It is imperative that the GPS national utility remain free of impediments to operation for more than 75 million North American GPS users. This is not simply a "turf war" over spectrum allocation. It is a public safety issue that would threaten the national transportation grid, national ‘financial system, national security, and virtually everyone in the United States. 1 The Lightsafiared proposal will‘result in anunreliable GPS signal receptio n with the following effects: v . Inablllty g)f emerééncy responders to effectively answer calls o Loss o;f pilots‘ primary means of navigation during a final approach e Disruption of training exercises for military service members who routinel y use commercial GPS systems e Loss of the precise timing provided by GPS which is essential for operatio n of the financialy system, power grid network synchronization, and—cellular tefephone system sync‘rirohizgifiqn' énd co'svt_.account‘inkg ; Furthermore, the U.S..

We urge the FCC to conduct technical interference analysis BEFORE granting a waiver to effectively allow a reallocation of spectrum use from .mobile satellite space service to tefrestrial wireless service that is adjacent to the band where GPS operates.
