A Differential GPS Receiver System Using Atmospheric Noise Mitigation Techniques

Thomas A. Schonhoff

Abstract:	As part of an effort for the Department of Transportation, LinCom has investigated radio receiver structures which use the fact that Differential GPS transmission systems may operate on frequencies for which atmospheric impulsive noise is the major natural interference. This paper presents some of the pertinent aspects of these structures; the first part presents a well-established model for the atmospheric noise; the model has been designed to closely match measured noise parameters. The second part of the paper presents the results of an effort to determine the performance of “near-optimal” receiver structures. The paper shows that these structures are (1) relatively easy to implement and (2) provide for SNR improvements of 4 - 6 dB relative to a conventional receiver structure.
