uncertainty in independent variables in a least squares adjustment. The application of these formalisms to GRACE is described, followed by a detailed analysis of the results both in terms of estimated satellite orientations and in terms of estimated gravity field solutions. Chapter 10 marks the end of the main body, summarizing the findings and giving an outlook on possible future avenues for research in this area. 3
