The average acceleration approach applied to gravity coefficients recovery based on GOCE orbits

The average acceleration approach was applied to recover a gravity field model Model_ACA from GOCE precise science orbits from September 2 to November 2, 2010, and furthermore a so called sequential least square adjustment was used. The model was compared with other gravity field models based on CHA...
