Abstract：A high\|rate single\|epoch software using GPS double difference, WinTrack, is developed and used to analyze the precision of a dynamic differential positioning solution using high\|rate GPS data with short baselines of 10 Hz and medium baselines of 1 Hz.The single epoch GPS solution accuracy of broadcast ephemeris and three kinds of precise ephemeris (IGU, IGR and IGS) are compared. Experimental results show their accuracy is almost the same under the condition of a medium\|short baseline. A conservative estimation of the accuracy of high\|rate single epoch GPS solution is 1 cm. The accuracy is relative to observational condition, observational time and data quality.
