For in-orbit Beidou satellites; we make use of precise orbit for broadcast ephemeris SIS error analysis. We not only estimate SISURE; but also take correlation analysis and normality test. Through observational data of October 2012 we find that the average SISURE is 1.45 m; the R-T and T-N have low correlation; while among the other components are micro-correlation. We also find that nearly all the SIS error components do not fit the normal distribution; and large errors can be detected by kurtosis abnormal values; while systematic bias can be detected by skewness abnormal values;
