| Abstract: | The origin and the properties of gravity gradiometry error of GOCE satellite are discussed and the method of simulating the time series of colored noise based on the AR model with the priori error PSD of the gradiometer is proposed. The theory about generating the stationary stochastic process based on the AR model is stated. We simulated noise time series based on the AR model according to two types of analytical instrument error PSD. The comparison between the analytical PSD and the PSD from the simulated noises shows that the AR model can be used for simulating the noise time series of gravity gradiometry of GOCE satellite. |
