Radarsat-2 based ice thickness charts are still in test phase because we have not received enough Baltic Sea ice data for Radarsat-2 parameter estimation. Radarsat-1 parametrization is used instead until enough Radarsat-2 data over Baltic Sea ice has been received.
Also, the quality of Radarsat-2 based thickness charts has not been evaluated. First evaluations and parameter adjusting will be made during this winter 2008-2009.
Radarsat-2 is Canada's next-generation commercial SAR satellite, the follow-on to Radarsat-1. The new satellite was launched in December, 2007 on a Soyuz vehicle from Russia's Baikonur Cosmodrome in Kazakhstan. RADARSAT-2 has been designed with significant and powerful technical advancements which include 3m high-resolution imaging, flexibility in selection of polarization, left and right-looking imaging options, superior data storage and more precise measurements of spacecraft position and attitude. It's operating at C-band and its radar frequency is 5.405 GHz.
