The U.S. GPS Industry Council proposes that: 1. Based on the 2002 precedent established by NTIA/IRAC resulting in the joint industry agreement to protect GPS, NTIA/IRAC to be asked to conduct an analysis including industry and government technical experts to examine the potential for interference using public and private sector operating scenarios within a reasonable timeframe (not to exceed 90 days). In consultation with all affected parties, including technical experts from the US GPS Industry Council member companies and LightSquared, participate in a review of NTIA/IRAC methodology and work program, including contributing technical analysis and ensuring that the operational use scenarios are realistic and well represented. Non—proprietary data on receiver sensitivity to overloading will be made available from several of the US GPS Industry Council member companies. Test conditions under which the data were taken will be stated with the data. The analysis process should include appropriate means for public input and comment. Final action on the LightSquared waiver application will be deferred until the NTIA analysis is completed and transmitted to the Commission.
