Abstract
Theoretically,the geopotential on the geoid,geoid constant W_0,determines the gure and size of the geoid.The systmetic error from W_0 will directly give rise to the shift of the geoid.Hence,how to accurately determine W_0 is a problem seriously interested by many geodesists.In this paper,based on the ctitious compress recovery approach,an approach different from the conventional methods for determining the geoid geopotential shift W is provided.
