The forthcoming GOCE mission will provide gravity gradient observations along its orbit at varying altitude. It is necessary for certain data processing strategies to project the GOCE gravity gradients to a mean reference sphere. In the present simulation study the radial distance of the projection is in the order of 10 km, and can be done using the Taylor expansion of the gravity gradients.

In this paper we present an error analysis of such a projection. The omission of higher-order terms of the Taylor expansion and commission errors of the geopotential model are discussed.

The paper presents an error analysis study based on simulated GOCE gradiometry. The results are validated with stringent accuracy requirements of the GOCE mission.
