The database has a large redundant data for Compass Navigation Satellite System (CNSS) always gives different values in different time even the user is stationary. In order to solve the problem, this paper first analyzes the existing algorithm of compressing redundant data based on clustering, and then proposes a comparison algorithm based on time-series. The latter deletes the redundant data so concisely and avoids analyzing the various movement characteristic of users.
