Abstract: Xray pulsar navigation test satellite is a dedicated test satellite developed by China. This satellite has obtained a great mount of science data during the flight of more than 4 months. In this paper, the first analysis result of science data that was collected by the focusing Xray detector carried by the satellite in recently 4 months. The observation mode of this detector is introduced, the method of the science data analysis as well as the pulsar parameters correction are provided, the refined pulsar parameters are estimated, the performance of the detector in orbit is tested, and the question whether homemade Xray detector is able to detect the pulsars is answered.

Key words: flight test, data analysis, Xray detector, profile folding
