Abstract:

The along-track geoid heights and vertical deflections over the oceans are estimated by a Wiener filter based on The Analytic Sciences Corporation TASC Model with pre-filter parameters derived from an analysis of the GEOS-III satellite radar altimetry data. A study of 81 passes 716 intersections of the radar altimetry data from the Perth, Australia telemetry site shows a mean geoid height difference of 0.75 m and a standard deviation of 2.33 m before bias removal, and a mean geoid height of -0.06 m and a standard deviation of 0.53 m after bias removal. The geoidal contours derived from this data reveal known geoidal features in regions where ship surveys are available. Author
