Abstract : Research is in progress at the Defense Mapping Agency Aerospace Center (DMAAC) to develop an improved earth gravitational model from a combination of satellite tracking and surface mean free-air gravity anomaly data. Analysis and techniques for obtaining combination solutions as well as the resulting gravitational model evaluation procedures are discussed. For comparison purposes, some of the evaluation procedures applied to the DMAAC derived and the 1969 Smithsonian Standard Earth (II) gravitational models are presented. (Author)
