%X The outlier detection methods in satellite gravity gradiometry including threshold method,Grubbs's test,Dixon test,wavelet method and combined method are studied.On the basis of the the origin and properties of satellite gravity gradiometry outliers,the gravity gradiometry dataset with outlier are simulated.The results indicate the combination of Dixon test and wavelet method is the most efficient algorithm.
