Cryosat-2: Impact of Mission Resuscitation on Data System
SpaceOps 2010 Conference, 2010In October 2005, a launcher failure ended the CryoSat mission before that a single bit could be processed by the Ground Segment. Since the future of the mission was not known a formal close-down of the activities, including the documentation and all systems was performed, ensuring consolidation of pending issues and configuration control of all the ...

Calibration of the CryoSat-2 Interferometer and Measurement of Across-Track Ocean Slope
IEEE Transactions on Geoscience and Remote Sensing, 2013This paper describes the calibration of the CryoSat-2 interferometer, whose principal purpose is to accurately measure the height of the Antarctic and Greenland ice sheets. A sequence of CryoSat-2 data acquisitions over the tropical and midlatitude oceans were obtained between June and September 2010, from the SIRAL “A” and redundant SIRAL “B” radars ...

Orbit accuracy at the 12th year anniversary of Cryosat-2 mission
2022For the CryoSat-2 mission precision orbit determination (POD) is performed with the DORIS system and satellite laser ranging. The POD method requires that there are accurate models to describe the accelerations acting on the satellite. The importance of dynamic models increases when the tracking data is not continuously available; due to the 725 km ...

Accuracy and Performance of CryoSat-2 SARIn Mode Data Over Antarctica
IEEE Geoscience and Remote Sensing Letters, 2015The instrument onboard CryoSat-2 has a new measurement mode to improve performance on the steeper margins of the ice sheets where conventional radar altimetry has been limited in accuracy and coverage. We assess the accuracy of CryoSat-2 synthetic aperture radar interferometric (SARIn) mode data using data from Geoscience Laser Altimeter System onboard

Assessment of CryoSat-2 SAR mode wind and wave data
Advances in Space Research, 2018Abstract Significant wave height (SWH) and surface wind speed (WS) products from the CryoSat-2 Delay-Doppler, which is commonly known as Synthetic Aperture Radar (SAR), Mode are validated against operational ECMWF atmospheric and wave model results in addition to available observations from buoys, platforms and Jason-2 altimeter.

Is the CryoSat-2 orbit accuracy affected by space weather
2016We produce CryoSat-2 orbit solutions since June 2010 where we make of DORIS and satellite laser ranging tracking data. For CryoSat-2 the production of the orbits started in a solar minimum, next we went through a weak solar maximum from which we are currently returning to a minimum.

Evaluation of CryoSAT-2 for height retrieval over the Himalayan range
2012Climate warming over the 20th century has caused drastic changes in mountain glaciers globally, and of the Himalayan glaciers in particular. The stakes are high; mountain glaciers are the largest contributor to the increase in the mass of the world's oceans, and the Himalayas play a key role in the hydrology of the region, impacting on the economy ...
