ITU-R REPORT M.766-2 PDF

Introduction

This Report refers to Question 83/8, DECIDES 4, i.e. "Is the sharing of frequencies with other systems feasible, and if so, what other systems and under what circumstances?". The Question is addressed for the radionavigation-satellite system, global positioning system (GPS), which provides accurate---------timing and position determination via two satellite-to-Earth transmission channels. This Report addresses the feasibility of this system sharing the 1215-1240 MHz and 1559-1610 MHz bands with terrestrial stations.

A more thorough description of the ----- GPS system and the rationale behind the selection of frequencies is presented in Annex I.
