Short summary
We compute gravity field solutions from kinematic orbit positions of GRACE. These positions are derived from GPS based observations, and hence, they are contaminated by measurement noise. We present three methods of dealing with the noise in the data to obtain not only high-quality gravity field solutions but also an accurate quality information of the gravity fields.
