CryoSat-2 - Four Years of Operations
SpaceOps 2014 Conference, 2014The CryoSat-2 spacecraft is one of the Earth Explorer Opportunity missions of the ESA Living Planet programme. It is operated by the European Space Operations Centre, in Darmstadt. The CryoSat Mission objective, fulfilled by the CryoSat-2 satellite, is to provide global continuous measurements of the ice cover variations on the Polar caps and ...

Improvement of a radiation model for Cryosat-2
2014In this paper we discuss the precision orbit modeling of Cryosat-2 launched on 8-April-2010 to map the cryosphere with an advanced radar altimeter system. The satellite is tracked with laser and DORIS for which we find residuals of 1.58 cm and 0.4 mm/sec respectively.

CryoSat-2 Ocean Altimetry Assessment
2016CryoSat-2 was launched April 2010 and has been monitoring the Earth’s cryosphere and oceans since with unprecedented accuracy and precision by an ice-dedicated altimeter capable of measuring in LRM, SAR and SARin mode. In this paper we validate CryoSat-2 LRM, RDSAR, IOP and GOP ocean data and assess their quality in comparison with other altimeters by ...

CryoSat-2 Ocean Altimetry Assessment
2017CryoSat-2 was launched on the 8th of April 2010, the primary purpose of the mission is to measure sea ice thickness, however the mission is also able to monitor land ice volume variations and ocean height changes. The primary instrument is the Siral altimeter, it comes with an unprecedented accuracy and precision capable of measuring in a low ...

A demonstration of the potential of Cryosat-2 to contribute to mesoscale observation
Advances in Space Research, 2012Abstract Cryosat-2 was designed for its primary scientific objectives, i.e. for cryosphere science. As far as oceanography is concerned, various mission design choices make it less accurate than missions designed to comply with ocean surface topography requirements such as Jason-2 or ENVISAT.

Validation of the extended CryoSat-2 ocean data products
2017Operational marine products from CryoSat-2, generated by a dedicated processor, have been available since April 2014. Here we present some results of a verification and scientific validation of the Geophysical Ocean Products (GOP), which have consolidated orbits and are available 30 days after acquisition.

Precision orbit determination performance for CryoSat-2
Advances in Space Research, 2018Abstract In this paper we discuss our efforts to perform precision orbit determination (POD) of CryoSat-2 which depends on Doppler and satellite laser ranging tracking data. A dynamic orbit model is set-up and the residuals between the model and the tracking data is evaluated. The average r.m.s. of the 10 s averaged Doppler tracking pass residuals is

Improved retrieval of sea ice thickness from SMOS and CryoSat-2
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015We investigate the potential of a synergetic combination of data from ESA's SMOS and CryoSat-2 mission for sea ice thickness retrieval. SMOS and CryoSat-2 provide complementary information because of their different spatio-temporal sampling and resolution, and because of the complementary uncertainty due to the fundamental difference of the radiometric

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 ...
