPS. The EXCOM coordinated testing that determined last summer that the terrestrial
portion of LightSquared's proposed network would cause unacceptable interference with GPS
applications. LightSquared then proposed a modified plan under which its ground stations
would transmit at reduced power levels and only in its assigned frequencies that are furthest
away from the GPS bands. However, testing of the new operating scheme determined that it
too would interfere with critical precision GPS applications, leading the FCC to withhold
approval of the company's operating plan.
LightSquared has long maintained that the interference problem is caused not by its proposed
system but by GPS receivers that rely on signals that spill outside the assigned GPS band
and into frequencies set aside for mobile satellite services. Company officials say GPS
receiver manufacturers have known about LightSquared's planned service for years yet
continued to produce what they characterize as faulty equipment.
Scott Pace, director of the George Washington University's Space Policy Institute and an
expert on GPS matters, said imposing standards that require GPS receivers to listen only in
specifically designated GPS frequencies is not the answer.
"Receiver standards have been mentioned as a possible way of allowing higher-power emissions
in bands adjacent to the GPS spectrum, or at least creating a more predictable regulatory
environment for new entrants," Pace said during the hearing. "I do not believe this will be
a useful approach and would suggest instead focusing on defining GPS spectrum-protection
criteria."
Jeffrey Carlisle, LightSquared's executive vice president for regulatory affairs and public
policy, strongly disagreed, saying the onus should be on receiver manufacturers to design
less-vulnerable equipment. "It ought to be resistant," he said in a telephone interview.
"And if it is a precision receiver that needs to have access to other spectrum, fine;
design it in a responsible way," incorporating filters to protect against interference.
LightSquared was not represented at the hearing despite its repeated requests to testify,
according to Chris Stern, a company spokesman.
"We are dismayed but not surprised to hear today that this hearing was little more than a
one-sided trial of LightSquared in absentia," Stern said via email Feb. 8. "It is outrageous
that a congressional hearing set up to examine factual issues was only focused on one side
of the story -- a side of the story supported by commercial GPS makers who designed faulty
devices that depend on using spectrum licensed to LightSquared."
LightSquared's predecessor company won a license in late 2004 to deploy a nationwide network
of ground-based repeaters to transmit signals in locations beyond the reach of its satellite,
such as in urban canyons. Opposition from the GPS industry reached fever pitch after the
company was granted conditional approval in early 2011 to offer a terrestrial-only version
of its service, pending the results of testing to resolve the GPS interference question.

LightSquared Asks FCC to Set Technical Standards on GPS Gear
BY: TODD SHIELDS
Bloomberg
07 February 2012
Philip Falcone's LightSquared Inc. asked U.S. regulators to develop technical standards for
the global-positioning system receivers at the crux of a debate over the venture's proposed
nationwide wireless service.
GPS devices pick up signals from "other people's licensed spectrum" causing interference
concerns that could be eliminated by setting an industry standard, Jeffrey Carlisle,
executive vice president, said in a news conference today. The company filed a petition
with the Federal Communications Commission, Carlisle said.
LightSquared has sought final FCC clearance for its network since late 2010 against
opposition from GPS makers and users who say the service would disrupt navigation gear in
cars, tractors and planes. The Reston, Virginia-based company says GPS makers should have
planned to accommodate LightSquared's use of airwaves near those occupied by navigation
devices.
LightSquared's filing today proceeds from "false premises," Jim Kirkland, general counsel
of Sunnyvale, California-based Trimble Navigation Ltd., said in an e-mailed statement.
"Its suggestion that GPS manufacturers should have designed receivers to accommodate a
prohibited use is simply self-serving nonsense," Kirkland said.
The FCC said in an order released April 6 that existing users of airwaves share
responsibility for protecting against interference. The agency may consider establishing
standards setting receivers' "ability to reject interference from signals outside their
allocated spectrum," the agency said in the order.
Tammy Sun, a spokeswoman for the FCC, declined to comment today.

