This report documents a study of statistical correlations between Global Positioning System GPS satellite anomalies bit hits and the state of the actual space environment from 1 October 1984 through 31 March 1991. The study compared distributions of space environmental data with GPS anomalies to determine the correlations if any of GPS anomaly occurrences with space environment variables such as global geomagnetic index and protonelectron counts. Using stepwise linear regression and discriminant analysis, correlations were found to be very low. Regression equations were found to predict the probability of satellite anomalies only slightly better than random chance.
