GPS World, March 2011

OUT IN FRONT to withstand some interference from high power broadcasting on adjacent frequencies but nobody has tried so far Any hypothetical fixes for GPS beg a more fundamental question Why should Lightsquared a new entrant with no existing business be allowed to shift the burden of mitigating interference created by its operations to millions of consumers government agencies and businesses who have invested in GPS over the last 30 years Keep in mind that other users of the MSS band will also be affected Many commercial and governmental uses of the very band that LightSquared will occupy with its terrestrial transmitters may also be jeopardized We must also remember that the FCC has its own agenda to implement its National Broadband Plan What is truly difficult to comprehend is that broadband and GPS will serve the same Large scale disruption of the GPS service must not be on our hands due to inaction mobile user Action Needed Please act now Write to your representatives in Congress and to your professional and trade associations If you are an expert on radio or spectrum or GPS or whatever else is pertinent make your comments do your research if possible and publish your results with all due speed Petition the FCC to turn the yellow light to red while other paths to achieving LightSquareds and the FCCs goals are investigated Do not forget the Administration the National Telecommunications Information Administration NTIA represents the president co regulator with the FCC of the spectrum where GPS operates In the recent FCC Order NTIA must review the report on results of the FCC mandated interference study language to protect GPS use in the after the interference study is completed Ask the Secretary of Commerce ence and Technology Policy OSTP to inform the NTIA Administrator to urge the FCC chairman to take this same action to protect GPS in Contact the FCC chairman directly and urge this same action Finally help develop user and danger being posed to GPS and make your elected and congressional representatives aware of the impact that interference with GPS would have on your work The large scale disruption of the GPS service mustnt be on our hands
