Radarsat-2 is a Canadian earth observation satellite .
It was launched on December 14, 2007 from the Baikonur spaceport in Kazakhstan . The earth observation satellite was built by the Canadian company MDA Space Missions and is operated by the Canadian space agency, the Canadian Space Agency (CSA) . The satellite has a SAR ( Synthetic Aperture Radar ) sensor with different polarization modes. Among other things, data of the four channels HH, HV, VV and VH can be recorded simultaneously in the fully polarimetric mode. The highest geometric resolution of the satellite is 3 m, with a positional accuracy of 100 m. Data with a swath width of up to 500 km can be recorded. The frequency of the broadcast signal is 5.405 GHz (C-band).
Data from the satellite can be used for a wide variety of applications, including land use mapping, sea ice mapping, ship monitoring and flood mapping.
Radarsat-2 is a successor to Radarsat-1 . Radarsat-2 flies in a sun-synchronous orbit at an altitude of 798 km.
use
Like its predecessor, Radarsat-1, the satellite is used not only for research but also for international cooperation on space and natural disasters.
