Analysis of DGPS MSK Receivers in a Non-Gaussian Noise Environment

Benjamin Peterson, Keith Gross, Eric Chamberlin, Gregory Czerwonka, William Jones

Abstract:	A summary of ongoing research analyzing the atmospheric noise environment and various structures of minimum shift keying (MSK), receivers for differential GPS (DGPS) signals is presented. The purpose of the study is to assist in the Coast Guard’s planning of the future DGPS broadcast system in the United States. The purpose is not necessarily to develop the optimum receiver but to determine how well typical high quality receivers operate in the atmospheric noise environment. This information is intended for use in the development of minimum performance specifications and in establishing parameters for determining coverage limits. Issues considered include how to define signal to noise ratio with noise probability density functions (pdf’s) that suggest infiite noise variance, and comparative performance of various receiver structures, techniquts for handling impulse noise, and bandwidths.
