Abstract

This chapter is dedicated to the GRACE Gravity Sensor System. In the following, a brief description of the individual components of the sensor system is given, followed by an overview of the interaction of the sensor system with the environment of the GRACE satellites and a brief description of the gravitational and non-gravitational forces acting on the satellites. As an example, the sensor performance of the accelerometer is estimated by real data analysis. It is demonstrated that the sensor performance agrees with its specification and that the derived data processing model enhancements currently yield no amelioration of the derived gravity field models quality.
