SUPPLEMENTARY INFORMATION: 

Background and Purpose

    In December 2012, DOT developed its GPS Adjacent Band Compatibility 
Assessment Plan that 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. The draft test plan outlines the requirements, overall test 
plan, and the associated output data needed to successfully perform 
this component of the GPS Adjacent Band Compatibility assessment.
    DOT has previously held three public workshops to discuss the 
Adjacent Band Compatibility Assessment. Further background, and the 
draft test plan, can be viewed at: http://www.gps.gov/spectrum/ABC/.
