  • Abstract:
    The Global Positioning System (GPS) is significant because it is a key element in the development of the ?Free Flight? air traffic management structure of the future which is needed to enable the expected growth of air travel and alleviate the currently overcrowded air routes. It

    is also fast becoming the technology of choice in other public safety positioning and navigation applications (e.g., E-911, maritime, IVHS) and has become imbedded in the national AC power and telecommunications infrastructure. GPS uses, however, a set of rather weak radio signals from satellites in 20,200 kilometer high orbits and, as such, is susceptible to being overpowered by strong terrestrial interference. It operates in one of the ?restricted frequency bands? of Title 47 C.F.R. Part 15 and requires protection from harmful interference by international treaty. The FCC in its May 2000 Notice of Proposed Rule Making (on ET Docket 98-153) proposed to allow intentional ultra-wideband (UWB) transmissions across the GPS and several other restricted frequency bands of key importance to aviation and other public safety applications. The proposed power level had previously been allowed only for unintentional spurious emissions.
