A special advisory committee will issue a report that validates the aviation community?s concerns about threats to GPS by a proposed broadband communications network.
The committee, part of the not-for-profit organizationRTCA that serves as a federal advisory panel on navigation and air-traffic management policy, issued a summary of its report May 26 stating its conclusion that elements of the cellular network proposal byLightSquared are ?incompatible? with aviation because of potential GPS signal interference. It added that modifications could be made ?to allow the LightSquared system to co-exist with aviation use of GPS.?
?This confirms our message that the concerns expressed by the aviation community and other industries dependent on GPS are warranted, and are now helping to shape the review process,? said Melissa Rudinger, AOPA senior vice president of government affairs.
The report summary called for more study to determine frequency limits versus power for the network?s base stations, taking into consideration the effects of altitude on signal interference and the ?lowest path loss for the low altitude enroute scenario.? The report, which discussed operation at the low and high channel, said the impact of LightSquared?s deployment of upper channel spectrum is expected to be ?complete loss of GPS receiver function.?
