This report is concerned with the combination of terrestrial information and satellite information for the determination of geocentric station positions alone, or geocentric station positions and gravitational potential coefficients. The method uses terrestrial information such as astronomic latitude and longitude, gravimetrically derived deflections of the vertical and height anomalies, with an adopted reference figure to define a geocentric position. The satellite data will include geocentric station positions and potential coefficients. The two models formed in this paper use a datum shift vector as the intermediate quantity. All equations for the necessary computations are made with no numerical results being obtained at this time.
