“This is not just an academic exercise,” said Leveson. The research
was undertaken, he said, “to have a basis for policy analysis which
can be used for looking at the implications of actions such as
allowing interference, spectrum sharing [or] reallocation, developing
supplementary backup systems and toughening [receivers].”

The effort was requested by the National Executive Committee for PNT
(the ExCom) after the relative benefits of GPS were questioned by
advocates for LightSquared, a firm that sought in late 2010 to rezone
frequencies near those used by GPS for a terrestrial wireless
broadband network. LightSquared asserted during ensuing political
debate that the benefits of their use of the spectrum, which posed
interference risks to GPS receivers, outweighed the potential costs
to GPS users.
