Analysis of Radio Frequency Interference Effects on a Modern Coarse Acquisition Code Global Positioning System Receiver : 9781249578413 : 02 Oct 2012 : The purpose of this thesis was to investigate the performance of a twelve channel Standard Positioning Service (SPS) based Global Positioning System (GPS) receiver using an eight state Kalman filter in a hostile radio frequency (RF) environment and to develop instructional tools for teaching RF interference on GPS receivers. The two types of jamming signals generated included Continuous Wave (CW) and Swept CW. Actual GPS and jamming signals were used in the research. The signals received from GPS satellites exhibit a Doppler shift which vary between approximately ?? six Kilohertz. The Doppler shift frequency can be reasonably predicted for a given time of day, for a given satellite, and for a known receiver location using GPS satellite almanac or ephemeris data. Additionally, the Pseudorandom Noise (PRN) Coarse Acquisition (C/A) code fo
