Signal Deformation Analysis of the GLONASS Constellation Using Chip Shape Processing

Mark J. Wireman


The objective of this thesis effort is to characterize the Russian Global Navigation Satellite System (GLONASS) by utilizing advanced chip shape correlation processing techniques to determine C/A code chip shape and other signal characteristics. Fully characterizing GLONASS chip shape will enable signal authentication and provide confidence for potential use of GLONASS in military applications to increase resiliency and frequency diversity in the event of GPS denial. Characterization of GLONASS will also provide additional GNSS resources for improved accuracy and redundancy to our current GPS satellite constellation in the event of GPS spoofing and augmenting the number of satellites available for positioning and timing. Development of software algorithms necessary to characterize the Russian GLONASS C/A code will allow for the potential safe integration of the foreign signals into certain Air Force systems.
