摘　　要：为展示我国首颗脉冲星导航试验卫星XPNAV-1载荷实测数据的性能,采用与国外公布实测数据对比分析的方法,从观测数据计数统计、光子能量响应、计时性能三方面介绍了XPNAV-1卫星发布数据的性能。分析结果表明,我国自主研发的探测器观测结果与国外天文卫星载荷观测结果的一致性较好,未来进一步深入发展将有望应用于脉冲星导航。In order to present the performance of the measured data observed by the detector, this paper introduces the performance in aspects of the photon counts statistics, the energy response and the pulsar timing. The results are compared compared with the ones from the abroad measured data. The results show that the observation results from the detector is same as the astronomical satellites abroad. During further development, the detector is prospected to be applied in pulsar- based navigation.
