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:​spectrum/​ABC/​.
