The GPS Innovation Alliance has released a statement responding to a July 2 ex parte filing by LightSquared, Inc., in which the company said that an ex parte filing by the alliance last month had “several significant errors or incomplete engineering and technical points,” including what level of noise floor increase constitutes harmful interference and whether significant buffers are needed between GPS and terrestrial operations (TRDaily, July 6).

“While we disagree with LightSquared’s July 2 filing, our focus is on supporting the multi-stakeholder process currently underway among the interested government parties rather than debating LightSquared consultants,” the alliance said. “At the end of the day there are neutral evaluators closely examining these complex issues. We remain engaged in that process, and will address technical issues in further detail at an appropriate time.”
