Says Study Offers Conclusive Proof Of LightSquared's
Incompatibility With Existing GPS Units
The Coalition to Save Our GPS says a government study released
Wednesday shows conclusively that the 4G wireless broadband
Internet connectivity proposed by LightSquared should not be
allowed on frequencies adjacent to the existing GPS
bandwidth.
Dale Leibach, a spokesman for The Coalition to Save Our GPS,
said in a statement that the results "confirm yet again the depth
and breadth of the serious GPS interference problems raised by
LightSquared’s proposed plans, even after many rounds
of changes to these plans by LightSquared which supposedly
‘solved’ the interference problem."
LightSquared has been saying since June that there were no
interference problems with the GPS devices consumers use every day
in their cars and boats, and that are used every day to make air
travel safer. "The results reported yesterday, which come from
additional testing ordered by the FCC and NTIA, show that in fact
there are substantial risks to all of these everyday activities,"
Leibach said. "In short, the GPS interference problem does not just
affect ‘hundreds of thousands of high precision GPS
receivers,’ but millions of devices in everyday use.
Leibach said that the coalition members are still in the process
of reviewing the detailed interference test results as they become
available. "Unfortunately, based on LightSquared’s public
statements, it is clear that LightSquared simply refuses to accept
the overwhelming technical evidence on the interference issue and
continues to try to ‘define away’ devastating test
results," he said. "For example, LightSquared’s public
statements reject the clearly established interference metric
selected by the expert Federal agency overseeing the tests, calling
the demonstrated interference effects ‘minor.’ This is
grossly irresponsible – the interference threshold used in
the tests represents a 20 percent reduction in the ability of GPS
receivers to process GPS signals. This is not minor.”
