Recovery of Mean Gravity Anomalies from Satellite - Satellite Range Rate Data Using Least Squares Collocation
Author: Reinhard RummelPublisher:
ISBN:
Category : Gravity anomalies
Languages : en
Pages : 61
Book Description
Range rate data between two satellites can be used to determine acceleration along the connecting line between two satellites by numerically differentiating an analytic representation of this data. Using a reference potential field this acceleration can be interpreted to be a derivative of the disturbing potential along the line of the satellites. Using geometric techniques, the radial component of the disturbing potential can be estimated. This component can then be incorporated in the determination of mean gravity anomalies at the surface of the earth using least squares collocation and theorectical covariance functions. This paper discusses the theoretical basis of the above procedures and describes two simulation studies performed.

Book Description
The prediction of mean gravity anomalies from other anomalies and satellite altimeter data is described using the technique of least squares collocation. The equations derived are then used in simulation studies, using altimeter data alone, to estimate the accuracy to which mean gravity anomalies can be determined with respect to an ellipsoidal reference field and a degree 12 reference field.

Book Description
We previously described (14,14) spherical-harmonic global adjustments of satellite altimetry using the AFGL short-arc technique supplemented with point masses to allow incorporation of short-wavelength geoidal detail. Recently, we have also investigated another technique to enhance short-wavelength detail: least squares collocation with noise. Both methods provide a means to determine a high resolution gravity field on a local, regional or global scale. Statistical comparisons of these two methods have been made in selected areas and the results tabulated.
