Geodetic analysis of Skylab altimetry preliminary data - SL/2 EREP pass 9 [PDF]
The author has identified the following significant results. The analysis was based on a time series intrinsic relationship between the satellite ephemeris, altimeter measured ranges, and the corresponding a priori values of subsatellite geoidal heights.

Mean gravity anomalies and sea surface heights derived from GEOS-3 altimeter data [PDF]
Approximately 2000 GEOS-3 altimeter arcs were analyzed to improve knowledge of the geoid and gravity field. An adjustment procedure was used to fit the sea surface heights (geoid undulations) in an adjustment process that incorporated cross-over ...

The application of Skylab altimetry to marine geoid determination [PDF]
The author had identified the following significant results. The major results can be divided broadly into two groups. One group is concerned with the effects of errors inherent in the various input data, such as the orbit emphemeris, a priori geoid etc.
