Timeliness of Correcting Baseline Error in Wide-Swath Altimeter Based on Reference Topography Data
Remote Sensing, 2023 The baseline error is a primary error source of the wide-swath altimeter, directly related to the cross-track distance, and can lead to serious height errors at the swath’s outer edge.

Inversion method of deflection of the vertical based on SWOT wide-swath altimeter data
Geodesy and GeodynamicsThe deflection of the vertical (DOV) is the key information in the study of ocean gravity field. However, in most areas, the precision of the prime component of DOV is significantly lower than that of the meridian component. To obtain higher accuracy and

Effects of Interferometric Radar Altimeter Errors on Marine Gravity Field Inversion [PDF]
Sensors, 2020 The traditional altimetry satellite, which is based on pulse-limited radar altimeter, only measures ocean surface heights along tracks; hence, leads to poorer accuracy in the east component of the vertical deflections compared to the north component ...

Contribution of a Wide-Swath Altimeter in a Shelf Seas Assimilation System: Impact of the Satellite Roll Errors [PDF]
Journal of Atmospheric and Oceanic Technology, 2008 Abstract The authors investigate the potential qualitative improvement brought by wide-swath, interferometry-based ocean altimetry measurements with respect to classical nadir altimeters in a coastal/shelf data assimilation system. In addition, particular attention is paid to roll errors, which could significantly reduce the expected ...
