An Anti-SA Filter for Non-differential GPS Users

Hsing-Tung Chou

Abstract:	Selective availability induces large position errors for GPS users. In this paper, SA is modeled and the model parameters are identified by on-line system identification. Combining the results of identification with a Kalman Filter, an adaptive filtering algorithm is implcmented. The effectiveness of this filter to alleviate the SA effects upon non- differential GPS users is justified by static test data.
