The Federal Aviation Administration (FAA) and the Research and Innovative Technology

Administration (RITA), both operating Administrations of the DOT, developed this Plan to

provide the framework for definition of the processes and assumptions that will form the basis

for development of the GPS adjacent-band compatibility for GPS civil applications3.

This Plan identifies the processes to (a) derive adjacent-band transmitter power limit criteria for

assumed new applications necessary to ensure continued operation of GPS services, and (b)

determine similar levels for future GPS receivers utilizing modernized GPS and interoperable

Global Navigation Satellite System (GNSS) signals. These processes will be used to develop

and specify adjacent-band transmitter power limits necessary for the protection of GPS and other

space-based GNSS signals for civil applications.
