Abstract：The main task of network adjustment of airborne gravimetry is to compensate systemic errors. In order to weaken the influence of outliers and improve the effect of compensation, this paper brings in thresholding and robust estimation, and confirms these two methods’ validity and reliability in simulated data processing. By means of comparison，a conclusion is reached that the robust estimation has more practical value in the network adjustment of airborne gravimetry.
