In the course of level 2 data processing for the GOCE (Gravity Field and Steady–State Ocean Circulation Explorer) satellite mission different streams of level 1b data will be merged in a single solution providing the Earth’s gravity field, but also state-vector parameters and other quantities. A proper weighting of orbit tracking data, gravity gradiometry data and certain a priori information, usually considered as ‘solution constraints’, can be expected as crucial for the solution quality. But… CONTINUE READING
