Abstract Helmert parameter method of variance component estimation in adjustment of gravity network may be greatly influnced by the observations with outliers. We try to combine it with the model of robust estimation based on equivalent variancecovariance, and use it to process the obsrevations of the Lushan mountain calibration line and the Anhui gravity network. The results show that the method can solve the outlier problems efficaciously.
