Abstract

A study has been made of the gravity field of the earth using a combined solution from free air anomalies and satellite data. Spherical harmonics up to order 8.8 have been computed in a joint solution. Satellite data from Doppler tracking (NWL) and optical observations (SAO) were added in a combined solution with full consideration of the complete covariance matrix.—This study was based on the most complete set of gravity data so far presented (approximately 500,000).
