Re: LightSquared Subsidiary LLC Request for Modification of Its Authority for an
Ancillary Terrestrial Component, File No. SAT-MOD-2010lll8-00239
Dear Mr. Chainnan:
We write to express concern regarding a recent order by the International Bureau
granting LightSquared Subsidi8l)' LLC ("LightSquared") a waiver ofthe "integrated service"
rule with regard to its Mobile Satellite Service license in the L-Band. We urge the full
Commission to give appropriate attention to this matter.
Numerous parties have raised significant concerns about interference from the
LightSquared system into the Global Positioning System (GPS) frequencies. These parties
included the GPS industry, aviation, agriculture, construction, cellular telecommunications
companies and government entities such as the National Telecommunications and
Information Administration (NTlA), the Department ofDefense, the Department of
Transportation, and the Department ofHomeland Security. We have substantial concerns
that LightSquared's proposal places an unacceptable risk to public safety through
interference with GPS receivers necessary for aviation, first responders, agriculture,
construction, maritime navigation, E-911, and national defense systems.
GPS is integral to the functioning ofour economy, and is essential for public safety.
To ensure full protection that GPS service is not compromised in any way, we request the full
Commission require LightSquared to demonstrate non-interference ofGPS as a condition
prior to any operation of its proposed service, and we request the Commission rescind
LightSquared's waiver until this demonstration can be made.
We recognize the Commission's unique obligation to the public, and its commitment
to ensure appropriate use ofthe nation's airwaves. We urge the Commission, therefore, to
ensure the unintelTllpted operation ofour nation's critical GPS system.
Sincerely,
ieIL~,~IcU
