Abstract：The local geoid or gravity anomaly as an example is refined by the fusion of the simulated geoid height and gravity anomaly data,and the effects of observation noise level and nonstationary noise to the data fusion results are analyzed. Simulation tests show that the satisfactory results can be obtained by the fusion of different observation noise level data or nonstationary noise data with doubleinput singleoutput method.
