A Comparison of Multichannel, Sequential, and Multiplex GPS Receivers for Air Navigation

Robert A. Maher

Abstract:	As the NAVSTAR Global Positioning System (GPS) begins moving beyond the initial development stage, potential air navigation users are going to have a considerable range of choices for set designs. This paper describes three of the main receiver architecture approaches: multichannel, sequential, and multiplex (MUX). These major options are compared according to functional capabilities, effects of dynamics on navigation accuracy, and relative cost. Oscillator g-loading effects are addressed. The most appropriate choice for a given military or civil air navigation application likely involves a judicious combination of the various basic set architectures. A general familiarity with NAVSTAR/GPS is assumed.
