TL;DR: This paper makes use of the Sentinel-3A/Sentinel-3B tandem phase to assess the benefits of the Open-Loop tracking mode compared to Closed-Loop and the importance of knowing whether a water target was associated with a fine-tuned Open- Loop Tracking Command or an interpolated one is stressed.

TL;DR: The problem and the need behind the FRM4ALT principle to achieve an objective Earth observation are examined, and the expected FRM products and services which are to come into being out of this new observational strategy are described.

TL;DR: In this paper, a review of the entire effort for calibrating the RA-2 sigma naught measurements, which lasted for almost seven years, is presented in detail the adopted methodology and the final outcome of the activity, providing the users with the correction (bias) to get the calibrated SNA and analyzing its stability during almost the entire Envisat lifetime.

TL;DR: In this paper, the authors present the method to estimate the range, datation and angle-of-arrival errors from the transponder data and apply it to six years of Baseline C data to derive potential biases and drifts.

TL;DR: Calibration results for the altimeter of Sentinel-3A Surface Topography Mission as determined at the Permanent Facility for Altimetry Calibration in west Crete, Greece are presented.