LightSquared Asks FCC to Set Tough Standards for GPS Receivers
BY: BRENDAN SASSO
The Hill
07 February 2012
Wireless startup LightSquared asked the Federal Communications Commission (FCC) on Tuesday
to set tough technical standards for the design of GPS devices.
LightSquared has invested billions of dollars to launch a wireless broadband service, but
tests last year showed its planned network could interfere with GPS devices.
The company says the problem is that GPS receivers are poorly designed and are receiving
signals from outside their designated frequency bands.
"If GPS devices had stayed in their own lane, there wouldn't be an issue with LightSquared's
network," Jeff Carlisle, LightSquared's vice president of regulatory affairs, told reporters
on a conference call on Tuesday.
The GPS industry argues the interference is a result of LightSquared operating powerful
cell towers on frequencies that should only be used by satellites. They say GPS receivers
are too sensitive to effectively filter out LightSquared's powerful signal on nearby
frequencies.
The FCC granted LightSquared a conditional waiver to move forward last year, but after
testing confirmed the interference problem, FCC officials clarified the company will only
be granted final approval to launch its network if it fixes the interference problem.
According to FCC regulations, companies are not entitled to protection from signals outside
of their airwave frequencies, or spectrum.
But it is unlikely that the FCC would allow LightSquared to launch a network that interferes
with millions of critical GPS devices, including aircraft navigation systems, even if the
problem is the result of the GPS receivers picking up signals outside of their spectrum
band.
Carlisle accused GPS companies of making "a too big to fail argument" by saying the FCC
should give them special protection because of the importance of their devices.
With Tuesday's filing, LightSquared asked the FCC to enact new rules to require special
design standards for GPS devices. In the filing, the company argued that GPS receivers
could be fixed using filters or other technical modifications.
"This latest filing yet again proceeds from the same false premises and claims that
LightSquared has repeated ad nauseam in its ongoing effort to deny its obligation to avoid
harmful interference to millions of government and private GPS users," Jim Kirkland, general
counsel of GPS-maker Trimble, said in a statement.
"In its January 2011 order, the FCC's International Bureau made clear that LightSquared
would not be permitted to commence operations until it had demonstrated that it would not
interfere with GPS. LightSquared did not challenge this condition at the time, and has to
live up to it. There is overwhelming technical evidence--including the most recent government
test results--that this condition has not been satisfied. LightSquared's continuing efforts
to move the goal posts are too little, too late."
LightSquared's Carlisle argued the rules would free up more spectrum to use for mobile broadband.
He acknowledged that the FCC's rule-making process would likely take too long to help
LightSquared with its immediate need to move forward, but he said the rules are important
for the long-term regulatory environment. He said the rules would give "predictability and
certainty to both sides."
LightSquared has until mid-March to secure regulatory approval or it risks losing a multibillion
dollar contract with Sprint.
Carlisle said the company has enough money to operate for "several quarters."

Budgetary Sleight of Hand Remains a Galileo Hallmark
BY: PETER B. DE SELDING
Space News
03 February 2012
From its earliest designs a decade ago, Europe's Galileo satellite navigation project has
required as much financial legerdemain as engineering prowess, a characteristic that it
retains to this day judging from the contracts signed Feb. 2.
This is a project that faced a near-death experience several years ago when highly optimistic
cost projections gave way to substantial cost overruns and the project ran out of money.
In what even Galileo skeptics now regard as a masterstroke, the European Commission was
able to siphon farm price support monies from its agricultural budget and use them to keep
Galileo afloat despite a wall of European Union regulations designed to prevent such
now-it's-here, now-it's-there cash transfers.
It was at this point that Galileo managers were warned: The project will have 3.4 billion
euros -- about $4.5 billion at current exchange rates -- to use through the end of 2013 and
not a euro more.
Additional funds would come from the commission's fresh seven-year financing, starting
in 2014, whose total budget will not be known until late 2013.
In mid-2011, the commission determined that it had committed funds totaling 3.15 billion
euros to Galileo, leaving 250 million euros at its disposal in the current budget.
It would use this money to purchase as many Galileo satellites and launches as it could,
and to modify Europe's heavy-lift Ariane 5 rocket so that it could join the European
version of Russia's medium-lift Soyuz vehicle in launching the Galileo constellation of
30 operational satellites and a couple of in-orbit spares.
The Ariane 5 upgrade is scheduled to cost 50 million euros. That left 200 million euros to
buy new satellites. The commission said that depending on the bids it received for the
satellites, it could order six or eight spacecraft with the available money.
But on Feb. 2, the commission announced cash commitments totaling 315 million euros.
The breakdown is 255 million euros for eight satellites, 30 million euros for the Ariane 5
upgrade -- the European Space Agency (ESA) agreed to finance the remaining 20 million euros
for this -- and 30 million euros to reserve three Ariane 5 launches.
Full payment of the Ariane 5 contract would await the arrival of the new seven-year budget
in 2014.
But even with ESA's surprise contribution, the commission's commitment is 65 million euros
more than it has at its disposal.
Given the rules that prevent the commission from borrowing against future budgets, the
question is: Where did the extra 65 million euros come from?
"Of course we saw this and yes, there would appear to be a slight problem," said one
European government official. "If they found additional money, I don't know where it came
from."
Didier Faivre, ESA's director of navigation -- ESA is Galileo contracting authority, acting
on behalf of the commission -- referred questions about the overall Galileo budget to the
commission.
Commission spokeswoman Sara Tironi did not respond to Space News inquiries on Feb. 3.
